Changes in v6: - Convert SZ_XXX into hex in ap121.h - Remove useless CONFIG_SYS_INIT_SP_OFFSET in ap121.h - Add board_early_init_f for DDR and pin initialization - Select UART and SPI in ap121_defconfig
Changes in v5: - Move CONFIG_SYS_TEXT_BASE into ap121.h, and remove config.mk - Remove useless README file - Remove useless checkboard function
Changes in v4: None Changes in v3: - Add support for device tree
Changes in v2: - Add a reference board implemention
