* mxc_nand: fix a problem writing more than 32MBHelmut Raiger2011-10-031-1/+12
| | | | | | | | | | | | | | When writing 0x4000 to the unlockend_blkaddr register, large writes to a 2k page NAND sometimes fail. The current kernel driver writes 0xFFFF to this register for V2 of the nand controller. However on an i.MX31 this also fixes writes larger than 32MB. The datasheet is very unspecific, but (0x4000=16384)*2000 roughly fits the limits we're encountering with NAND writes. This problem might be NAND chip specific.

* MXC: Add large page oob layout for i.MX31 NAND controller.Magnus Lilja2010-01-191-0/+12
| | | | | | | | | | | | | Import the large page oob layout from Linux mxc_nand.c driver. The CONFIG_SYS_NAND_LARGEPAGE option is used to activate the large page oob layout. Run time detection is not supported as this moment. This has been tested on the i.MX31 PDK board with a large page NAND device. Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>
