arm: ls1043ardb: Add SD secure boot target
- Add SD secure boot target for ls1043ardb.
- Implement FSL_LSCH2 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 90KB. 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.
