[U-Boot-Users] [PATCH 0/9] NAND update
William Juul
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 and drivers.
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. We intend to submitt a YAFFS patch after this
patch has been submitted/accepted.
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

We have set up a git repository were you can pull the patch:
http://git.tandberg.com/tandberg/u-boot.git
Since my last email to the list I have cleaned up some coding style issues
as requested by Stefan Roese.
The master branch is tracking the official u-boot.git master branch.
The branch mtd-update-1.3.0-rc3 is based on tag v1.3.0-rc3
The branch mtd-update will (to some degree) continue to track u-boot updates.
The file drivers/nand/nand_base.c contains the struct nand_oob_128 which
is not (yet) part of Linux mtd. I will try to figure out if this implementation
is valid by asking on the linux-mtd mailing list.
Note that the following patch-series is broken unless it is seen as one single
patch. It is broken up to multiple emails to fit the size limit. This patch
series is based on a diff against v1.3.0-rc3.
Best regards
