This allows prototyping rfcore.c improvements from Python.
This was mostly written by @dpgeorge with small modifications to work after
rfcore_init() by @jimmo.
Before this change there was up to a 128ms delay on incoming payloads from
CPU2 as it was polled by SysTick. Now the RX IRQ immediately schedules the
PendSV.
This is required to allow using WS firmware newer than 1.1.1 concurrently
with USB (e.g. USB VCP). It prevents CPU2 from modifying the CLK48 config
on boot.
Tested on WS=1.8 FUS=1.1.

- Split tables and buffers into SRAM2A/2B.
- Use structs rather than word offsets to access tables.
- Use FLASH_IPCCDBA register value rather than option bytes directly.
This allows `ble.active(1)` to fail correctly if the HCI controller is
unavailable.
It also avoids an infine loop in the NimBLE event handler where NimBLE
doesn't correctly detect that the HCI controller is unavailable and keeps
trying to reset.
Furthermore, it fixes an issue where GATT service registrations were left
allocated, which led to a bad realloc if the stack was activated multiple
times.
MicroPython and NimBLE must be on the same core, for synchronisation of the
BLE ringbuf and the MicroPython scheduler. However, in the current IDF
versions (3.3 and 4.0) there are issues (see e.g. #5489) with running
NimBLE on core 1.
This change - pinning both tasks to core 0 - makes it possible to reliably
run the BLE multitests on esp32 boards.
This commit adds support for using Bluetooth on the unix port via a H4
serial interface (distinct from a USB dongle), with both BTstack and NimBLE
Bluetooth stacks.
Note that MICROPY_PY_BLUETOOTH is now disabled for the coverage variant.
Prior to this commit Bluetooth was anyway not being built on Travis because
libusb was not detected. But now that bluetooth works in H4 mode it will
be built, and will lead to a large decrease in coverage because Bluetooth
tests cannot be run on Travis.
Previously the interaction between the different layers of the Bluetooth
stack was different on each port and each stack. This commit defines
common interfaces between them and implements them for cyw43, btstack,
nimble, stm32, unix.
mp_irq_init() is useful when the IRQ object is allocated by the caller.
The mp_irq_methods_t.init method is not used anywhere so has been removed.

By setting MICROPY_EPOCH_IS_1970 a port can opt to use 1970/1/1 as the
Epoch for timestamps returned by stat(). And this setting is enabled on
the unix and windows ports because that's what they use.

On 32-bit builds these stat fields will overflow a small-int, so use
mp_obj_new_int_from_uint to construct the int object.

gettimeofday returns seconds since 2000/1/1 so needs to be adjusted to
seconds since 1970/1/1 to give the correct return value of mp_hal_time_ns.

Updating to Black v20.8b1 there are two changes that affect the code in
this repository:
- If there is a trailing comma in a list (eg [], () or function call) then
that list is now written out with one line per element. So remove such
trailing commas where the list should stay on one line.
- Spaces at the start of """ doc strings are removed.

Prior to this commit, if you configure a pin as an output type (I2C in this
example) and then later configure it back as an input, then it will report
the type incorrectly. Example:
>>> import machine
>>> b6 = machine.Pin('B6')
>>> b6
Pin(Pin.cpu.B6, mode=Pin.IN)
>>> machine.I2C(1)
I2C(1, scl=B6, sda=B7, freq=420000)
>>> b6
Pin(Pin.cpu.B6, mode=Pin.ALT_OPEN_DRAIN, pull=Pin.PULL_UP, af=Pin.AF4_I2C1)
>>> b6.init(machine.Pin.IN)
>>> b6
Pin(Pin.cpu.B6, mode=Pin.ALT_OPEN_DRAIN, af=Pin.AF4_I2C1)
With this commit the last print now works:
>>> b6
Pin(Pin.cpu.B6, mode=Pin.IN)
Include storage/flash_map.h unconditionally so we always have access to the
FLASH_AREA_LABEL_EXISTS macro, even if CONFIG_FLASH_MAP is not defined.
This fixes a build error for the qemu_x86 board:

The SCSI driver calls GetCapacity to get the block size and number of
blocks of the underlying block-device/LUN. It caches these values and uses
them later on to verify that reads/writes are within the bounds of the LUN.
But, prior to this commit, there was only one set of cached values for all
LUNs, so the bounds checking for a LUN could use incorrect values, values
from one of the other LUNs that most recently updated the cached values.
This would lead to failed SCSI requests.
This commit fixes this issue by having separate cached values for each LUN.

Enabling the following features for all targets, except for nrf51
targets compiled to be used with SoftDevice:
- MICROPY_PY_ARRAY_SLICE_ASSIGN
- MICROPY_PY_SYS_STDFILES
- MICROPY_PY_UBINASCII
Splitting mpconfigport.h into multiple device specific
files in order to facilitate variations between devices.
Due to the fact that the devices might have variations in
features and also variations in flash size it makes sense
that some devices offers more functionality than others
without being limited by restricted devices.
For example more micropython features can be activated for
nrf52840 with 1MB flash, compared to nrf51 with 256KB.
This code is imported from musl, to match existing code in libm_dbl.
The file is also added to the build in stm32/Makefile. It's not needed by
the core code but, similar to c5cc64175b,
allows round() to be used by user C modules or board extensions.
A previous commit 3a9d948032 can cause
lock-ups of the RMT driver, so this commit reverses that, adds a loop_en
flag, and explicitly controls the TX interrupt in write_pulses(). This
provides correct looping, non-blocking writes and sensible behaviour for
wait_done().
