[U-Boot-Users] [PATCH RFC 0/5] i.MX31: Add NAND support and new PDK board.

[Magnus Lilja]

Hi all

This series of patches adds support for the NAND flash controller in the
i.MX31 device and also introduces the Freescale i.MX31 PDK board.

The patches are based on Scott Wood's testing branch of the NAND git tree.

At the moment, the patch series does not add support for booting from
NAND. This means that the PDK board support assumes that some other entity
configures the SDRAM and loads U-boot into RAM (e.g. another bootloader or a
JTAG debugger). Support for NAND boot is in progress and will be submitted
later.

The NAND driver is based on Freescale's Linux driver from their BSP. I've
cleaned it up a bit and made the (minor) modifications necessary for
U-boot. Perhaps the driver should be cleaned up even more, there are some
CONFIG_MTD_MXC_* leftovers in the driver.

I have tested the driver on the Litekit (small page NAND) and on the PDK
(large page NAND) by having the U-boot environment placed in NAND.


Comments are welcome!
