Subject: Re: [patch 3/4 2.6.23-rc2 + mm2-git-mmc] MMC core learns about SPI
Date: Wed, 29 Aug 2007 11:22:47 +0200 [thread overview]
Message-ID: <20070829092247.GA15021@pengutronix.de> (raw)
In-Reply-To: <200708080911.33099.david-b-yBeKhBN/0LDR7s880joybQ@public.gmane.org>
Hi David and all,
I need the following patch on my (little endian) System to successfully
read the csd/cid structure.
Sascha
CSD/CID is transfered in big endian format. Convert it to cpu endianess.
