Testing has shown that writing to eMMC using a slower mode then HS200 typically generate an ERROR on first attempt on RK3588.
# Rescan using MMC legacy mode => mmc rescan 0 # Write a single block to sector 0x4000 fails with ERROR => mmc write 20000000 4000 1 # Write a single block to sector 0x4000 now works => mmc write 20000000 4000 1 With the MMC_SPEED_MODE_SET Kconfig option enabled. Writing to eMMC using HS200 mode work more reliably than slower modes on RK35xx boards. Enable MMC_HS200_SUPPORT Kconfig option by default to prefer use of HS200 mode on RK356x and RK3588.
