Subject: Re: [PATCH v4 04/11] mtd: Add MPC5121 NAND Flash Controller driver
Date: Tue, 23 Feb 2010 15:54:04 +0000	[thread overview]
Message-ID: <4B83FA1C.8000902@marel.com> (raw)
In-Reply-To: <1266307868.11659.177.camel@localhost>

Any special reason this in MPC5121 Revision 2 only?
I did not see anything that contradicted the rev 3 manual in the code.

But there is one harmless bug (since the NFC_CMD_FAIL symbol is never used), i.e.

  /* Bit Definitions: NFC_WRPROT */

The NAND chip is is detected (given that I disable the Revison check),
but the /dev7mtd0 is not accessable as block device. Is that normal?
The UBIFS also gives up I am assuming because the /dev/mtd0 is not block device.
