Here the description from Brian Brelsford <Brian_Brelsford@dell.com>:
The Hynix part returns a 0x1d in the 4th ID byte. The Samsung part
returns a 0x15. In the code fragment below bits [1:0] determine the
page size, it is ANDed via "(extid & 0x3)" then shifted out. The
next field is also ANDed with 0x3. However this is a one bit field
as defined in the Hynix and Samsung parts in the 4th ID byte that
determins the oobsize, not a two bit field. It works on Samsung as
bits[3:2] are 01. However for the Hynix there is a 11 in these two
bits, so the oob size gets messed up.
I checked the correct linux code and the suggested fix from Brian is
also available in the linux nand mtd driver.

This code will optimize the DDR2 controller setup on a board specific
basis.
Note: This code doesn't work right now on the NAND booting image for the
Sequoia board, since it doesn't fit into the 4kBytes for the SPL image.

- fix a typo in V38B config file
- move watchdog initialisation earlier in the boot process
- add "wdt=off" to default kernel command line (disables kernel watchdog)
The soc node of the mpc52xx needs to be loaded with the IPB bus frequency,
not the XLB frequency.
This patch depends on the previous patches for MPC52xx device tree support

This patch adds support for the Prodrive P3M750 (PPC750 & MV64460)
and the P3M7448 (MPC7448 & MV64460) PMC modules. Both modules are
quite similar and share the same board directory "prodrive/p3mx"
and the same config file "p3mx.h".

In the bootvx command the load address was only read from the env
variable "loadaddr" and not optionally passed as paramter as described
in the help. This is fixed with this patch. The behaviour is now the
same as in the bootelf command.

Patch below corrects the setting of the zmiifer register, it was

The current NAND Bootloader setup forces the environment
variables to be in line with the bootloader. This change
enables the configuration to be made in the board include
file instead so that it can be individually enabled.

Two fixes for the nand_wait() function in
drivers/nand/nand_base.c:
1. Use correct timeouts. The original timeouts in Linux
source are 400ms and 20ms not 40s and 20s
2. Return correct error value in case of timeout. 0 is
interpreted as OK.

This patch allows an arch/ppc kernel to be booted by just passing 1 or 2
arguments to bootm. It removes the getenv("disable_of") test that used
to be used for this purpose.
