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
