Testing has shown that writing to eMMC using DDR52 mode does not seem to work on RK356x and RK3588 boards. A simple test of writing a single block to e.g. sector 0x4000 fails: # Rescan using DDR52 mode => mmc rescan 4 # Write a single block to sector 0x4000 fails with ERROR => mmc write 20000000 4000 1 With the MMC_SPEED_MODE_SET Kconfig option enabled. Fix this by removing the mmc-ddr-1_8v prop from sdhci nodes in affected board u-boot.dtsi files. Signed-off-by: Jonas Karlman <jonas@kwiboo.se> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
