[PATCH v2 0/3] mkimage/rockchip: support packing optional second level boot-loader

[Jeffy Chen]

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 v2:
Do rc4 encode for boot data when needed as well.
