Subject: [PATCH v2 06/17] sh: FDT address save before bank change
Date: Sun, 12 Jun 2016 06:54:24 +0000 [thread overview]
Message-ID: <1465714475-24111-7-git-send-email-ysato@users.sourceforge.jp> (raw)
In-Reply-To: <1465714475-24111-1-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.
