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:
cpu/ppc4xx/ndfc.c
cpu/arm926ejs/davinci/nand.c
board/delta/nand.c
board/zylonite/nand.c

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.
