fca2730ea0 lib/utils/pyexec: Remove obsolete LCD initialization.
This was added a long time ago in 75abee206d
when USB host support was added to the stm (now stm32) port, and when this
pyexec code was actually part of the stm port.  It's unlikely to work as
intended anymore.  If it is needed in the future then generic hook macros
can be added in pyexec.

b9a35bebf7 py/qstr.h: Remove QSTR_FROM_STR_STATIC macro.
It practically does the same as qstr_from_str and was only used in one
place, which should actually use the compile-time MP_QSTR_XXX form for
consistency; qstr_from_str is for runtime strings only.

47d02b3104 extmod/nimble: Improve the flow control for l2cap recv path.
If the _IRQ_L2CAP_RECV handler does the actual consumption of the incoming
data (i.e. via l2cap_recvinto), rather than setting a flag for
non-scheduler-context to handle it later, then two things can happen:

- It can starve the VM (i.e. the scheduled task never terminates).  This is
  because calling l2cap_recvinto will empty the rx buffer, which will grant
  more credits to the channel (an HCI command), meaning more data can
  arrive.  This means that the loop in hal_uart.c that keeps reading HCI
  data from the uart and executing NimBLE events as they are created will
  not terminate, preventing other VM code from running.

- There's no flow control (i.e. data will arrive too quickly).  The channel
  shouldn't be given credits until after we return from scheduler context.

It's preferable that no work is done in scheduler/IRQ context.  But to
prevent this being a problem this commit changes l2cap_recvinto so that if
it is called in IRQ context, and the Python handler empties the rx buffer,
then don't grant credits until the Python handler is complete.

0f9a9129da stm32/rfcore: Fix flow control for IPCC RX IRQ.
Don't clear the IPCC channel flag until we've actually handled the incoming
data, or else the wireless firmware may clobber the IPCC buffer if more
data arrives.  This requires masking the IRQ until the data is handled.

469345e728 rp2: Add new port to Raspberry Pi RP2 microcontroller.
This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040
microcontroller.

The build system uses pure cmake (with a small Makefile wrapper for
convenience).  The USB driver is TinyUSB, and there is a machine module
with most of the standard classes implemented.  Some examples are provided
in the examples/rp2/ directory.

Work done in collaboration with Graham Sanderson.

d1945cc2b5 stm32/main: Check block 0 and 1 when auto-detecting littlefs.
The superblock for littlefs is in block 0 and 1, but block 0 may be erased
or partially written, so block 1 must be checked if block 0 does not have a
valid littlefs superblock in it.

Prior to this commit, if block 0 did not contain a valid littlefs
superblock (but block 1 did) then the auto-detection would fail, mounting a
FAT filesystem would also fail, and the system would reformat the flash,
even though it may have contained a valid littlefs filesystem.  This is now
fixed.

342dc61784 cc3200/ftp: Add quotes to PWD response and allow FEAT prior to login.
This commit improves some FTP implementation details for better
compatibility with FTP clients:

* The PWD command now puts quotes around the directory name before
  returning it.  This fixes BBEdit’s FTP client, which performs a PWD after
  each CWD and gets confused if the returned directory path is not
  surrounded by quotes.

* The FEAT command is now allowed before logging in. This fixes the lftp
  client, which send FEAT first and gets confused (tries to use TLS) if the
  server responds with 332.

c6f334272a stm32/mboot: Add support for signed and encrypted firmware updates.
This commit adds support to stm32's mboot for signe, encrypted and
compressed DFU updates.  It is based on inital work done by Andrew Leech.

The feature is enabled by setting MBOOT_ENABLE_PACKING to 1 in the board's
mpconfigboard.mk file, and by providing a header file in the board folder
(usually called mboot_keys.h) with a set of signing and encryption keys
(which can be generated by mboot_pack_dfu.py).  The signing and encryption
is provided by libhydrogen.  Compression is provided by uzlib.  Enabling
packing costs about 3k of flash.

The included mboot_pack_dfu.py script converts a .dfu file to a .pack.dfu
file which can be subsequently deployed to a board with mboot in packing
mode.  This .pack.dfu file is created as follows:
- the firmware from the original .dfu is split into chunks (so the
  decryption can fit in RAM)
- each chunk is compressed, encrypted, a header added, then signed
- a special final chunk is added with a signature of the entire firmware
- all chunks are concatenated to make the final .pack.dfu file

The .pack.dfu file can be deployed over USB or from the internal filesystem
on the device (if MBOOT_FSLOAD is enabled).

See #5267 and #5309 for additional discussion.

108183fcc0 tests/misc/sys_settrace: Make test output independent of invoked path.
The original logic of reducing a full path to a relative one assumes
"tests/misc" is in the filename which is limited in usage: it never works
for CPython on Windows since that will use a backslash as path separator,
and also won't work when the filename is a path not relative to the tests
directory which happens for example in the common case of running
"./run-tests -d misc".

Fix all cases by printing only the bare filename, which requires them all
to start with sys_settrace_ hence the renaming.
