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'

Changes requested are still pending from v1.
When starting to merge this, I encountered the same warnings and the nested
#if/#elif statements as last time...
None of the changes I had requested against v1 have been done.
Please refer to
https://patchwork.ozlabs.org/patch/836639/
Please revise, so we can get this merged next week as we should get this fix
in as quickly as possible...
Thanks.
Philipp.
