Hello,
Here is my set of 7 patches adding support for the BT Home
Hub 2B. The last three are patches to the OpenWRT source tree.
The others I have left as diffs of the kernel or fstools sources,
because if you accept them I don't know whether or not you will
want to merge them with other patches. But do please let me know
if there are problems with the format, or if any other changes
are required.

PATCH 1/7 - Adds support for nand flash to mtd split code.
Identifies a jffs2 partition by looking for the
cleanmarker in the oob.
Required for a working all-jffs2 image.
PATCH 2/7 - Adds support for nand flash to fstools.
Identifies a jffs2 partition by looking for the
cleanmarker in the oob.
Required for a working squashfs image.
I am aware that using squashfs on nand is not
recommended because of the lack of error correction.
But at the moment a squashfs image can be generated
and booted, and the overlay filesystem is created
OK, but on reboot the jffs2 partition is not
recognised, meaning that changes to configuration
files are lost. My reasoning was that if someone does
use a squashfs image, despite the risks, then it might
as well be made to work. Or perhaps you have other
solutions in the pipeline?
PATCH 3/7 - xway nand locking
As a result of changeset 40310, the xway nand driver
now acquires ebu_lock in the chip select function, and
holds it for the entire duration of an operation until
the chip is deselected. There is surely no longer any
need therefore to acquire the lock in each separate
read or write function. This patch removes that code.
PATCH 4/7 - xway nand interference with pci.
Prevents interference between pci and nand by disabling
pci req lines during nand operations, and introducing
some additional waiting. This new behaviour can be
turned on or off by means of an option in the device
tree.
This is an updated version of following patch:
http://patchwork.openwrt.org/patch/4746/
PATCH 5/7 - Lantiq nor patch. Adds support for jedec probing if cfi
probing fails.
PATCH 6/7 - Board support patch for BT Home Hub 2B (Requires at
least one of patches 1 and 2, preferably both, plus
patches 3, 4, and 5.)
PATCH 7/7 - Basic user space configuration for the BT Home Hub 2B.
