Damien George 019dd84af1 extmod/modlwip: Register TCP close-timeout callback before closing PCB.
In d5f0c87bb9 this call to tcp_poll() was
added to put a timeout on closing TCP sockets.  But after calling
tcp_close() the PCB may be freed and therefore invalid, so tcp_poll() can
not be used at that point.  As a fix this commit calls tcp_poll() before
closing the TCP PCB.  If the PCB is subsequently closed and freed by
tcp_close() or tcp_abort() then the PCB will not be on any active list and
the callback will not be executed, which is the desired behaviour (the
_lwip_tcp_close_poll() callback only needs to be called if the PCB remains
active for longer than the timeout).

Damien George 734ada3e29 extmod/modlwip: Free any incoming bufs/connections before closing PCB.
Commit 2848a613ac introduced a bug where
lwip_socket_free_incoming() accessed pcb.tcp->state after the PCB was
closed.  The state may have changed due to that close call, or the PCB may
be freed and therefore invalid.  This commit fixes that by calling
lwip_socket_free_incoming() before the PCB is closed.

Damien George 883e987b90 esp32/modsocket: Raise EAGAIN when accept fails in non-blocking mode.
EAGAIN should be for pure non-blocking mode and ETIMEDOUT for when there is
a finite (but non-zero) timeout enabled.

Andrew Leech 1470184bdd stm32/sdram: Update MPU settings to block invalid region, change attrs.
Set the active MPU region to the actual size of SDRAM configured and
invalidate the rest of the memory-mapped region, to prevent errors due to
CPU speculation.  Also update the attributes of the SDRAM region as per ST
recommendations, and change region numbers to avoid conflicts elsewhere in
the codebase (see eth usage).

Paul Sokolovsky c4a6d9c631 zephyr: Switch back to enabling I2C in board-specific configs.
I2C can't be enabled in prj_base.conf because it's a board-specific
feature.  For example, if a board doesn't have I2C but CONFIG_I2C=y then
the build will fail (on Zephyr build system side).  The patch here gets the
qemu_cortex_m3 build working again.

Sebastien Rinsoz 6cf4e9675b py/mkrules.mk: Remove unnecessary ; in makefile.
This ; make Windows compilation fail with GNU makefile 4.2.1.  It was added
in 0dc85c9f86 as part of a shell if-
statement, but this if-statement was subsequently removed in
23a693ec2d so the semicolon is not needed.

this, for example, Windows users can specify the path of touch.exe.

Glenn Ruben Bakke 85bde0889d lib/nrfx: Upgrade nrfx to master.
Updating the nrfx git submodule containing HAL drivers for nrf-port
from v1.3.1 to current master. The version pointed to is one commit
ahead of v1.7.1 release. The extra commit contains a bugfix for
nrfx_uart_tx_in_progress() making it report correctly.

The general upgrade of nrfx is considered to be safe, as almost all
changes in between 1.3.1 and 1.7.1 are related to peripherals and
target devices not used by the nrf-port as of today.

stijn fb54736bdb py/objarray: Add decode method to bytearray.
Reuse the implementation for bytes since it works the same way regardless
of the underlying type.  This method gets added for CPython compatibility
of bytearray, but to keep the code simple and small array.array now also
has a working decode method, which is non-standard but doesn't hurt.

Damien George c769da1aaa stm32/i2c: Support setting the I2C TIMINGR value via keyword arg.
On MCUs that have an I2C TIMINGR register, this can now be explicitly set
via the "timingr" keyword argument to the I2C constructor, for both
machine.I2C and pyb.I2C.  This allows to configure precise timing values
when the defaults are inadequate.

Andrew Leech ed2b6ea0a8 stm32/i2c: Make timeout for hardware I2C configurable.
Previously the hardware I2C timeout was hard coded to 50ms which isn't
guaranteed to be enough depending on the clock stretching specs of the I2C
device(s) in use.

This patch ensures the hardware I2C implementation honors the existing
timeout argument passed to the machine.I2C constructor.  The default
timeout for software and hardware I2C is now 50ms.

Damien George b10d0664be extmod/machine_i2c: Add i2c.writevto() that can write a vector of bufs.
For example: i2c.writevto(addr, (buf1, buf2)).  This allows to efficiently
(wrt memory) write data composed of separate buffers, such as a command
followed by a large amount of data.

        uint16_t addr,
        size_t n,
        mp_machine_i2c_buf_t *bufs,
        unsigned int flags

Damien George 8bec0e869d docs/machine.I2C: Add writevto method to write a vector of byte bufs.
This allows to efficiently send to an I2C slave data that is made up of
more than one buffer.  Instead of needing to allocate temporary memory to
combine buffers together this new method allows to pass in a tuple or list
of buffers.  The name is based on the POSIX function writev() which has
similar intentions and signature.

The reasons for taking this approach (compared to having an interface with
separate start/write/stop methods) are:
- It's a backwards compatible extension.
- It's convenient for the user.
- It's efficient because there is only one Python call, then the C code can
  do everything in one go.
- It's efficient on the I2C bus because the implementation can do
  everything in one go without pauses between blocks of bytes.
- It should be possible to implement this extension in all ports, for
  hardware and software I2C.

Further discussion is found in issue #3482, PR #4020 and PR #4763.

Damien George e1e3704aa1 stm32/modmachine: Create dedicated asm function to branch to bootloader.
Recent gcc versions (at least 9.1) give a warning about using "sp" in the
clobber list.  Such code is removed by this patch.  A dedicated function is
instead used to set SP and branch to the bootloader so the code has full
control over what happens.

Fixes issue #4785.

Damien George 0557f0b74b esp32/network_ppp: Add a timeout for closing PPP connection.
This also fixes deleting the PPP task, since eTaskGetState() never returns
eDeleted.

A limitation with this patch: once the PPP is deactivated (ppp.active(0))
it cannot be used again. A new PPP instance must be created instead.
