Subject: [PATCH] fix devicetree alignment
Date: Thu,  1 Nov 2012 12:49:31 +0100	[thread overview]
Message-ID: <1351770573-30009-1-git-send-email-s.hauer@pengutronix.de> (raw)

The following fixes a nasty problem with passing devicetrees to
the (ARM-) Kernel. In short, we are not allowed to cross 1MiB
boundaries with the devicetree. This can happen sometimes since
we allocate space for the devicetree using memalign(). I think
this is rather a kernel bug since this restriction is not documented
anywhere. Anyway, working around it in barebox is easy enough.
