Help text

This option enables the support for loading compressed firmware files. The caller of firmware API receives the decompressed file content. The compressed file is loaded as a fallback, only after loading the raw file failed at first.

Currently only XZ-compressed files are supported, and they have to be compressed with either none or crc32 integrity check type (pass "-C crc32" option to xz command).

Compressed firmware support does not apply to firmware images that are built into the kernel image (EXTRA_FIRMWARE).
