Philipp Ebensberger	87f97e490c	mimxrt/sdcard: Implement SDCard driver. - Configures `PLL2->PFD0` with 198MHz as base clock of `USDHCx` peripheral. - Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD` - Adds creation of pin defines for SDCard to make-pins.py - Adds new configuration option for SDCard peripheral pinout to mpconfigport.h - Adds interrupt handling support instead of polling - Adds support for `ADMA2` powered data transfer - Configures SDCard to run in HS (high-speed mode) with 50MHz only! SDCard support is optional and requires `USDHC` peripheral. Thus this driver is not available on `MIMXRT1010_EVK`. SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1` in mpconfigboard.mk. Signed-off-by: Philipp Ebensberger	2021-09-07 20:45:33 +02:00

This commit includes: - add support for Hyperflash - modify MIMXRT1060_EVK and MIMXRT1064_EVK to change from QSPI to hyperflash. - minor incidental changes to other boards so they still build Note: Erasing a sector on the hyperflash is slow.

mimxrt/sdcard: Implement SDCard driver.

- Configures `PLL2->PFD0` with **198MHz** as base clock of
	`USDHCx` peripheral.
- Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD`
- Adds creation of pin defines for SDCard to make-pins.py
- Adds new configuration option for SDCard peripheral pinout
        to mpconfigport.h
- Adds interrupt handling support instead of polling
- Adds support for `ADMA2` powered data transfer
- Configures SDCard to run in HS (high-speed mode) with **50MHz** only!

SDCard support is optional and requires `USDHC` peripheral.
Thus this driver is not available on `MIMXRT1010_EVK`.
SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1`
in mpconfigboard.mk.

mimxrt: Add support for Hyperflash chips.

Hyperflash is used by the MIMXRT1050_EVKB, MIMXRT1060_EVK and
MIMXRT1064_EVK boards.

This commit includes:
- add support for Hyperflash
- modify MIMXRT1060_EVK and MIMXRT1064_EVK to change from QSPI to
  hyperflash.
- minor incidental changes to other boards so they still build

Note: Erasing a sector on the hyperflash is slow. It takes about a second,
which seems too long, but matches the data sheet.

mimxrt/boards: Add board configuration files for Teensy 4.1.

These are at the moment more or less identical to the Teensy 4.0 files,
except for the pins.csv file and the flash size.
