- 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. Signed-off-by: Philipp Ebensberger
