887486582e nrf: Remove port-specific help
It contains mentions to the pyb module which was removed.
The ble-specific help will be re-added later when the API
is stabilized.

ec7982ec6d stm32/mboot: Add support for erase/read/write of external SPI flash.
This patch adds support to mboot for programming external SPI flash.  It

that internal MCU flash is programmed.

7f41f73f0f stm32/qspi: Don't require data reads and writes to be a multiple of 4.
Prior to this patch the QSPI driver assumed that the length of all data
reads and writes was a multiple of 4.  This patch allows any length.  Reads
are optimised for speed by using 32-bit transfers when possible, but writes
always use a byte transfer because they only use a single data IO line and
are relatively slow.

e49cd106b4 stm32/spi: Fix SPI driver so it can send/recv more than 65535 bytes.
The DMA peripheral is limited to transferring 65535 elements at a time so
in order to send more than that the SPI driver must split the transfers up.

The user must be aware of this limit if they are relying on precise timing
of the entire SPI transfer, because there might be a small delay between
the split transfers.

Fixes issue #3851, and thanks to @kwagyeman for the original fix.

It's possible (at least on F4 MCU's) to have RXNE and STOPF set at the same

2fbab8067a Prevent freezing USB during high frequency PulseIn.
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

Fixes #516 and #876

24c416cc66 stm32/mboot: Increase USB rx_buf and DFU buf sizes to full 2048 bytes.
The DFU USB config descriptor returns 0x0800=2048 for the supported
transfer size, and this applies to both TX (IN) and RX (OUT).  So increase
the rx_buf to support this size without having a buffer overflow on
received data.

With this patch mboot in USB DFU mode now works with dfu-util.

039f196c56 esp32/modnetwork: Fix isconnected() when using static IP config.
Currently <WLAN>.isconnected() always returns True if a static IP is set,
regardless of the state of the connection.

This patch introduces a new flag 'wifi_sta_connected' which is set in
event_handler() when GOT_IP event is received and reset when DISCONNECTED
event is received (unless re-connect is successful).  isconnected() now
simply returns the status of this flag (for STA_IF).

The pre-existing flag misleadingly named 'wifi_sta_connected" is also
renamed to 'wifi_sta_connect_requested'.

190c7dba89 stm32/mpconfigport.h: Enable DELATTR_SETATTR and BUILTINS_NOTIMPLEMENTED
MICROPY_PY_DELATTR_SETATTR can now be enabled without a performance hit for
classes that don't use this feature.

MICROPY_PY_BUILTINS_NOTIMPLEMENTED is a minor addition that improves
compatibility with CPython.

93150a0d40 ports: Enable descriptors on stm32, esp8266, esp32 ports.
They are now efficient (in runtime performance) and provide a useful
feature that's hard to obtain without them enabled.

fadd6bbe43 unix/moduos_vfs: Add missing uos functions from traditional uos module.
Now that the coverage build has fully switched to the VFS sub-system these
functions were no longer available, so add them to the uos_vfs module.

Also, vfs_open is no longer needed, it's available as the built-in open.

1d40f12e44 unix: Support MICROPY_VFS_POSIX and enable it in coverage build.
The unix coverage build is now switched fully to the VFS implementation, ie
the uos module is the uos_vfs module.  For example, one can now sandbox uPy
to their home directory via:

    $ ./micropython_coverage

    >>> import uos
    >>> uos.umount('/') # unmount existing root VFS
    >>> vfs = uos.VfsPosix('/home/user') # create new POSIX VFS
    >>> uos.mount(vfs, '/') # mount new POSIX VFS at root

Some filesystem/OS features may no longer work with the coverage build due
to this change, and these need to be gradually fixed.

The standard unix port remains unchanged, it still uses the traditional uos
module which directly accesses the underlying host filesystem.
