172a031dff rp2/boards/PIMORONI_PICOLIPO_16MB: Fix 16MB flash size.
Was incorrectly added as 7MB for an 8MB SPI flash, but this board has a
16MB chip, not 8MB, so it should be 15MB leaving 1MB for MicroPython.

Thanks to @robert-hh

0a9335ecaa rp2/rp2_pio: Support exec with sideset.
The rp2.StateMachine.exec errors when supplying a sideset action.  This
commit passes the sideset_opt from the StateMachine though to the parser.
It also adds some value validation to the sideset operator.

Additionally, the "word" method is added to the exec to allow any other
unsupported opcodes.

Fixes issue #7924.

83827e8e63 stm32/uart: Fix race conditions and clearing status in IRQ handler.
Prior to this commit IRQs on STM32F4 could be lost because SR is cleared by
reading SR then reading DR.  For example, if both RXNE and IDLE IRQs were
active upon entry to the IRQ handler, then IDLE is lost because the code
that handles RXNE comes first and accidentally clears SR (by reading SR
then DR to get the incoming character).

This commit fixes this problem by making the IRQ handler more atomic in the
following operations:
- get current IRQ status flags
- deal with RX character
- clear remaining status flags
- call user handler

On the STM32F4 it's very hard to get this right because the only way to
clear IRQ status flags is to read SR then DR, but the read of DR may read
some data which should remain in the register until the user wants to read
it.  And it won't work to cache the read because RTS/CTS flow control will
then not work.  So instead the new code disables interrupts if the DR is
full and waits for the user to read it before reenabling the interrupts.

Fixes issue mentioned in #4599 and #6082.

c2e4759cfa mimxrt/modmachine: Implement machine.WDT() and machine.reset_cause().
The API follows that of rp2, stm32, esp32, and the docs.

    wdt=machine.WDT(0, timeout)

        Timeout is given in ms. The valid range is 500 to 128000 (128
        seconds) with 500 ms granularity. Values outside of that range will
        be silently aligned.

    wdt.feed()

        Resets the watchdog timer (feeding).

    wdt.timeout_ms(value)

        Sets a new timeout and feeds the watchdog.

        This is a new, preliminary method which is not yet documented.

    reset_cause = machine.reset_cause()

        Values returned:

        1  Power On reset
        3  Watchdog reset
        5  Software reset: state after calling machine.reset()

More elaborate API functions are supported by the MCU, like an interrupt
called a certain time after feeding.  But for port cosistency that is not
implemented.

1866ed7e2e mimxrt/eth: Add LAN support and integrate the network module.
This commit implements 10/100 Mbit Ethernet support in the mimxrt port.

The following boards are configured without ETH network:
- MIMXRT1010_EVK
- Teensy 4.0

The following boards are configured with ETH network:
- MIMXRT1020_EVK
- MIMXRT1050_EVK
- MIMXRT1060_EVK
- MIMXRT1064_EVK
- Teensy 4.1

Ethernet support tested with TEENSY 4.1, MIMRTX1020_EVK and MIMXRT1050_EVK.
Build tested with Teensy 4.0 and MIMXRT1010_EVK to be still working.
Compiles and builds properly for MIMXRT1060_EVK and MIMXRT1064_EVK, but not
tested lacking suitable boards.

Tested functions are:
- ping works bothway
- simple UDP transfer works bothway
- ntptime works
- the ftp server works
- secure socker works
- telnet and webrepl works

The MAC address is 0x02 plus 5 bytes from the manifacturing info field,
which can be considered as unique per device.

Some boards do not wire the RESET and INT pin of the PHY transceiver.  For
operation, these are not required.  If they are defined, they will be used.

549448e8bb esp32: Enable optimisations and move code to iRAM to boost performance.
This commit enables some significant optimisations for esp32:
- move the VM to iRAM
- move hot parts of the runtime to iRAM (map lookup, load global/name,
  mp_obj_get_type)
- enable MICROPY_OPT_LOAD_ATTR_FAST_PATH
- enable MICROPY_OPT_MAP_LOOKUP_CACHE
- disable assertions
- change from -Os to -O2 for compilation

It's hard to measure performance on esp32 due to external flash and
hardware caching.  But this set of changes improves performance compared to
master by (on a TinyPICO with the GENERIC build, using IDF 4.2.2, running
at 160MHz):

viper_call2b.py      173.76 ->     209.42 :   +35.66 = +20.523% (+/-0.00%)

Five tests have more than 3x speed up (200%+).

The performance of the tests bm_fft, bm_pidigits and misc_aes now scale
with CPU frequency (eg changing frequency to 240MHz boosts the performance
of these by 50%), which means they are no longer influenced by timing of
external flash access.  (The viper_call* tests did previously scale with
CPU frequency, and they still do.)

Turning off assertions reduces code size by about 80k, and going from -Os
to -O2 costs about 100k, so the net change in code size (for the GENERIC
board) is about +20k.

If a board wants to enable assertions, or use -Os instead of -O2, that's
still possible by overriding the sdkconfig parameters.

eea6cd85b3 stm32/sdram: Enforce gcc opt, and use volatile and DSB in sdram_test.
Ensures consistent behaviour and resolves the D-Cache bug (the "exhaustive"
argument being lost due to cache being turned off) when O0 is used.

