Decompression is handled transparently within cbfs_get_file_content: const char *name = "foo.bmp"; void *dst = cbfs_get_file_content(media, name, type, NULL); To keep things consistent, a couple of API changes were necessary: - cbfs_get_file_content always returns a copy of the data, even for uncompressed files. It's the callers responsibility to free the memory. - same for cbfs_load_payload and cbfs_find_file. - cbfs_load_optionrom doesn't take a "dest" argument anymore but always returns a copy of the data, for compressed and uncompressed files. Like with cbfs_get_file_content, the caller is responsible to free it. It also decompresses based on extended file attributes instead of the cbfs_optionrom subheader that libpayload specified but that (AFAIK) nobody ever used, given that there's not even tooling for that.
