Jim Mussared 873bd00ad4 rp2: Rename PICO, PICO_W to RPI_PICO, RPI_PICO_W.
PICO might not always be a unique name across all ports, and the
convention generally for other boards is to do VENDOR_BOARD.

Jim Mussared 1a99f74063 ports/*/boards/*/board.json: Remove "id" field.
This was used to override the firmware filename generated by the build

Now we're making everything use the board definition name (i.e. the

Jim Mussared 45845acf6d rp2: Use uppercase variant names.
This is to support a future change to add the variant name to the build
directory and therefore should be the same style as the board name.

This only affects the WEACTSTUDIO board. Also standardises on a convention
for naming flash-size variants. Normally we would write e.g. 2MiB, but in
uppercase, it's awkward to write 2MIB, so instead use 2M, 512K, etc for
variant names, but use 2MiB when not constrained by case (e.g. a regular
filename).

Jim Mussared 9573d31071 all: Remove query-variants make target.
This is difficult to implement on cmake-based ports, and having the list
of variants in mpconfigboard.{cmake,mk} duplicates information that's
already in board.json.

This removes the existing query-variants make target from stm32 & rp2
and the definition of BOARD_VARIANTS from the various board files.

Also renames the cmake variable to MICROPY_BOARD_VARIANT to match other
variables such as MICROPY_BOARD. The make variable stays as
BOARD_VARIANT.

This commit:
- Finds a common set of board feature tags and maps existing features to

- Removes some less-useful board feature tags.
- Ensures all MCUs are specified correctly.
- Ensures all boards have a vendor (and fixes some vendor names).

This is to make the downloads page show a less intimidating set of filters.

robert-hh c02da6d81d rp2/machine_pin: Factor out pin-find code from machine_pin_make_new.
And use it in mp_hal_get_pin_obj() and machine_pin_make_new().  That way,
mp_hal_get_pin_obj() accepts both int and str objects as argument, allowing
use of a pin specifier instead of a pin object in the constructor of
devices which need a pin as parameter.

E.g. instead of

    uart = UART(0, tx=Pin(0), rx=Pin(1))

one can write:

    uart = UART(0, tx=0, rx=1)

Ondrej Wisniewski 29401a719f rp2/mphalport: Only use CYW43 MAC for WLAN0 interface.
Building the Pico-W needs the MICROPY_PY_NETWORK_CYW43 flag to be set in
order to include building the CYW43 Wifi driver.  But then mp_hal_get_mac()
handles the MAC assignment for all nics the "CYW43 way", copying the real
MAC provided by the WiFi hardware.  This will fail for all other NIC types,
resulting in an invalid MAC address.

The solution in this commit is to add a check for the NIC type parameter
idx and handle the MAC address respectively.

Adam Green f9958417d8 rp2: Make rp2_state_machine_exec accept integers.
Currently rp2.StateMachine.exec(instr_in) requires that the instr_in
parameter be a string representing the PIO assembly language instruction
to be encoded by rp2.asm_pio_encode(). This commit allows the parameter
to also be of integral type. This is useful if the exec() method is
being called often where the use of pre-encoded machine code is
desireable.

This commit still supports calls like:
    sm.exec("set(0, 1)")

It also now supports calls like:
    # Performed once earlier, maybe in __init__()
    assembled_instr = rp2.asm_pio_encode("out(y, 8)", 0)
    # Performed multiple times later as the PIO state machine is
    # configured for its next run.
    sm.exec(assembled_instr)

The existing examples/rp2/pio_exec.py and examples/rp2/pio_pwm.py that
exercise the rp2.StateMachine.exec() method still work with this change.

David (Pololu) bf3eb9dc39 rp2/machine_i2c: Add timeout parameter for machine.I2C().
This commit adds support for the `timeout` keyword argument to machine.I2C
on the rp2 port, following how it's done on other ports.

