This replaces the previous make-pin-table.py with an implementation based
on boardgen.py.
- MICROPY_PY_MACHINE_PIN_BOARD_CPU macro is removed. This isn't optional
on other ports, so no need for it to be optional on SAMD.
- pin_af_table is removed, and lookups just search the cpu dict instead
(this saves N*wordsize bytes of firmware size to have this extra table).
- pins.csv is now BOARD,CPU to match other ports.

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
that reduced set.
- 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.
Work done in conjunction with Matt Trentini <matt.trentini@gmail.com>.

SAMD21: set the filesystem type to LFS1.
SAMD51: the type is already set to LFS2, support is now dropped for LFS1.
It has not been used and dropping it saves 10 k of flash.

The QSPI driver provides the interface for using an on-board QSPI flash for
the filesystem. It provides the same methods as the driver for the
internal flash and uses the same name. Therefore, only one of the drivers
for internal flash, SPI flash and QSPI flash must be enabled at a time.

The SPI flash driver includes the block device for being used as a
filesystem. It provides the same methods as the driver for the internal
flash.

For SAMD21 devices, the board flash signals must be named in pins.csv as
FLASH_MOSI, FLASH_MISO, FLASH_SCK, FLASH_CS for creating the SPI object.
And rename the QSPI pins to QSPI_xxxx instead of FLASH_xxx.

Such that they are easier to adapt. The maximum code size is set by:
MICROPY_HW_CODESIZE=xxxK
in mpconfigmcu.mk for the MCU family as default or in mpconfigboard.mk for
a specific board. Setting the maximum code size allows the loader to error
out if the code gets larger than the space dedicated for it.

Remove two SPARKFUN_SAMD51_THINGS_PLUS pin definitions. There were
definitions of TXD and RXD, but these pins do not exist on the board. They
were only shown in the schematics.
Also remove any reference to LED_. This is just a text change, no
functional change.
For compatibility with other ports. Code increase up to ~1250 bytes for
SAMD21. The feature is configurable via MICROPY_PY_MACHINE_PIN_BOARD_CPU
in case flash memory is tight.
ADC: The argument of vref=num is an integer. Values for num are:
SAMD21:
0 INT1V 1.0V voltage reference
1 INTVCC0 1/1.48 Analog voltage supply
2 INTVCC1 1/2 Analog voltage supply (only for VDDANA > 2.0V)
3 VREFA External reference
4 VREFB External reference
SAMD51:
0 INTREF internal bandgap reference
1 INTVCC1 Analog voltage supply
2 INTVCC0 1/2 Analog voltage supply (only for VDDANA > 2.0v)
3 AREFA External reference A
4 AREFB External reference B
5 AREFC External reference C (ADC1 only)
DAC: The argument of vref=num is an integer. Suitable values:
SAMD21:
0 INT1V Internal voltage reference
1 VDDANA Analog voltage supply
2 VREFA External reference
SAMD51:
0 INTREF Internal bandgap reference
1 VDDANA Analog voltage supply
2 VREFAU Unbuffered external voltage reference (not buffered in DAC)
4 VREFAB Buffered external voltage reference (buffered in DAC).
Changes are:
- Remove the LED_Pxxx definitions from pins.csv, now that the LED class is
gone.
- Remove the '-' lines.
- Add default lines for USB and SWCLK, SWDIO.
Pin numbers are now the MCU port numbers in the range:
PA0..PA31: 0..31
PB0..PB31: 32..63
PC0..PC31: 64..95
PD0..PD31: 96..127
Pins can be denoted by the GPIO port number, the name as defined in
pins.csv or a string in the form Pxnn, like "PA16" or "PD03".
The pins.c and pins.h files are now obsolete. The pin objects are part of
the AF table.
As result of a simplification, the code now supports using pin names or
numbers instead of pin objects for modules like UART, SPI, PWM, I2C, ADC,
pininfo.
Instead of being hard-coded, and then it works for all MCUs.
That fits except for a Sparkfun SAMD51 Thing Plus (known) bug, which uses
192k - 4 as magic address. Therefore, that address is set as well to avoid
a problem when this bug is fixed by Sparkfun.
It now prints lines like:
Pin("D9", mode=IN, pull=PULL_UP, GPIO=PA07)
or
LED("LED")
showing for consistency the names as given in pins.csv. For pins, the GPIO
numer is printed as well for a reference.
Changes are:
- The pin-af-table-SAMDxx.csv file are moved to the mcu directories with
the name as pin-af-table.csv.
- The handling in Makefile and pin_af.c is simplified.
Two new compile flags are:
MICROPY_HW_DFLL_USB_SYNC: Effective only if DFLL48 does not run from the
crystal. It will synchronize the DFLL48M clock with the USB's SOF pulse.
If no USB is connected, it will fall back to open loop mode. The DFLL48M
clock is then pretty precise, but with a higher clock jitter at SAMD51
devices.
MICROPY_HW_MCU_OSC32KULP: Effective only if the devics uses a crystal as
clock source. Run the MCU clock from the ULP 32kHz oszillator instead of
the crystal. This flag was added to cater for a interference problem of
the crystal and Neopixel/Debug pins at Adafruit FEATHER Mx boards, which
causes the board to crash. Drawback: ticks_ms() and time.time() vs. than
ticks_us() and the peripherals like PWM run at not synchronous clocks.
Fixes are:
- Pin definitions for ADAFRUIT_FEATHER_Mx_EXPRESS and
ADAFRUIT_ITSYBITSY_M4_EXPRESS.
- For ADAFRUIT_ITSYBITSY_M0_EXPRESS, change the MISO/MOSI name.
- For MINISAM_M4, add the default SPI pins.
- For boards with 32k crystal, add the XOSC32K setting.
These two boards are used for testing, so it is favorable to have them
added early.
The full test set is:
- ADAFRUIT_FEATHER_M4_EXPRESS: SAMD51 with 32kHz crystal.
- ADAFRUIT_ITSYBITSY_M0_EXPRESS: SAMD21 without crystal.
- ADAFRUIT_ITSYBITSY_M4_EXPRESS: SAMD51 without crystal.
- SEEED_XIAO: SAM21 with 32kHz crystal.
These files that are reformatted only now fall under the list of files to
apply uncrustify/black formatting to.
