From: Peng Fan <[email protected]> Add support for booting compressed kernel Image.gz by defining kernel_comp_addr_r and kernel_comp_size in the default environment.
Set kernel_comp_addr_r to a high memory region to provide a dedicated decompression buffer, avoiding overlap between compressed input and decompressed output. Also adjust CONFIG_SYS_LOAD_ADDR from 0x40480000 to 0x40400000. With TEXT_OFFSET=0, the kernel is relocated directly to loadaddr, so separating decompression and execution regions is required to guarantee safe decompression without additional copying.
