Subject: [PATCH] fix(rcar3-drivers): check for length underflow
Origin: https://github.com/ARM-software/arm-trusted-firmware/commit/9778b270e29bac3e16f57f9557098c45858c05de
https://github.com/renesas-rcar/arm-trusted-firmware/commit/b596f580637bae919b0ac3a5471422a1f756db3b
Make sure the length of the payload is not longer than the
DRAM size in check_load_area(), and make sure the payload
end does not cross protected area start.
