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.

Fixes issue #11026.

b7ea90d4cb rp2/machine_uart: Fix setting of UART LCR parameters.
Prior to this change, setting of UART parameters like parity, stop bits or
data bits did not work correctly.  As suggested by @iabdalkader, adding
__DSB() fixes the problem, making sure that changes to the UART LCR_H
register are seen by the peripheral.

Note: the FIFO is already enabled in the call to uart_init(), so the call
to uart_set_fifo_enabled() is not required, but kept for visibility.

Fixes issue #10976.

711bac511e rp2/main: Keep UART REPL with DEBUG=1 and MICROPY_HW_ENABLE_UART_REPL=1.
For builds with DEBUG=1 and MICROPY_HW_ENABLE_UART_REPL=1, calling
stdio_init_all() in main() detaches the UART input from REPL.  This change
suppresses calling stdio_init_all() then.

be686e634e rp2: Allow disabling USB via MICROPY_HW_ENABLE_USBDEV config.
Previously, setting MICROPY_HW_ENABLE_USBDEV to 0 caused build errors.  The
change affects the nrf and samd ports as well, so MICROPY_HW_ENABLE_USBDEV
had to be explicitly enabled there.

The configuration options MICROPY_HW_ENABLE_USBDEV and
MICROPY_HW_ENABLE_UART_REPL are independent, and can be enabled or disabled
by a board.

7ea192af05 nrf/modules/machine/uart: Add timeout keyword options and "any" method.
Changes in this commit:
- Add the timeout and timeout_char keyword options.
- Make uart.read() non-blocking.
- Add uart.any().
- Add ioctl MP_STREAM_POLL handling.
- Change uart.write() into non-busy waiting. uart.write() still waits until
  all data has been sent, but calls MICROPY_EVENT_POLL_HOOK while waiting.
  uart.write() uses DMA for transfer.  One option would be to add a small
  local buffer, such that transfers up to the size of the buffer could be
  done without waiting.
- As a side effect to the change of uart.write(), uart.txdone() and ioctl
  flush now report/wait correctly for the end of transmission.
- Change machine_hard_uart_buf_t in machine_hard_uart_obj_t to an instance
  of that struct, rather than a pointer to one.

05bb26010e samd: Always provide the machine.RTC class.
Even if boards do not have a clock crystal.  In that case, the clock
quality will be very poor.

Always having machine.RTC means that the date/time can be set in a way that
is consistent with other ports.

This commit also removes the special code in modutime.c for devices without
the RTC class.

Using extmod/machine_pwm.c for the Python bindings and the existing

Properties:
- Frequency range 1-3906 Hz.
- All PWM outputs run at the same frequency but can have different duty
  cycles.
- Limited to the P0.x pins.

Since it uses the existing softpwm.c mechanism, it will be affected by
playing music with the music class.

This is a breaking change, making the hardware PWM on the nrf port
compatible with the other ports providing machine.PWM.

Frequency range 4Hz - ~5.4 MHz.  The base clock range is 125kHz to 16 MHz,
and the divider range is 3 - 32767.

The hardware supports up to four outputs per PWM device with different duty
cycles, but only one output is (and was) supported.

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.
