This is a best-effort implementation of write polling. It's difficult to
do correctly because if there are multiple output streams (eg UART and USB
CDC) then some may not be writeable while others are. A full solution
should also have a return value from mp_hal_stdout_tx_strn(), returning the
number of bytes written to the stream(s). That's also hard to define.
The renesas-ra and stm32 ports already implement a similar best-effort
mechanism for write polling.
Fixes issue #11026.

It keeps compatibility with the XIAO bootloader by:
- using Soft Device 7.3.0
- reserving 48k memory for the bootloader.
So on double reset a drive pops for uploading an uf2 image or a nrfutil zip
pkg file. Instructions to create it from a hex file are included. The
bootloader can as well be activated with the touch 1200 option of nrfutil.
The script download_ble_stack.sh has been adapted to get the version 7.3.0
soft device files. It may have to be executed once before building.
The file system is set to 256k and the pin definitions are adapted.
Besides that, it has the common functionality and omissions. The on-board
sensors and additional flash can be supported by Python scripts.
Some devices, such as the LightBlue BTLE app on iOS, try to use Bluetooth 5
when connecting to a device. This means that they will send a
BLE_GAP_EVT_PHY_UPDATE_REQUEST message to shift to a new physical layer.
If this event isn't handled, LightBlue (and likely other Bluetooth 5.0
central devices) will try to connect and then fail, staying in
"Connecting..." state forever. This message should be replied to with
sd_ble_gap_phy_update, as documented in
drivers/bluetooth/s140_nrf52_6.1.1/s140_nrf52_6.1.1_API/include/ble_gap.h.
This commit handles the event. LightBlue can now successfully connect to a
BTLE device on a P10059 nRF52840 dongle running MicroPython. Two other
related events have logging added in case they are needed in the future.
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.
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.

The last argument of TUD_CDC_DESCRIPTOR() is the endpoint size (or
wMaxPacketSize), not the CDC RX buffer size (which can be larger than the
endpoint size).

The mpconfigport.h file is an internal header and should only ever be
included once by mpconfig.h.

The storage space of the advertisement name is not declared static, leading
to a random advertisement name. This commit fixes the issue by declaring
it static.
The Bluetooth link gets disconnected when connecting from a PC after 30-40
seconds. This commit adds handling of the data length update request. The
data length parameter pointer is set to NULL in the reply, letting the
SoftDevice automatically set values and use them in the data length update
procedure.
mp_keyboard_interrupt() triggers a compiler error because the function is
implicitly declared. This commit adds "py/runtime.h" to the includes.
Fixes issue #5732.
Commit 6cea369b89 updated the TinyUSB
submodule to a version based on nrfx v2.0.0. This commit updates the nrf
port to work with the latest TinyUSB and nrfx v2.0.0.
The "random" module no longer uses the hardware RNG (the extmod version of
this module has a pseudo-random number generator), so the config option
MICROPY_PY_RANDOM_HW_RNG is no longer meaningful. This commit replaces it
with MICROPY_HW_ENABLE_RNG, which controls whether the hardware RNG is
included in the build.
If the exception doesn't need printf-style formatting then calling
mp_raise_msg is more efficient. Also shorten exception messages to match
style in core and other ports.
This patch add basic building blocks for nrf9P60.
It also includes a secure bootloader which forwards all
possible peripherals that are user selectable to become
non-secure. After configuring Flash, RAM and peripherals
the secure bootloader will jump to the non-secure domain
where MicroPython is placed.
The minimum size of a secure boot has to be a flash
block of 32Kb, hence why the linker scripts are
offsetting the main application this much.
The RAM offset is set to 128K, to allow for later
integration of Nordic Semiconductor's BSD socket
library which reserves the range 0x20010000 - 0x2001FFFF.
Add nrf-port finyusb driver files. USB CDC can be activated
by board configuration files using the MICROPY_HW_USB_CDC.
Updating BLE driver, Makefile, nrfx-glue and main.c to plug
in the tinyusb stack.
The the nrfx driver is aware of chip specific registers, while
the raw HAL abstraction is not. This driver enables use of NVMC
in non-secure domain for nrf9160.
Removing linker script for nrf52840 s140 v6.0.0 as pca10056
target board now points to the new v6.1.1. Also, removing the
entry from the download_ble_stack.sh script.
Removing linker script for nrf52832 s132 v6.0.0 as all target
boards now points to the new v6.1.1. Also, removing the entry
from the download_ble_stack.sh script.
This patch makes sure that the char_data.props is first
assigned a value before other flags are OR'd in.
Resolves compilation warning on possible unitialized variable.
This patch makes sure that advertisment data is located in
persistent static RAM memory throughout the advertisment.
Also, setting m_adv_handle to predifined
BLE_GAP_ADV_SET_HANDLE_NOT_SET value to indicate first time
usage of the handle. Upon first advertisment configuration
this will be populated with a handle value returned by the
stack (s132/s140).
Due to new webpages at nordicsemi.com, the download links
for Bluetooth LE stacks were broken.
This patch updates the links to new locations for the current
targets.
For s132 and s140, GAP_ADV_MAX_SIZE was currently set to
BLE_GATT_ATT_MTU_DEFAULT, which is 23. The correct value
should have been 31, but there are no define for this in
the s132/s140 header files as for s110.
Updating define in ble_drv.c to the correct value of 31.
Support added for s132/s140 v6 in linker scripts and boards.
Support removed for s132 v2/3/5.
Download script updated to fetch new stacks and removed the
non-supported ones.
ble_drv.c updated to only handle s110 v8, and s132/s140 v6.
ubluepy updated to continue scanning after each individual scan
report reported to the module to keep old behaviour of the
Scanner class.