The changes in this commit are:

- Change -O0 to -Os because "gcc is considered broken at -O0" according to
  https://github.com/ARM-software/CMSIS_5/issues/620#issuecomment-550235656

- Use volatile for mem_base so the compiler doesn't optimise away reads or
  writes to the SDRAM, which is being tested.

- Use DSB to prevent any other compiler optimisations that would change the
  testing logic.

- Use alternating pattern/antipattern in exhaustive test to catch more
  hardware/configuration errors.

Implementation adapted by @andrewleech, taken directly from investigation
by @iabdalkader and @dpgeorge.

See #7841 and #7869 for further discussion.

f046b50ca5 esp32/main: Add option for a board to hook code into startup sequence.
To do this the board must define MICROPY_BOARD_STARTUP, set
MICROPY_SOURCE_BOARD then define the new start-up code.

For example, in mpconfigboard.h:

    #define MICROPY_BOARD_STARTUP board_startup
    void board_startup(void);

in mpconfigboard.cmake:

    set(MICROPY_SOURCE_BOARD
        ${MICROPY_BOARD_DIR}/board.c
    )

and in a new board.c file in the board directory:

    #include "py/mpconfig.h"

    void board_startup(void) {
        boardctrl_startup();
        // extra custom startup
    }

This follows stm32's boardctrl facilities.

This commit allows using all the available PWM timers (up to 8) and
channels (up to 16), without affecting the PWM API.

If a new frequency is set, first it checks if another timer is using the
same frequency.  If yes, then it uses this timer, otherwise, it creates a
new one.  If all timers are used, the user should set an already used
frequency, or de-init a channel.

6e39f2cc1e stm32/boards: Add OLIMEX H407 board definition.
This change adds the OLIMEX H407 support to the STM32 port.  The H407
(https://www.olimex.com/Products/ARM/ST/STM32-H407/) is simliar to the
already existing E407
(https://www.olimex.com/Products/ARM/ST/STM32-E407) but does not support
Ethernet and has a full-size USB-A port instead of a Mini-USB socket.

Both boards use the STM32F407ZGT6 CPU.

This port is basically a copy of the E407 but with changed pinmux:
* Removed Ethernet pin definition
* Removed UART1 (pins are used for other functions)
* Removed UART3 flow control pins (pins are used for other functions)
* Removed SD-Card detect pin (since it is not connected on the H407)

A REPL on UART3 is connected to the U3BOOT-header, a 3-pin header with RX,
TX and GND that is intended for the serial terminal.

Tested:
* Micro-SD Card is detected when inserted on RESET
* REPL on UART3 works
* Serial port on the mini USB socket

b326edf68c all: Remove MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE.
This commit removes all parts of code associated with the existing
MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE optimisation option, including the
-mcache-lookup-bc option to mpy-cross.

This feature originally provided a significant performance boost for Unix,
but wasn't able to be enabled for MCU targets (due to frozen bytecode), and
added significant extra complexity to generating and distributing .mpy
files.

The equivalent performance gain is now provided by the combination of
MICROPY_OPT_LOAD_ATTR_FAST_PATH and MICROPY_OPT_MAP_LOOKUP_CACHE (which has
been enabled on the unix port in the previous commit).

It's hard to provide precise performance numbers, but tests have been run
on a wide variety of architectures (x86-64, ARM Cortex, Aarch64, RISC-V,
xtensa) and they all generally agree on the qualitative improvements seen
by the combination of MICROPY_OPT_LOAD_ATTR_FAST_PATH and
MICROPY_OPT_MAP_LOOKUP_CACHE.

For example, on a "quiet" Linux x64 environment (i3-5010U @ 2.10GHz) the
change from CACHE_MAP_LOOKUP_IN_BYTECODE, to LOAD_ATTR_FAST_PATH combined
with MAP_LOOKUP_CACHE is:

misc_pystone.py    83860.10 ->   82592.56 :  -1267.54 =  -1.511% (+/-2.27%)
misc_raytrace.py   21490.40 ->   22227.23 :   +736.83 =  +3.429% (+/-1.88%)

This shows that the new optimisations are at least as good as the existing
inline-bytecode-caching, and are sometimes much better (because the new
ones apply caching to a wider variety of map lookups).

The new optimisations can also benefit code generated by the native
emitter, because they apply to the runtime rather than the generated code.
The improvement for the native emitter when LOAD_ATTR_FAST_PATH and
MAP_LOOKUP_CACHE are enabled is (same Linux environment as above):

misc_raytrace.py   19800.01 ->   23350.73 :  +3550.72 = +17.933% (+/-2.79%)

In summary, compared to MICROPY_OPT_CACHE_MAP_LOOKUP_IN_BYTECODE, the new
MICROPY_OPT_LOAD_ATTR_FAST_PATH and MICROPY_OPT_MAP_LOOKUP_CACHE options:
- are simpler;
- take less code size;
- are faster (generally);
- work with code generated by the native emitter;
- can be used on embedded targets with a small and constant RAM overhead;
- allow the same .mpy bytecode to run on all targets.

See #7680 for further discussion.  And see also #7653 for a discussion
about simplifying mpy-cross options.
