we can use this config to disable rockchip serial driver in SPL stage, since some rockchip soc sram size is small(rk3036 etc), so we don't want rockchip serial driver build in SPL, but we still want use common debug driver in SPL.

Also you should add this new CONFIG to drivers/serial/Kconfig, below the existing (non-SPL) one.

You should add this to the rk3288 defconfig files, instead of here. Kconfig items should not be added to config header files - in fact we plan to eventually remove the config header files.
#define CONFIG_SYS_NS16550 #define CONFIG_SYS_NS16550_MEM32
#define CONFIG_SPL_BOARD_INIT

Actually, serial_rockchip.c has been removed in mainline. So you may not need this patch, or maybe it can be reduced in size. Please check the current u-boot-rockchip/master.
i cherry-pick the
[PATCH 2/2] rockchip: rk3036: enable CONFIG_DEBUG_UART, and use ns16550 uart driver
in u-boot-rockchip/master branch, build it, but fail, it is will call hang() in arch/arm/lib/div0, so i need to define CONFIG_SPL_LIBGENERIC_SUPPORT, but if i do it, the spl size too big.
