Fix auto_update for MCC200 board.
The invocation of do_auto_update() is moved to the end of the
misc_init_r() function, after the flash mappings have been
initialized. Please find attached a patch that implements that
change.
Also correct the decoding of the keypad status. With this update, the
key that will trigger the update is Column 2, Row 2.
CAM5200 flash driver modifications:
- use CFI driver (replaces custom flash driver) for main 'cam5200' target
- add second build target 'cam5200_niosflash' which still uses custom driver

[PATCH] nand: Fix problem with oobsize calculation
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.

Few V38B changes:
- 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)

In the bootvx command the load address was only read from the env

in the help. This is fixed with this patch. The behaviour is now the
same as in the bootelf command.

The current NAND Bootloader setup forces the environment

mpc83xx: Fix the incorrect dcbz operation
The 834x rev1.x silicon has one CPU5 errata.
The issue is when the data cache locked with
HID0[DLOCK], the dcbz instruction looks like no-op inst.
The right behavior of the data cache is when the data cache
Locked with HID0[DLOCK], the dcbz instruction allocates
new tags in cache.
The 834x rev3.0 and later and 8360 have not this bug inside.
So, when 834x rev3.0/8360 are working with ECC, the dcbz
instruction will corrupt the stack in cache, the processor will
checkstop reset.
However, the 834x rev1.x can work with ECC with these code,
because the sillicon has this cache bug. The dcbz will not
corrupt the stack in cache.
Really, it is the fault code running on fault sillicon.
This patch fix the incorrect dcbz operation. Instead of
CPU FP writing to initialise the ECC.
CHANGELOG:
* Fix the incorrect dcbz operation instead of CPU FP
writing to initialise the ECC memory. Otherwise, it
will corrupt the stack in cache, The processor will checkstop
reset.
