Subject: [PATCH] ARM: restart: move SWRST based S3C platforms to machine_desc hook
Date: Mon, 19 Dec 2011 13:25:55 +0100 [thread overview]
Message-ID: <201112191325.56090.heiko@sntech.de> (raw)
In-Reply-To: <03dd01ccbe48$88ed7d50$9ac877f0$%kim@samsung.com>
S3C2412/S3C2416/S3C2443 use a special register to signal the reset to
the processor and used therefore the s3c24xx_reset_hook mechanism in the
s3c24xx-specific arch reset.
This patch introduces restart functions for these architectures,
moves the board files to them and removes the s3c24xx_reset_hook
infrastructure, as all users are gone.
Signed-off-by: Heiko Stuebner <heiko@sntech.de>

@Kgene: This is my first cleanup step, done before your s3c64xx mail arrived,
which transforms the 2412,2416 and 2443 arches which use the special SWRST
register to do the reset. Just if it helps :-)
