When enabling back-to-bootrom, the bootrom would continue to load the second level boot-loader. And currently we are packing it by appending the generated image manually (with a predefined max size):
./firefly-rk3288/tools/mkimage -n rk3288 -T rksd -d \ firefly-rk3288/spl/u-boot-spl-dtb.bin out && \ cat firefly-rk3288/u-boot-dtb.bin >> out
This series add support of packing optional second level loader with mkimage tool: ./tools/mkimage -n rk3399 -T rksd -d \ rk3399_ddr_800MHz_v1.24.bin:rk3399_miniloader_v1.19.bin out
Changes in v3: Rule out hdr when checking spl size. (The bootrom would put hdr on stack.)
Changes in v2: Do rc4 encode for boot data when needed as well.
