Subject: [PATCH v4 06/22] sh: FDT address save before bank change
Date: Wed, 29 Jun 2016 22:40:51 +0900 [thread overview]
Message-ID: <1467207667-15768-7-git-send-email-ysato@users.sourceforge.jp> (raw)
In-Reply-To: <1467207667-15768-1-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.
Changes v4
none
