[PATCH 0/9] Firmware: support compressing firmware files

[Sascha Hauer]

TF-A and OP-TEE can reach significant sizes nowadays and are currently
uncompressed in the PBL. This series supports including them in compressed
form in the PBL. To accomplish this we introduce a new macro
get_builtin_firmware_compressed() which returns the compressed firmware
image. This can be decompressed afterwards with fwobj_uncompress().
There are always both the compressed and uncompressed images generated,
so the code can decide which one to use. This series switches over the
Rockchip TF-A and OP-TEE binaries to use the compressed variants.

Also included in this series are some unrelated patches I stumbled upon
while creating this series.
