Rockchip SoCs only need boot0 hook at SPL, and the U-Boot proper do not need it.
The very beginning of U-Boot proper is different between armv7 and armv8: armv7 start with ARM_VECTORS while armv8 start with 'b reset'.
Here is the map of very beginning for all cases: armv7 SPL: TAG(overwrite 'b 1f')+'b reset' + ARM_VECTORS armv7 U-Boot: ARM_VECTORS armv8 SPL: TAG(overwrite 'b 1f')+'b reset' + Reserved_iram(rk3399) armv8 U-Boot: 'b reset'
