This commit creates a new stm32 board for the NUCLEO_H743ZI2, which is the
current version of this from ST. This is a modified copy of the
NUCLEO_H743ZI board, and the ZI2 board differs in a few minor ways:
- LED2 has moved from PB7 to PE1 and is now yellow rather than blue
- the USB power enable has moved from PG6 to PG10
- the USER button is now pulled down
This function can be used to enable and disable the DC/DC converter with or
without the Bluetooth stack enabled. It can also be used to query the
current state of the DC/DC.
This commit also adds a definition of ARRAY_SIZE needed by nrfx HAL-layer.
extmod/vfs_lfs.c needs to resolve `mp_hal_time_ns()` in order to calculate
a timestamp from 1970 epoch. A wall clock is not available in the nrf
port, hence the function is implemented to resolve compilation linkage
error. The function always return 0.
Set the default manifest to "modules/manifest.py". This includes files
from the folder "modules/scripts". The manifest default value is overriden
by all nrf51 boards that have SoftDevice present (SD=s110) to save flash.
Also add "modules/manifest.py" which is set to freeze
"modules/scripts/_mkfs.py".
Add a helper script _mkfs.py which automatically formats the file system if
nrf.Flash() is located and a VFS file system has been included in the
compilation.
The precedence is: first LFS1, LFS2 then FAT.
Update the Makefile to handle FROZEN_MANIFEST, and the README with some
small samples on how to use freeze manifests. And add BOARD_DIR to the
Makefile which can be referenced in boards/<board>/mpconfigboard.mk to
include a board specific manifest.
Enable the following features for all boards except
nrf51 boards with SoftDevice present:
- MICROPY_VFS
- MICROPY_PY_NRF
- MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE
Add posibility to override linker script "_fs_size" from make by adding the
FS_SIZE parameter. The syntax of value is linker script syntax. For
example, the value of 131072 bytes can be written as 128K like this:
FS_SIZE=128K.
If not set, default value for "_fs_size" from linker script will be used.
Disable MICROPY_FATFS_MULTI_PARTITION configuration because there is no
partition table in the flash for FATFS to read.
Also, set MICROPY_FATFS_MAX_SS to the size of a flash page. For nrf51 the
value 1024 is set. For nrf52/nrf91 the value 4096 is set.
This documents parameters that can be passed to make to enable a specific
file system to included in the build. Also, document the Makefile override
parameter "FS_SIZE" that can be used to tune the size of the flash region
to use as internal flash file system.
Update flash.c to also be compiled in when
MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE is enabled and SoftDevice is
present.
Update bluetooth/ble_drv.c to forward flash events to flash.c when
MICROPY_HW_ENABLE_INTERNAL_FLASH_STORAGE is enabled.
This commit adds the "nrf" module for port specific modules and objects.
Included in it is the "Flash" object which exposes a block device
implementation to access internal SoC flash.
Thanks to @aykevl aka Ayke van Laethem for the initial implementation.
Calculate the unused flash area on the target device. The values will be
exposed by _unused_flash_start and _unused_flash_length. The start address
and the length are not aligned to either word or pages.
This allows changing the frequency to: 100kHz, 200kHz, 400kHz, 800kHz,
1MHz, 2MHz, 4MHz, 8MHz, 16MHz, 32MHz, 64MHz. For frequencies 2MHz and
below, low power run (LPR) mode is enabled automatically.

For consistency with other board-level config macros that begin with
MICROPY_HW_USB.
Also allow boards in the mimxrt, nrf and samd ports to configure these
values.

Commit 4173950658 removed automatic building
of mpy-cross, which rebuilt it whenever any of its dependent source files
changed.
But needing to build mpy-cross, and not knowing how, is a frequent issue.
This commit aims to help by automatically building mpy-cross only if it
doesn't exist. For Makefiles it uses an order-only prerequisite, while
for CMake it uses a custom command.
If MICROPY_MPYCROSS (which is what makemanifest.py uses to locate the
mpy-cross executable) is defined in the environment then automatic build
will not be attempted, allowing a way to prevent this auto-build if needed.
Thanks to Trammell Hudson aka @osresearch for the original idea; see #5760.

Optionally enabled via MICROPY_PY_UJSON_SEPARATORS. Enabled by default.
For dump, make sure mp_get_stream_raise is called after
mod_ujson_separators since CPython does it in this order (if both
separators and stream are invalid, separators will raise an exception
first).
Add separators argument in the docs as well.

Reverse operations are supported on stm32 and rp2, and esp32 has enough
space to also enable inplace operations, to make it complete.

This enables optional support for the hardware UART to use the RTS and/or
CTS pins for flow control.
The new "flow" constructor keyword specifies a bitmask of RTS and/or CTS.
This matches the interface used by machine.UART on stm32 and rp2.
Previously on ESP32 it was possible to specify which pins to use for the
RTS and CTS signals, but hardware flow control was never functional: CTS
was not checked before transmitting bytes, and RTS was always driven high
(signalling no buffer space available). With this patch, CTS and RTS both
operate as expected.
This also includes an update to the machine.UART documentation.

Commit e33bc597 ("py: Remove calls to file reader functions when these
are disabled.") changed the condition for one caller of
do_execute_raw_code() from
MICROPY_PERSISTENT_CODE_LOAD
to
MICROPY_HAS_FILE_READER && MICROPY_PERSISTENT_CODE_LOAD
The condition that enables compiling the function itself needs to be
changed to match.
