40cc7ec677 stm32/mpconfigport.h: Use IRQ_PRI_PENDSV to protect bluetooth ringbuf.
The default protection for the BLE ringbuf is to use
MICROPY_BEGIN_ATOMIC_SECTION, which disables all interrupts. On stm32 it
only needs to disable the lowest priority IRQ, pendsv, because that's the
IRQ level at which the BLE stack is driven.

8ce69288e9 extmod/modbluetooth: Remove limit on data coming from gattc data input.
This removes the limit on data coming in from a BLE.gattc_read() request,
or a notify with payload (coming in to a central).  In both cases the data
coming in to the BLE callback is now limited only by the available data in
the ringbuf, whereas before it was capped at (default hard coded) 20 bytes.

d6e051082a extmod/modbluetooth: Simplify how BLE IRQ callback is scheduled.
Instead of enqueue_irq() inspecting the ringbuf to decide whether to
schedule the IRQ callback (if ringbuf is empty), maintain a flag that knows
if the callback is on the schedule queue or not.  This saves about 150
bytes of code (for stm32 builds), and simplifies all uses of enqueue_irq()
and schedule_ringbuf().

77b8f86a5e stm32/qstrdefsport.h: Remove unused qstrs and make USB ones conditional.
qstrs in this file are always included in all builds, even if not used
anywhere.  So remove those that are never needed, and make USB names
conditional on having USB enabled.

4318a6d755 py/objstringio: Slightly optimize stringio_copy_on_write for code size.
With the memcpy() call placed last it avoids the effects of registers
clobbering.  It's definitely effective in non-inlined functions, but even
here it is still making a small difference.  For example, on stm32, this
saves an extra `ldr` instruction to load `o->vstr` after the memcpy()
returns.

bc129f1b84 py/qstr: Raise exception in qstr_from_strn if str to intern is too long.
The string length being longer than the allowed qstr length can happen in
many locations, for example in the parser with very long variable names.
Without an explicit check that the length is within range (as done in this
patch) the code would exhibit crashes and strange behaviour with truncated
strings.

d8057c325a stm32/storage: Change storage_read/write_blocks to return int type.
And return -MP_EIO if calling storage_read_block/storage_write_block fails.
This lines up with the return type and value (negative for error) of the
calls to MICROPY_HW_BDEV_READBLOCKS (and WRITEBLOCKS, and BDEV2 versions).

c169094f61 stm32/storage: Make pyb.Flash configurable, and support ext block proto.
The pyb.Flash() class can now be used to construct objects which reference
sections of the flash storage, starting at a certain offset and going for a
certain length.  Such objects also support the extended block protocol.
The signature for the constructor is: pyb.Flash(start=-1, len=-1).

7723dac337 stm32: Generalise flash mounting code so it supports arbitrary FS.
This commit refactors and generalises the boot-mount routine on stm32 so
that it can mount filesystems of arbitrary type.  That is, it no longer
assumes that the filesystem is FAT.  It does this by using mp_vfs_mount()
which does auto-detection of the filesystem type.

e873d352ad extmod/modbluetooth: Simplify management of pre-allocated event data.
The address, adv payload and uuid fields of the event are pre-allocated by
modbluetooth, and reused in the IRQ handler.  Simplify this and move all
storage into the `mp_obj_bluetooth_ble_t` instance.

This now allows users to hold on to a reference to these instances without
crashes, although they may be overwritten by future events.  If they want
to hold onto the values longer term they need to copy them.

fbb7646e3b stm32/nimble_hci_uart.c: Prevent scheduler running during CYW-BT wakeup.
Using mp_hal_delay_ms allows the scheduler to run, which might result in
another transmit operation happening, which would bypass the sleep (and
fail).  Use mp_hal_delay_us instead.

799b6d1e0c extmod: Consolidate FAT FS config to MICROPY_VFS_FAT across all ports.
This commit removes the Makefile-level MICROPY_FATFS config and moves the
MICROPY_VFS_FAT config to the Makefile level to replace it.  It also moves
the include of the oofatfs source files in the build from each port to a
central place in extmod/extmod.mk.

For a port to enabled VFS FAT support it should now set MICROPY_VFS_FAT=1
at the level of the Makefile.  This will include the relevant oofatfs files
in the build and set MICROPY_VFS_FAT=1 at the C (preprocessor) level.
