FAT32: fix broken root directory handling.
On FAT32, instead of fetching the cluster numbers from the FAT, the
code assumed (incorrectly) that the clusters for the root directory
were allocated contiguously. In the result, only the first cluster
could be accessed. At the typical cluster size of 8 sectors this
caused all accesses to files after the first 128 entries to fail -
"fatls" would terminate after 128 files (usually displaying a bogus
file name, occasionally even crashing the system), and "fatload"
would fail to find any files that were not in the first directory
cluster.

usb_storage.c: initialize device type
The device type was left uninitialized which caused later tests
against DEV_TYPE_UNKNOWN to fail. In the result, "usb part" would
attempt to print information about non-existent devices like this:
=> usb part
print_part of 0
Partition Map for USB device 0 -- Partition Type: DOS

## Unknown partition table

By initializing the type as DEV_TYPE_UNKNOWN we avoid all the
"Unknown partition table" messages.

will be removed in another patch.]

ppc4xx: Add "ecctest" command to test/simulate ECC errors
This patch adds the "ecctest" command to test and simulate ECC errors
(single bit and/or double bit) while running from SDRAM. Currently only
the IBM DDR2 controller is supported (405EX, 440SP(e), 460EX/GT).
This is done by copying and calling functions, modifying the SDRAM
controller operation mode, in internal SRAM/OCM.
For correctable ECC errors (single bit) only the status will be printed
since the DDR2 controller doesn't provide the faulting address:
=> ecctest 1000000 1
Using address 01000000 for 1 bit ECC error injection
ECC: Correctable error
Uncorrectable ECC errors (double bit) will also display the faulting
address:
=> ecctest 1000000 2
Using address 01000000 for 2 bit ECC error injection
ECC: Uncorrectable error at 0x0001000000
To enable this "ecctest" function you need to define CONFIG_CMD_ECCTEST
in the board config header.

ppc4xx: T3CORP fixes and updates
This patch fixes some problems for the T3CORP board. Here the list
of the changes:
- Add 600-67 and 677 CPU frequency setting to chip_config
command
- Define CONFIG_DDR_RFDC_FIXED on t3corp:
While using the "normal" auto calibration code, sometimes values for
RFDC were picked (>= T3) that resulted in a non-working U-Boot (hang
upon relocation, while running from SDRAM). With this optimized RFDC
value we can force this register and use the auto-calibration code to
setup the remaining calibration registers.
- Increase sizes of FPGA chips selects
- EBC timing updated OEN=3 for 66 MHz EBC speed
- Change ext. IRQ2 setup to level-low active
- Enable CONFIG_SYS_CFI_FLASH_STATUS_POLL
By defining CONFIG_SYS_CFI_FLASH_STATUS_POLL, DQ7 is polled to detect the
chip busy status. This is now used instead of the data toggle method which
is used historically by default in the common CFI driver. With this change
a problem with not written data is solved on this board, where a 32 byte
block of data is still erased instead of filled with the correct content
after these commands:
=> erase 0xfc100000 +0x1000000
