Subject: [PATCH] ppc64/kexec/purgatory Fix RTAS calls in Little Endian mode.
Date: Mon, 13 Jan 2014 18:55:36 +0100 [thread overview]
Message-ID: <20140113175536.14913.16060.stgit@nimbus> (raw)
RTAS is expecting parameters in Big Endian order so we have to byte swap
them in LE mode.
In the purgatory RTAS calls are only made for debug output.
