rockchip: mkimage: support packing optional second level boot-loader
Support packing optional second level boot-loader: $ ./tools/mkimage -n rk3399 -T rksd -d \ rk3399_ddr_800MHz_v1.24.bin:rk3399_miniloader_v1.19.bin out -v Adding Image rk3399_ddr_800MHz_v1.24.bin Size 116492(pad to 116736) Adding Image rk3399_miniloader_v1.19.bin Size 88060(pad to 88064) Image Type: Rockchip RK33 (SD/MMC) boot image Init Data Size: 116736 bytes Boot Data Size: 88064 bytes Mainly parse init file and boot file from datafile option, copy them to the image with 2KB alignment.
