AST2600 leverages the FIT hash/signature verification to fulfill secure boot trust chain. To improve the performance and save SW code size for those crypto operations, the two HW crypto engine, HACE and ACRY, are enabled. However, both of the engines can only access to data stored in DRAM space. Therefore, we need to move the FIT image into DRAM before the booting. This patch update the CONFIG_BOOTCOMMAND to execute the pre-defined ENV variable which consists of FIT image copy to memory and booting. Signed-off-by: Chia-Wei Wang <chiawei_wang@aspeedtech.com>
