Jim Mussared a377302623 extmod/modnetwork: Add network.hostname() and network.country().
This provides a standard interface to setting the global networking config
for all interfaces and interface types.

For ports that already use either a static hostname (mimxrt, rp2) they will
now use the configured value. The default is configured by the port
(or optionally the board).

For interfaces that previously supported .config(hostname), this is still
supported but now implemented using the global network.hostname.

Similarly, pyb.country and rp2.country are now deprecated, but the methods
still exist (and forward to network.hostname).

Because ESP32/ESP8266 do not use extmod/modnetwork.c they are not affected
by this commit.

robert-hh de1f1dd164 shared/runtime/softtimer: Use consistently the same clock source.
Before, both uwTick and mp_hal_ticks_ms() were used as clock source.  That
assumes, that these two are synchronous and start with the same value,
which may be not the case for all ports.  If the lag between uwTick and
mp_hal_ticks_ms() is larger than the timer interval, the timer would either
rush up until the times are synchronous, or not start until uwTick wraps
over.

As suggested by @dpgeorge, MICROPY_SOFT_TIMER_TICKS_MS is now used in
softtimer.c, which has to be defined in a port's mpconfigport.h with
the variable that holds the SysTick counter.

Note that it's not possible to switch everything in softtimer.c to use
mp_hal_ticks_ms() because the logic in SysTick_Handler that schedules
soft_timer_handler() uses (eg on mimxrt) the uwTick variable directly
(named systick_ms there), and mp_hal_ticks_ms() uses a different source
timer.  Thus it is made fully configurable.

robert-hh 5e990cc27f mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board.
The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.

The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
  being the 1GB interface.

The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.

This work was done in collaboration with @alphaFred.

robert-hh 9d2e179fa5 mimxrt: Fix CPU freeze when calling __WFE() in MICROPY_EVENT_POLL_HOOK.
This issue affected i.MX RT 1052, 1062 and 1064.  It seems to be addressed
by Errata ERR006223, which also mentions i.MX RT101x and 102x, but these
devices worked well even without the change.  As a side effect, the current
consumption at an idle REPL drops significantly with this fix.

Fixes issue #7235.

Damien George 8f4c108025 all: Remove MICROPY_PY_IO_FILEIO config option.
Since commit e65d1e69e8 there is no longer an
io.FileIO class, so this option is no longer needed.

This option also controlled whether or not files supported being opened in
binary mode (eg 'rb'), and could, if disabled, lead to confusion as to why
opening a file in binary mode silently did the wrong thing (it would just
open in text mode if MICROPY_PY_IO_FILEIO was disabled).

The various VFS implementations (POSIX, FAT, LFS) were the only places
where enabling this option made a difference, and in almost all cases where
one of these filesystems were enabled, MICROPY_PY_IO_FILEIO was also
enabled.  So it makes sense to just unconditionally enable this feature
(ability to open a file in binary mode) in all cases, and so just remove
this config option altogether.  That makes configuration simpler and means
binary file support always exists (and opening a file in binary mode is
arguably more fundamental than opening in text mode, so if anything should
be configurable then it should be the ability to open in text mode).

For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.

This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
  nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

- 3 modes of operation:
  - blocking
  - non-blocking with callback
  - uasyncio
- configurable internal buffer
- optional MCK

Tested with the following development boards:
- MIMXRT1010_EVK, MIMXRT1015_EVK, MIMXRT1020_EVK, MIMXRT1050_EVK
- Teensy 4.0, Teensy 4.1
- Olimex RT1010
- Seeed ARCH MIX

robert-hh 81f706aee4 mimxrt: Support PWM using the FLEXPWM and QTMR modules.
Frequency range 15Hz/18Hz to > 1 MHz, with decreasing resolution of the
duty cycle.  The basic API is supported as documentated, except that
keyword parameters are accepted for both the instatiaton and the
PWM.init() call.

Extensions: support PWM for channel pairs.  Channel pairs are declared by
supplying 2-element tuples for the pins.  The two channels of a pair must
be the A/B channel of a FLEXPWM module.  These form than a complementary
pair.

Additional supported keyword arguments:

- center=value Defines the center position of a pulse within the pulse
  cycle.  The align keyword is actually shortcut for center.

- sync=True|False: If set to True, the channels will be synchronized to a
  submodule 0 channel, which has already to be enabled.

- align=PWM.MIDDLE | PMW.BEGIN | PWM.END. It defines, whether synchronized
  channels are Center-Aligned or Edge-aligned.  The channels must be either
  complementary a channel pair or a group of synchronized channels.  It may
  as well be applied to a single channel, but withiout any benefit.

- invert= 0..3. Controls ouput inversion of the pins.  Bit 0 controls the
  first pin, bit 1 the second.

- deadtime=time_ns time of complementary channels for delaying the rising
  slope.

- xor=0|1|2 xor causes the output of channel A and B to be xored.  If
  applied to a X channel, it shows the value oif A ^ B.  If applied to an A
  or B channel, both channel show the xored signal for xor=1.  For xor=2,
  the xored signal is split between channels A and B.  See also the
  Reference Manual, chapter about double pulses.  The behavior of xor=2 can
  also be achieved using the center method for locating a pulse within a
  clock period.

The output is enabled for board pins only.

CPU pins may still be used for FLEXPWM, e.g. as sync source, but the signal
will not be routed to the output.  That applies only to FLEXPWM pins.  The
use of QTMR pins which are not board pins will be rejected.

As part of this commit, the _WFE() statement is removed from
ticks_delay_us64() to prevent PWM glitching during calls to sleep().

This commit implements 10/100 Mbit Ethernet support in the mimxrt port.

The following boards are configured without ETH network:
- MIMXRT1010_EVK
- Teensy 4.0

The following boards are configured with ETH network:
- MIMXRT1020_EVK
- MIMXRT1050_EVK
- MIMXRT1060_EVK
- MIMXRT1064_EVK
- Teensy 4.1

Ethernet support tested with TEENSY 4.1, MIMRTX1020_EVK and MIMXRT1050_EVK.
Build tested with Teensy 4.0 and MIMXRT1010_EVK to be still working.
Compiles and builds properly for MIMXRT1060_EVK and MIMXRT1064_EVK, but not
tested lacking suitable boards.

Tested functions are:
- ping works bothway
- simple UDP transfer works bothway
- ntptime works
- the ftp server works
- secure socker works
- telnet and webrepl works

The MAC address is 0x02 plus 5 bytes from the manifacturing info field,
which can be considered as unique per device.

Some boards do not wire the RESET and INT pin of the PHY transceiver.  For
operation, these are not required.  If they are defined, they will be used.

This commit adds full support for a filesystem on all boards, with a block
device object mimxrt.Flash() and uos.VfsLfs2 enabled.

Main changes are:
- Refactoring of linker scripts to accomodate reserved area for VFS.  VFS
  will take up most of the available flash. 1M is reserved for code.  9K is
  reserved for flash configuration, interrupts, etc.
- Addition of _boot.py with filesystem init code, called from main.c.
- Definition of the mimxrt module with a Flash class in modmimxrt.[ch].
- Implementation of a flash driver class in mimxrt_flash.c.  All flashing
  related functions are stored in ITCM RAM.
- Addition of the uos module with filesystem functions.
- Implementation of uos.urandom() for the sake of completeness of the uos
  module.

It uses sample code from CircuitPython supplied under MIT license, which
uses the NXP SDK example code.

Done in collaboration with Philipp Ebensberger aka @alphaFred who
contributed the essential part to enable writing to flash while code is
executing, among other things.
