Using DMA to load TF-A into SRAM fails when booting from eMMC on RK3588.
## Checking hash(es) for Image atf-3 ... sha256 error! Bad hash value for 'hash' hash node in 'atf-3' image node spl_load_simple_fit: can't load image loadables index 2 (ret = -1) mmc_load_image_raw_sector: mmc block read error
Fix this by using PIO mode in SPL and limit the number of blocks used in a single read command to avoid triggering Data End Bit Error interrupt.
