Glenn Ruben Bakke 2489688635 nrf/boards: Update memory.ld to include bootloader offsets.
Adding variables that can be set from other linker scripts:

- _bootloader_head_size:
    Bootloader flash offset in front of the application.

- _bootloader_tail_size:
    Bootloader offset from the tail of the flash.
    In case the bootloader is located at the end.

- _bootloader_head_ram_size:
    Bootloader RAM usage in front of the application.

Updated calculations of application flash and RAM.

Damien George 64180f0742 extmod/machine_i2c: Add init protocol method for generic I2C bindings.
Hardware I2C implementations must provide a .init() protocol method if they
want to support reconfiguration.  Otherwise the default is that i2c.init()
raises an OSError (currently the case for all ports).

mp_machine_soft_i2c_locals_dict is renamed to mp_machine_i2c_locals_dict to
match the generic SPI bindings.

Fixes issue #6623 (where calling .init() on a HW I2C would crash).

Damien George 71f3ade770 ports: Support legacy soft I2C/SPI construction via id=-1 arg.
With a warning that this way of constructing software I2C/SPI is
deprecated.  The check and warning will be removed in a future release.

This should help existing code to migrate to the new SoftI2C/SoftSPI types.

Damien George 39d50d129c ports: Add SoftI2C and SoftSPI to machine module where appropriate.
Previous commits removed the ability for one I2C/SPI constructor to
construct both software- or hardware-based peripheral instances.  Such
construction is now split to explicit soft and non-soft types.

This commit makes both types available in all ports that previously could
create both software and hardware peripherals: machine.I2C and machine.SPI
construct hardware instances, while machine.SoftI2C and machine.SoftSPI
create software instances.

This is a breaking change for use of software-based I2C and SPI.  Code that
constructed I2C/SPI peripherals in the following way will need to be
changed:

    machine.I2C(-1, ...)            ->  machine.SoftI2C(...)
    machine.I2C(scl=scl, sda=sda)   ->  machine.SoftI2C(scl=scl, sda=sda)

    machine.SPI(-1, ...)            ->  machine.SoftSPI(...)
    machine.SPI(sck=sck, mosi=mosi, miso=miso)
                        ->  machine.SoftSPI(sck=sck, mosi=mosi, miso=miso)

Code which uses machine.I2C and machine.SPI classes to access hardware
peripherals does not need to change.

  that list is now written out with one line per element.  So remove such
  trailing commas where the list should stay on one line.

Splitting mpconfigport.h into multiple device specific

For example more micropython features can be activated for
nrf52840 with 1MB flash, compared to nrf51 with 256KB.

Martin Fischer 15574cd665 nrf: Add support for time.ticks_xxx functions using RTC1.
This commit adds time.ticks_ms/us support using RTC1 as the timebase.  It
also adds the time.ticks_add/diff helper functions.  This feature can be
enabled using MICROPY_PY_TIME_TICKS.  If disabled the system uses the
legacy sleep methods and does not have any ticks functions.

In addition support for MICROPY_EVENT_POLL_HOOK was added to the
time.sleep_ms(x) function, making this function more power efficient and
allows support for select.poll/asyncio.  To support this, the RTC's CCR0
was used to schedule a ~1msec event to wakeup the CPU.

Some important notes about the RTC timebase:

- Since the granularity of RTC1's ticks are approx 30usec, time.ticks_us is
not perfect, does not have 1us resolution, but is otherwise quite usable.
For tighter measurments the ticker's 1MHz counter should be used.

- time.ticks_ms(x) should *not* be called in an IRQ with higher prio than
the RTC overflow irq (3).  If so it introduces a race condition and
possibly leads to wrong tick calculations.

See #6171 and #6202.

Damien George d2384efa80 py: Automatically provide weak links from "foo" to "ufoo" module name.
This commit implements automatic module weak links for all built-in
modules, by searching for "ufoo" in the built-in module list if "foo"
cannot be found.  This means that all modules named "ufoo" are always
available as "foo".  Also, a port can no longer add any other weak links,
which makes strict the definition of a weak link.

It saves some code size (about 100-200 bytes) on ports that previously had
lots of weak links.

Some changes from the previous behaviour:
- It doesn't intern the non-u module names (eg "foo" is not interned),
  which saves code size, but will mean that "import foo" creates a new qstr
  (namely "foo") in RAM (unless the importing module is frozen).
- help('modules') no longer lists non-u module names, only the u-variants;
  this reduces duplication in the help listing.

Weak links are effectively the same as having a set of symbolic links on
the filesystem that is searched last.  So an "import foo" will search
built-in modules first, then all paths in sys.path, then weak links last,
importing "ufoo" if it exists.  Thus a file called "foo.py" somewhere in
sys.path will still have precedence over the weak link of "foo" to "ufoo".

