Signed-off-by: Otavio Salvador otavio@ossystems.com.br --- Changes in v6: - Remove 'saveenv' command as it is not need - Move environment settings to environment section - Use 1s boot delay
Changes in v5: - Use 4bit bus for mmc
Changes in v4: - Fix build warnings
Changes in v3: - Removed unused macro for GPMI setting in spl_boot.c
Changes in v2: - Add DUART in commitlog - Remove AUART MUX setup as it is unused - Remove wrong comment in mx23evk.h board config - Use single line comments in mx23evk.h board config - Use '=>' as prompt - Remove SPI, RTC and USB support as those where not tested yet
