Philipp Tomsich	3b4f87735d	rockchip: bootrom: add definitions to retrieve BROM boot-source ... The Rockchip BROM allows reading where it booted from from SRAM. This adds the necessary definitions (as received from Kever) for the location of this information in the RK3399's SRAM and naming for the constants used.

Simon Glass	e1bc64eec2	rockchip: Print a message when returning to the bootrom ... At present if the return to bootrom fails (e.g. because you are not using the Rockchip's bootrom's pointer table in MMC) then the board prints SPL message and hangs. Print a message first if we can, to help in understanding what happened when it hangs.

Heiko Stübner	aade077e43	rockchip: Move bootrom-related declarations to a header ... So far spl-boards have declared the back_to_brom() function as simple extern in the files themself. That doesn't scale well if every boards defines this on its own. Therefore move the declarations to a bootrom header.
