This patch adds NAND Flash Controller driver for MPC5121 revision 2. All device features, except hardware ECC and power management, are supported.
This NFC driver replaces the one orignally posted by John Rigby:
"[PATCH] Freescale NFC NAND driver"
It's a port of the Linux driver version posted by Piotr Ziecik a few weeks ago. Using this driver has the following advantages (from my poont of view):
- Compatibility with the Linux NAND driver (e.g. ECC usage)
I do not see ADS5121 support in posted driver code. ADS5121 board controls NAND chip selects via external CPLD and do not use controller chip select signals. Linux driver has workaround for this special case.
Yes, I know. I explicitly removed this code because of two reasons:
a) My basic testing platform was the esd mecp5123 board.
b) I did some quick tests on the MCP5121ADS with this code (without this ADS specific chip-select handling) and didn't see any error.
So I suggest to add the code as is for now. Such board specific routines can be added later on when really needed.
