ed5e3598f1 mimxrt/Makefile: Fix internal flash configuration and build. 2023-04-11 17:03:28 +10:00

5e990cc27f mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board.
The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.

The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
  being the 1GB interface.

The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.

This work was done in collaboration with @alphaFred.

84b76e4fbf mimxrt: Allow for board-specific flash driver files.
If in a board's mkconfigboard.mk the following symbol is set:

MICROPY_HW_BOARD_FLASH_FILES = 1

then the files:

($BOARD)_flexspi_flash_config.h  and
qspi_nor_flash_config.c  and/or
qspi_hyper_flash_config.c

are expected in the board directory. Otherwise the common files from
the hal directory are used.

5ca56aaf16 mimxrt: Tidy up the board flash related files.
- Move the qspi_xxxx_flash_config.c files to hal.
  It turned out that they are less board than flash type specific.
- Change to a common flexspi_flash_config.h header file.

0d7366c912 mimxrt: Rework flash configuration.
- Moves definition of BOARD_FLASH_SIZE and other header files related to
	flash configuration into the Makefile.
- Adds board specific clock_config.h.
- Adds board.h, pin_mux.h, and peripherals.h as they are
	required by NXP MCU SDK in order to use our own clock_config.h.
- Renames board specific FlexSPI configuration files.
- Updates flash frequency of MIMXRT1020_EVK
- Creates separated flash_config files for QSPI NOR and
	QSPI Hyper flash.
- Unifies VFS start address to be @ 1M for 1010 and 1020 boards.
- Unifies 1050EVK boards
- Adds support to both NOR and HyperFlash on boards with
	both capabilities.
- Adds automatic FlexRAM initialization to start-up code based on
	linker script and NXP HAL.
- Applies code formatting to all files in mimxrt port.

With this change the flash configuration is restructured and
organized. This simplifies the configuration process and
provides a better overview of each board's settings. With the integration
of clock_config.h, board.h, pin_mux.h, and peripherals.h we gain better
control of the settings and clock configurations. Furthermore the
implementation of an explicit FlexRAM setup improves the system
performance and allows for performance tuning.

1074c784b0 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.
