Subject: [patch] Partial support for mtd on collie
Date: Tue, 15 Nov 2005 00:07:39 +0100 [thread overview]
Message-ID: <20051114230739.GA17587@elf.ucw.cz> (raw)
This adds support for sharp collie. I probably got regions wrong,
because chip can not be written to, but readonly support is still
better than no support at all.
