- Add SD secure boot target for ls1043ardb.
- Implement board specific spl_board_init() to setup CAAM stream ID and
corresponding stream ID in SMMU.
- Change the u-boot size defined by a macro for copying the main U-Boot by SPL
to also include the u-boot Secure Boot header size as header is appended to
u-boot image. So header will also be copied from SD to DDR.
- CONFIG_MAX_SPL_SIZE is limited to 90K.SPL is copied to OCRAM (128K) where 32K
are reserved for use by boot ROM and 6K for secure boto header
- Error messages during SPL boot are limited to error code numbers instead of strings
to reduce the size of SPL image
