Can you instead use the DEBUG_UART feature? It should already be
supported for Rockchip if you enable that option and provide the
settings,
but it should support fdt I want to use DEBUG_UART feature, but i
disable it in SPL since
rk3036 sram size, so i implentment a uart driver, so we can use
debug uart in SPL.

Simon