The main motivation here is avoid the interpreter crashing due to infinite
loops when SDA is stuck low, which is quite common if the board gets reset
while reading from an I2C device.

A default timeout of 50ms is chosen because it's consistent with:
- Commit a707fe50b0 which used a timeout of
  50,000us for zero-length writes on the rp2 port.
- The machine.SoftI2C class which uses 50,000us as the default timeout.
- The stm32 port's hardware I2C, which uses 50,000us for
  I2C_POLL_DEFAULT_TIMEOUT_US.

This commit also fixes the default timeout on the esp32 port to be
consistent with the above, and updates the documentation for machine.I2C to
document this keyword argument.

David Grayson c046b23ea2 shared/runtime/pyexec: Don't allow Ctrl+C to interrupt frozen boot code.
Helps prevent the filesystem from getting formatted by mistake, among other
things.  For example, on a Pico board, entering Ctrl+D and Ctrl+C fast many
times will eventually wipe the filesystem (without warning or notice).

Further rationale: Ctrl+C is used a lot by automation scripts (eg mpremote)
and UI's (eg Mu, Thonny) to get the board into a known state.  If the board
is not responding for a short time then it's not possible to know if it's
just a slow start up (eg in _boot.py), or an infinite loop in the main
application.  The former should not be interrupted, but the latter should.
The only way to distinguish these two cases would be to wait "long enough",
and if there's nothing on the serial after "long enough" then assume it's
running the application and Ctrl+C should break out of it.  But defining
"long enough" is impossible for all the different boards and their possible
behaviour.  The solution in this commit is to make it so that frozen
start-up code cannot be interrupted by Ctrl+C.  That code then effectively
acts like normal C start-up code, which also cannot be interrupted.

Note: on the stm32 port this was never seen as an issue because all
start-up code is in C.  But now other ports start to put more things in
_boot.py and so this problem crops up.

Damien George 38e7b842c6 ports: Implement simple write polling for stdout.
This is a best-effort implementation of write polling.  It's difficult to
do correctly because if there are multiple output streams (eg UART and USB
CDC) then some may not be writeable while others are.  A full solution
should also have a return value from mp_hal_stdout_tx_strn(), returning the
number of bytes written to the stream(s).  That's also hard to define.

The renesas-ra and stm32 ports already implement a similar best-effort
mechanism for write polling.

cpottle9 c80e7c14e6 rp2: Allocate GC heap from unused RAM.
Borrowing an idea from the mimxrt port (also stm32 port): in the loader
input file memmap_mp.ld calculate __GcHeapStart and __GcHeapEnd as the
unused RAM.  Then in main.c use these addresses as arguments to gc_init().

The benefits of this change are:

1) When libraries are added or removed in the future changing BSS usage,
   main.c's sizing of the GC heap does not need to be changed.

2) Currently these changes make the GC area about 30 KBytes larger, eg on
   PICO_W the GC heap increases from 166016 to 192448 bytes.  Without that
   change this RAM would never get used.

3) If someone wants to disable one or more SRAM blocks on the RP2040 to
   reduce power consumption it will be easy: just change the MEMORY section
   in memmap_mp.ld.  For instance to not use SRAM2 and SRAM3 change it to:

        MEMORY
        {
            FLASH(rx) : ORIGIN = 0x10000000, LENGTH = 2048k
            RAM(rwx) : ORIGIN =  0x21000000, LENGTH = 128k
            SCRATCH_X(rwx) : ORIGIN = 0x20040000, LENGTH = 4k
            SCRATCH_Y(rwx) : ORIGIN = 0x20041000, LENGTH = 4k
        }

   Then to turn off clocks for SRAM2 and SRAM3 from MicroPython, set the
   appropriate bits in WAKE_EN0 and SLEEP_EN0.

Tested by running the firmware.uf2 file on PICO_W and displaying
micropython.mem_info().  Confirmed GC total size approximately matched the
size calculated by the loader.
