Jonas Karlman 4773e9d5ed rockchip: Use an external TPL binary on RK3568 ... Rockchip SoCs typically use U-Boot TPL to initialize DRAM, then jumps back to BootRom to load next stage, U-Boot SPL, into DRAM. BootRom then jumps to U-Boot SPL to continue the normal boot flow. However, there is no support to initialize DRAM on RK35xx SoCs using U-Boot TPL and instead an external TPL binary must be used to generate a bootable u-boot-rockchip.bin image. Add CONFIG_ROCKCHIP_EXTERNAL_TPL to indicate that an external TPL should be used. Build U-Boot with ROCKCHIP_TPL=/path/to/ddr.bin to generate a bootable u-boot-rockchip.bin image for RK3568.
