Add initial support for Compulab CM-FX6 CoM. Support includes MMC, SPI flash, and SPL with dynamic DRAM detection.
Cc: Igor Grinberg grinberg@compulab.co.il Cc: Stefano Babic sbabic@denx.de Cc: Tom Rini trini@ti.com Cc: Marek Vasut marex@denx.de Cc: Simon Glass sjg@chromium.org Acked-by: Marek Vasut marex@denx.de Signed-off-by: Nikita Kiryanov nikita@compulab.co.il --- Changes in V4: - Adapt to use Kconfig - Refactor code to work without ulong bank(1|2)_size variables - Remove get_board_rev(); reintroduce in a later patch - Move usdhc structs to cm_fx6.c - Initialize all ddr related structs statically - Use get_cpu_type() and spl_boot_device() - Kill #define CONFIG_SYS_L2CACHE_OFF - Use load instead of fatload in environment scripts - Remove nand related environment variables; reintroduce in a later patch - Move usdhc3 clock initialization to another patch.
Changes in V3: - Remove CONFIG_SYS_TEXT_BASE from config file to not clash with the one supplied by imx6_spl.h
Changes in V2: - Remove unnecessary line removal from arch/arm/cpu/armv7/mx6/ddr.c - Move probe_mmdc_config() code straight to dram_init() - Use imx6_spl.h - Use imx_ddr_size() NOTE: the correctness of this patch now depends on https://patchwork.ozlabs.org/patch/376095/
