+	help

+config ROCKCHIP_MAX_SPL_SIZE
+	hex "Max size of rockchip's spl loader"
+	help
+	  Different chip may have different sram size. And if we want to jump
+	  back to the bootrom after spl, we may need to reserve some sram space
+	  for the bootrom.
+	  The max spl loader size should be sram size minus reserved
+	  size(if needed)
