Subject: [PATCH v5 06/22] sh: FDT address save before bank change
Date: Sun, 03 Jul 2016 16:46:26 +0000 [thread overview]
Message-ID: <1467564402-2649-7-git-send-email-ysato@users.sourceforge.jp> (raw)
In-Reply-To: <1467564402-2649-1-git-send-email-ysato@users.sourceforge.jp>
SH3/4 have register bank of R0-R7.
Preset FDT address assigned bank depend on boot loader.
Before setting a bank because we don't depend on a boot loader, it's evacuated.
