78b65179d0 [MTD] [NAND] Don't panic if a controller driver does ecc its own way.
Some hardware, such as the enhanced local bus controller used on some
mpc83xx chips, does ecc transparently when reading and writing data, rather
than providing a generic calculate/correct mechanism that can be exported to
the nand subsystem.

The subsystem should not BUG() when calculate, correct, or hwctl are
missing, if the methods that call them have been overridden.

 - compare against plat->page_size in 2 cases when enable hardware ECC

ChangeLog from try#2
 - passed nand_test suites
 - use cpu_relax() instead of busy wait loop
 - some coding style issue pointed out by Andrew

98b830d260 [MTD] [NAND] nandsim: avoid deadlocking FS
Make nandsim use GFP_NOFS when allocating memory, because it might
be used by a file-system (e.g. UBIFS2) which means, if we are short
of memory, we may deadlock. Indee, UBIFS is holding a lock, writes
to the media, reaches this place in NANDsim, kmalloc does not find
the requested amount of RAM, calls memory shrinker, which decides
to writeback inodes, calls FS, and it deadlocks on the lock which
is already being held. Below is the UBIFS backtrace which
demonstrates that:

The deadlock is funny because it starts in pdflush/writeback,
and comes back to writeback, then deadlocks. It seems we should look
carefully for other places in UBI and MTD and use GFP_NOFS instead
of GFP_KERNEL.

e208520ed6 [MTD] [NAND] Driver for Olympus MAUSB-10 and Fujifilm DPC-R1 card readers
Unlike most stuff on the market the chip inside these two allows raw
flash access and doesn't implement and FTL, leaving that functionality
to the device driver.

Raw flash access in a cheap USB cardreader!  An MTD test device one can
attach to a PC!  What a deal!

The command set of the chip is not documented, so information was
obtained from the existing mass-storage driver
(drivers/usb/storage/alauda.c), its documentation
(http://alauda.sourceforge.net/wikka.php?wakka=BulkCommandReference),
additional reverse engineering and comparison with a vendor driver for a
related chip
(http://www.ratocsystems.com/english/download/driver/linux/sma03u.html).

4a32cfa0f5 [MTD] [NAND] Fix refactoring of EDB7312 hwcontrol function.
The patch ensures that the current code (kernel 2.6.22) uses the bits 
like the code prior to the refactoring. The variable "bits" is employed 
in a useful way now.

8f46c527ac [MTD] [NAND] cafe_nand.c: the OLPC laptop is not available for $100
The price might drop to $100 in a few years.

But currently, a more reasonable name might be "$175 laptop".

Let's simply call it "OLPC laptop" without any price tag.

This patch adds 405 platform support to the 440 NDFC driver. The new
AMCC 405EZ PPC is equipped with the same NDFC core as the 440EP(x)
and other will follow soon.

8b099a390d [MTD] [NAND] nand_base.c: fix type of eccpos pointer
The nand_base.c driver implicitly casts the uint32_t
eccpos array to 'int *', which is not only not guaranteed
to be the same sign as the source, but is not guaranteed
to be the same size.

Fix by changing nand_base.c to use uint32_t
referencing the eccpos fields.
