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.

Update MTD to that of Linux 2.6.22.1
A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.
This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.
MAKEALL ppc/arm has some issues:
* DOC/OneNand/nand_spl is not building (I have not tried porting
these parts, and since I do not have any HW and I am not familiar
with this code/HW I think its best left to someone else.)
Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:

Bitmaps with odd-numbered width won't be rendered
correctly and even U-Boot crashes are observed on
some platforms while repeated rendering of such
bitmaps with "bmp display". Also if a bitmap is
rendered to an odd-numbered x starting position,
the same problem occurs. This patch is an attempt
to fix it.
If logo_plot() should ever be called with x starting
position other than zero and for pixel depths greater
than 8bpp, logo colors distortion will be observed.
This patch fixes the issue.
While locally preparing some U-Boot patches for ARM based OMAP3 boards, some
using OneNAND and some using NAND, we found some differences in OneNAND and
NAND command address handling.
As this might confuse users (it already confused us), we like to align OneNAND
and NAND address handling.
The issue is that cmd_onenand.c subtracts the onenand base address from the
addresses you type into the u-boot command line so, unlike nand, you can't
use addresses relative to the start of the onenand part e.g. this won't work:
The commit was based on a misunderstanding of the (documented)
meaning of the 'autostart' environment variable. It might cause
boards to hang if 'autostart' was used, with the potential to brick
them. Go back to the documented behaviour.

The CFI driver allowed only for static initializers in the

U-Boot allows for configurable prompt strings using the
CONFIG_AUTOBOOT_PROMPT resp. CONFIG_MENUPROMPT definitions. So far,
the assumption was that any such user defined problts would contain

To allow for flexible boot prompts without adding too complex code we
now allow to specify the whole list of printf() arguments in the user

really understands what he is doing, as he needs to know for exanple
which variables are available in the respective context.

Fix compile warnings in dlmalloc
The origional code was using on odd reference to get to the first

warnings:
dlmalloc.c: In function 'malloc_extend_top':
dlmalloc.c:1971: warning: dereferencing type-punned pointer will break strict-aliasing rules
dlmalloc.c:1999: warning: dereferencing type-punned pointer will break strict-aliasing rules
dlmalloc.c:2029: warning: dereferencing type-punned pointer will break strict-aliasing rules

bin_at(0) = (char*)&(av_[2]) - 2*SIZE_SZ
SIZE_SZ is the size of pointer, and av_ is arry of pointers so:
bin_at(0) = &(av_[0])
Going from there to bin_at(0)->fd or bin_at(0)->size should be straight forward.
