f3dec798d9 CFI: fix eraseregions numblocks
eraseregions numblocks was sometimes one less than actual, possibly producing
erase regions with zero blocks. As MTD code touches eraseregions only if
numeraseregions is greater that zero, allocate eraseregions only for non
uniform erase size flash.

9578718c1b mtd: cfi - if defined, use MAX_FLASH_BANKS_DETECT for static declarations
a.k.a cfi_mtd.c does as cfi_flash.c does.  This also prevents
the TQM834x build from doing a:

cfi_mtd.c:36: error: variably modified 'cfi_mtd_info' at file scope
cfi_mtd.c:37: error: variably modified 'cfi_mtd_names' at file scope

using gcc 4.4.

8d2effea23 mtd: Update MTD infrastructure to support 64bit device size
This patch brings the U-Boot MTD infrastructure in sync with the current
Linux MTD version (2.6.30-rc3). Biggest change is the 64bit device size
support and a resync of the mtdpart.c file which has seen multiple fixes
meanwhile.

0a57265533 mtd: Add MTD concat support to concatenate multiple MTD NOR devices
This patch adds concatenation support to the U-Boot MTD infrastructure.
By enabling CONFIG_MTD_CONCAT this MTD CFI wrapper will concatenate
all found NOR devices into one single MTD device. This can be used by
e.g by UBI to access a partition that spans over multiple NOR chips.

dba6fcf651 cfi_mtd: Fix bug in last sector detection
This patch now enabled this cfi-mtd wrapper to correctly detect and
erase the last sector in an NOR FLASH device.

f8e2b3107e MTD: Change cfi-mtd to accept non-uniform sector sizes
With this patch non-uniform NOR FLASH chips (chips with multiple erase
regions) can be exported via the cfi-mtd layer and therefor used by UBI.
We select the largest sector size as erasesize. The cfi driver will make
sure that the smaller sectors are handled correctly.

c203ef5db0 UBI/cfi-mtd: Fix mtd name for multiple chips
On platforms with multiple NOR chips, currently only the first one
can be selected using the "ubi part" command. This patch fixes this
problem by using different names for the NOR "mtd devices".

It also changes the name of the NOR MTD device from "cfi-mtd" to
"norX" (X indexing the device numer) to better match the mtdparts
defaults.

91809ed51d cfi-mtd: Add cfi-mtd driver.
Add cfi-mtd driver, which exports CFI flash to MTD layer.
This allows CFI flash devices to be used from MTD layer.

Building of the new driver is controlled by CONFIG_FLASH_CFI_MTD
option. Initialization is done by calling cfi_mtd_init() from
flash_init().