Glenn Ruben Bakke 82fe6b0526 nrf: Add nrf9160 base support.
This patch add basic building blocks for nrf9P60.

It also includes a secure bootloader which forwards all
possible peripherals that are user selectable to become
non-secure. After configuring Flash, RAM and peripherals
the secure bootloader will jump to the non-secure domain
where MicroPython is placed.

The minimum size of a secure boot has to be a flash
block of 32Kb, hence why the linker scripts are
offsetting the main application this much.

The RAM offset is set to 128K, to allow for later
integration of Nordic Semiconductor's BSD socket
library which reserves the range 0x20010000 - 0x2001FFFF.

Also, the LED module has been updated to support individual base level
configuration of each LED. If set, this will be used instead of the

MICROPY_HW_LEDX_LEVEL, where X is the LED number can be used to set
the base level of the specific LED.

Damien George 0646e607b5 ports: Convert to use pyexec_file_if_exists() to execute boot/main.py.
The stm32 and nrf ports already had the behaviour that they would first
check if the script exists before executing it, and this patch makes all
other ports work the same way.  This helps when developing apps because
it's hard to tell (when unconditionally trying to execute the scripts) if
the resulting OSError at boot up comes from missing boot.py or main.py, or
from some other error.  And it's not really an error if these scripts don't
exist.

Glenn Ruben Bakke 4a323f8b80 nrf/nrfx_config: Move back nrf52832 to use non-EasyDMA SPI
As EasyDMA variant of SPI(M) might clock out an additional byte
in single byte transactions this patch moves the nrf52832 to
use SPI and not SPIM to get more stable data transactions.

Ref: nrf52832 rev2 errata v1.1, suggested workaround is:
"Use the SPI module (deprecated but still available) or
use the following workaround with SPIM ..."

Current nrfx SPIM driver does not contain this workaround,
and in the meanwhile moving back to SPI fixes the issue.

Also, tabbing the nrfx_config.h a bit to make it more readable.

Glenn Ruben Bakke 24258cf0b9 nrf: Return immediatly from mp_hal_delay_us if 0us is given
After nrfx 1.0.0 a new macro was introduced to do a common
hardware timeout. The macro function triggers a counter of
retries or a timeout in us. However, in many cases, like in
nrfx_adc.c the timeout value is set to 0, leading to a infinite
loop in mp_hal_delay_us. This patch prevents this from happening.

Path of error:
nrfx_adc.c -> NRFX_WAIT_FOR -> NRFX_DELAY_US -> mp_hal_delay_us.

Glenn Ruben Bakke 6e8a605500 nrf/modules/machine/pin: Add support for IRQ on Pin's
This patch ads irq method to the pin object. Handlers
registered in the irq method will be kept as part of the
ROOT_POINTERS.

In order to resolve which pin object is the root of the
IRQ, the pin_find has been extended to also be able to
search up Pin objects based on mp_int_t pin number.
This also implies that the Pin.new API is now also supporting
creation of Pin objects based on the integer value of the
pin instead of old style mandating string name of the Pin.

All boards have been updated to use real pin number from
0-48 instead of pin_Pxx for UART/SPI and music module pins.

UART/SPI/modmusic has also been updated to use pin number
provided directly or look up the Pin object based on the
integer value of the pin (modmusic).

Pin generation has been updated to create a list of pins, where
the board/cpu dicts are now refering to an index in this list
instead of having one const declaration for each pin. This new
const table makes it possible to iterate through all pins generated
in order to locate the correct Pin object.

Glenn Ruben Bakke 864f671744 nrf: Remove port member from Pin object
In order to be able to support GPIO1 port on nrf52840
the port has been removed from the Pin object.

All pins on port1 will now be incrementally on top of
the pin numbers for gpio0. Hence, Pin 1.00 will become
P32, and Pin 1.15 will become P47.

The modification is done to address the new gpio HAL
interface in nrfx, which resolves the port to be
configured base on a multiple of 32.

The patch also affects the existing devices which does
not have a second GPIO port in the way that the
port indication A and B is removed from Pin generation.
This means that the port which was earlier addressed
as PA0 is now P0, and PA31 is P31.

Also, this patch removes the gpio member which earlier
pointed to the perihperal GPIO base address. This is not
needed anymore, hence removed.

glennrub 002f7d1ad7 nrf: Replace custom-HAL with nrfx-HAL
Summarized this squashed PR replaces the hal/ folder in the port. This has been replaced the official
HAL layer from Nordic Semiconductor; https://github.com/NordicSemiconductor/nrfx.

A Git submodule has been added under lib/nrfx, for the nrfx dependency.

