From: Jeffy Chen <jeffy.chen at rock-chips.com>
Our chips may have different max spl size and spl header, so
we need to add configs for that.

+ Rockchip's bootrom requires the spl loader to start with a 4-bytes

+ 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)
