Atish Patra 414c34ed55 image: Add compressed Image parsing support in booti. ... Add compressed Image parsing support so that booti can parse both flat and compressed Image to boot Linux. Currently, it is difficult to calculate a safe address for every board where the compressed image can be decompressed. It is also not possible to figure out the size of the compressed file as well. Thus, user need to set two additional environment variables kernel_comp_addr_r and filesize to make this work. Following compression methods are supported for now. lzma, lzo, bzip2, gzip. lz4 support is not added as ARM64 kernel generates a lz4 compressed image with legacy header which U-Boot doesn't know how to parse and decompress. Tested on HiFive Unleashed and Qemu for RISC-V. Tested on Qemu for ARM64.
