This targets the 64-bit CPU Raspberry Pis. The BCM2711 on the Pi 4
and the BCM2837 on the Pi 3 and Zero 2W. There are 64-bit fixes
outside of the ports directory for it.
There are a couple other cleanups that were incidental:
* Use const mcu_pin_obj_t instead of omitting the const. The structs
themselves are const because they are in ROM.
* Use PTR <-> OBJ conversions in more places. They were found when
mp_obj_t was set to an integer type rather than pointer.
* Optimize submodule checkout because the Pi submodules are heavy
and unnecessary for the vast majority of builds.
Fixes#4314
This is to make the builds for all nucleo/discovery boards uniform, so they
can be treated the same by the auto build scripts.
The CI script is updated to explicitly enable mboot and packing, to test
these features.

This prevents SPI4/5 from being used if SDIO and CYW43 are enabled, because
the DMA for the SDIO is used on an IRQ and must be exclusivly available for
use by the SDIO peripheral.

Because DMA2 may be in use by other peripherals, eg SPI1.
On PYBD-SF6 it's possible to trigger a bug in the existing code by turning
on WLAN and connecting to an AP, pinging the IP address from a PC and
running the following code on the PYBD:
def spi_test(s):
while 1:
s.write('test')
s.read(4)
spi_test(machine.SPI(1,100000000))
This will eventually fail with `OSError: [Errno 110] ETIMEDOUT` because
DMA2 was turned off by the CYW43 driver during the SPI1 transfer.
This commit fixes the bug by removing the code that explicitly disables
DMA2. Instead DMA2 will be automatically disabled after an inactivity
timeout, see commit a96afae90f6e5d693173382561d06e583b0b5fa5

Quail (https://www.mikroe.com/quail, PID: MIKROE-1793) is based on an
STM32F427VI CPU, featuring 2048 kB of Flash memory and 192 kB of RAM. An
on-board Cypress S25FL164K adds 8 MB of SPI Flash.
Quail has 4 mikroBUS(TM) sockets for Mikroe click(TM) board connectivity,
along with 24 screw terminals for connecting additional electronics and two
USB ports (one for programming, the other for external mass storage).
4 UARTs, 2 SPIs and 1 I2C bus are available for communication.

Was incorrectly added as 7MB for an 8MB SPI flash, but this board has a
16MB chip, not 8MB, so it should be 15MB leaving 1MB for MicroPython.

The rp2.StateMachine.exec errors when supplying a sideset action. This
commit passes the sideset_opt from the StateMachine though to the parser.
It also adds some value validation to the sideset operator.
Additionally, the "word" method is added to the exec to allow any other
unsupported opcodes.
Fixes issue #7924.
- Makefile: update to use new ASF4 files, support frozen manifest, and
include source files in upcoming commits
- boards/manifest.py: add files to freeze
- boards/samd51p19a.ld: add linker script for this MCU
- help.c: add custom help text
- main.c: execute _boot.py, boot.py and main.py on start-up
- modules/_boot.py: startup file to freeze
- modutime.c: add gmtime, localtime, mktime, time functions
- mpconfigport.h: enabled more features for sys and io and modules
- mphalport.h: add mp_hal_pin_xxx macros
- mphalport.c: add mp_hal_stdio_poll
Don't force the 'HAL' string to be part of the platform string because
it doesn't have a sensible meaning for all possible platforms, and
swap it with the PLATFORM_ARCH string so the strings which most platforms
have come first.
Although the pyboard has only 4 LEDs, there are some boards that (may) have
more. This commit adds 2 more LEDs to the led.c file that if defined in
the board-specific config file will be compiled in.
- Add board.md files for MIMXRT1060_EVK and MIMXRT1064_EVK warning about
their experimental state.
- Add separate deploy_teensy.md and deploy_mimxrt.md files.
The ARCH MIX board exposes the Ethernet Pins at it's connectors. Therefore
the software is configured for using a LAN8720 PHY device. Breakout boards
with the LAN8720 are easily available.
