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.

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.

The QR decoder has a single item that is 8908 bytes big and placed
on the stack. (struct datastream)
Without enlarging the stack, this will reliably crash.
Call `supervisor.disable_ble_workflow()` and the BLE workflow will
be disabled until the chip is reset.
This also includes a couple fixes:
1. Terminals can now be deinit by setting the tilegrid to NULL. This
prevents using the tilegrid before display is init.
2. Fix BLE serial send amount when sending more than a single packet.
Fixes#5049