The drivers / modules has been updated to use this new HAL layer; nrfx at v1.0.0.

Also, header files and system files for nrf51/nrf52x chip variants has been deleted from the device/ folder, only keeping back the startup files written in C. All other files are now fetched from nrfx.

3 new header files in the ports/nrf/ folder has been added to configure nrfx (nrfx_config.h), logging (nrfx_log.h) and glue nrfx together with the drivers and modules from micropython (nrfx_glue.h).

The PR has been a joint effort from @aykevl (Ayke van Laethem) and @glennrub.

For reference, the commit log will be kept to get an overview of the changes done:

* ports/nrf: Initial commit for moving hal to Nordic Semiconductor BSD-3 licensed nrfx-hal.

* ports/nrf: Adding nrfx, Nordic Semiconductor BSD-3 hal layer, as git submodule checked out at lib/nrfx.

* ports/nrf/modules/machine/uart: Fixing bug which set hwfc to parity excluded, always resulting in no flow control, hence corrupted output. Also adding an extra loop on uart_tx_char to prevent any tx when any ongoing tx is in progress.

* ports/nrf/i2c: Moving I2C over to nrfx driver.

* ports/nrf/modules/machine/i2c: Alignment. Renaming print function param 'o' to 'self_in'

* ports/nrf/spi: Updating SPI machine module to use nrfx drivers.

* ports/nrf: Renaming modules/machine/rtc.c/.h to rtcounter.c/.h to not confuse the peripheral with Real-Time Clock:

* ports/nrf: Updating various files after renaming machine module RTC to RTCounter.

* ports/nrf: Renaming RTC to RTCounter in modmachine globals dict table. Also updating object type name to reflect new module name.

* ports/nrf: Fixing leftovers after renaming rtc to rtcounter.

* ports/nrf: Early untested adoption of nrfx_rtc in RTCounter. Untested.

* nrf/modules/machine/i2c: Improve keyword argument handling

* ports/nrf/modules/temp: Updating Temp machine module to use nrfx defined hal nrf_temp.h. Moving logic of BLE stack awareness to machine module.

* ports/nrf/boards/pca10040: Enable machine Temp module.

* nrf/modules/machine/rtcounter: Remove magic constants.

* ports/nrf: Adding base support for nrfx module logging. Adding option to disable logging of UART as it might log its own setup over UART while the peripheral is not yet set up. Logging of UART could make sense if other transport of log is used.

* ports/nrf: updating nrfx_log.h with more correct parenthisis on macro grouping.

* ports/nrf: Updating nrfx logging with configuration to disable logging of UART module. The pattern can be used to turn off other modules as well. However, for now UART is the only module locking itself by logging before the peripheral is configured. Logging is turned off by default, can be enabled in nrfx_config.h by setting NRFX_LOG_ENABLED=1.

* ports/nrf/modules/random: Updating modrandom to use nrfx hal for rng. Not using nrfx-driver for this peripheral as its blocking mode would do the trick on RNG. Moving softdevice aware code from legacy hal to modrandom.c.

* nrf: Enable Peripheral Resource Sharing.

This enables TWI and SPI to be enabled at the same time.

* nrf/Makefile: Define MCU sub variant (e.g. NRF51822/NRF51422)

* nrf: Port TIMER peripheral to nrfx HAL.

* nrf/modules/machine/uart: Optimize UART module

For a nRF51, this results in a size reduction of:
.text: -68 bytes
.data: -56 bytes

* nrf/modules/machine/uart: Don't use magic index numbers.

* nrf/modules/machine/uart: Fix off-by-one error.

For nrf51:
.text: -40 bytes

* nrf/modules/machine/rtcounter: Update for nrfx HAL.

* nrf/modules/machine/i2c: Reduce RAM consumption.

Reductions for the nrf51:
flash: -108 bytes
RAM:   -72 bytes

* nrf/mpconfigport: Avoid unnecessary root pointers.

This saves 92 bytes of RAM.

* nrf: Support SoftDevice with nrfx HAL.

* nrf: Add NVMC peripheral (microbitfs) support.

There is no support yet for a SoftDevice.

It also fixes a potentially serious bug in start_index generation.

* nrf/modules/machine/spi: Optimize SPI peripheral.

nrf51:
text: -340 bytes
data: -72  bytes

nrf52:
text: -352 bytes
data: -108 bytes

* nrf/modules/random: Forgot to commit header file.

* nrf: Make nrfx_config.h universal for all boards.

* nrf: Use SoftDevice API for flash access when built for SD

* nrf/drivers/bluetooth: Remove legacy HAL driver includes.

These were not used anymore so can be removed.

* ports/nrf/microbit: Port microbit targets to nrfx HAL

Initial port of microbit modules to use nrfx HAL layer.
Tested display/image and modmusic on micro:bit to verify that
softpwm and ticker for nrf51 is working as expected.

Changing IRQ priority on timer to priority 2, as 1 might collide if
used side by side of SD110 BLE stack.

The patch reserves Timer1 peripheral compile time. This is not ideal
and should be resolved in seperate task.

* nrf/boards/microbit: Remove custom nrfx_config.h from microbit target, adding disablement of timer1 if softpwm is enabled.

* nrf/adc: Update ADC module to use nrfx

* nrf/modules/machine/pwm: Updating machine PWM module to use nrfx HAL driver.

examples/nrf52_pwm.py and examples/nrf52_servo.py tested on pca10040.

* nrf: Removing hal folder and boards nrf5x_hal_conf.h headers.

* nrf/nrfx_glue: Adding direct NVIC access for S110 BLE stack

If SoftDevice s110 has not yet been initialized, the IRQ will not be forwarded to
the application using the sd_nvic* function calls. Hence, direct access to cmsi
nvic functions are used instead if SoftDevice is not enabled.

* nrf/drivers/ticker: Setting IRQ priority 3 on Timer1

SoftDevice fails to initilize if Timer1 has been configured to priority
level 2 before enabling the SD. The timer is set to priority 1, higher than BLE
stack in order to provide better quality of music rendering when used with the
music module. This might be too high, time will show.

* nrf/examples: Updating ubluepy_temp after moving RTCounter to nrfx.

* nrf: delete duplicate files from device folder which can be located in nrfx/mdk.

* nrf/Makefile: Fetch system files from nrfx.

Testing on each device sub-variant to figure out which system file to
use. Reason for this is that nrf52.c is actually defining nrf52832.

Removing NRF_DEFINES parameter setting the device in use into the
same sub-variant test, as NRF52 is unique to nrf52832 when using nrfx.
Without this exclusion of -DNRF52 in compilation for nrf52840, the
device will be interpreted as a nrf52, hence nrf52832.

Also, changing name on variable SRC_NRF_HAL to SRC_NRFX_HAL to
explicitly tell the origin of the file.

* nrf: Updating device #ifdefs to be more open to non-nrf51 targets.

* nrf/modules/machine/uart: Removing second instance of UART for nrf52840 as it only has one non-DMA variant.

* nrf/device: Removing system files as these are now used from nrfx/mdk

* nrf: Moving startup files in device one level up as there is no need for deep hierarchy.

* nrf: Use NRF52_SERIES defined in nrfx/mdk/nrf.h as define value when testing for both nrf52(832) and nrf52840 variants.

* nrf/modules/machine/uart: Enable UART RX by default

Enable rx by default after intiialization of the peripheral.
Else, the nrfx driver will re-enable rx for each byte read
on uart REPL, clearing the EVENT_RXDRDY before second byte,
which again will make second byte get lost and read will get stuck.

This happens if the bytes are transmitted nrf(51) while still
processing the previous byte. Not seen on nrf52, but should
also become an issue at higher speeds.

This patch sets rx to always be enabled. Hence, not clearing the event
between read bytes, and it will be able to detect next byte recieved
upon finishing the first.

* nrf/modules/machine/timer: Fixing defines excluding Timer1 if ticker/softpwm is used.

* nrf: Switching import form mpconfigboard.h to mpconfigport.h in nrfx_config.h as mpconfigboard.h might define default values for defines not set by board specific header.

* nrf/modules/machine/i2c: nrfx integration fixes

Increasing speed to 400K.

Returning Address NACK's as MP error code; MP_ENODEV.

Returning MP_ETIMEOUT on all other error codes from TWI nrfx driver
except the ANACK.

Enabling and disabling the TWI peripheral before and after each transaction.

* nrf/examples: Updating ssd1306_mod.py to split framebuffer transfer into multiple chunks

* nrf/modules/machine/i2c: Return MP_EIO error if Data NACK occurs.

* nrf: Addressing review comments.

* nrf: Updating git submodule and users to nrfx v1.0.0.

* nrf/modules/machine/adc: Update adc module to follow v1.0.0 nrfx API.

* nrf/modules/machine/spi: Implement init and deinit functions

Extending SPI objects with a config member such that
configuration can be kept between new() and init().

Moving initialization done in new() to common init
function shared between the module functions.

If SPI is already configured, the SPI peripheral will
be uninitialized before initalized again.

Adding logic to handle initialization of polarity and
phase. As well, updating default speed to 1M from 500K.

The nrf51x22_256k_16k_s110_8.0.0.ld had a stack size of only 1kB, which
is way too low. Additionally, the indicated _minimum_stack_size (set at
