That would be a huge help.
This (attached) patch adds DMA read support. Due to issues with the
M2M-DMA driver, the m2m is exclusively used for sdcard support only.
The dma driver will require some re-engineering to be used "on the fly"
for doing things like sdcard / nand flash / etc.
I would suggest building a kernel from scratch following this procedure:
1) Get a copy of 2.6.27.31; untar.
2) Download Matt's patch set for 2.6.27.x - apply all patches in the
patch directory first. These are obtainable from the ts-7000 yahoo group.
3) Apply the attached patch (after unzipping).
4) Use your standard config file (if you have one) for 2.6.27 (one from
29 will probably work as well). Configure to enable ts sdcard support
in the drivers/block sub-directory.
You _may_ just be able to run the attached patch on a 2.6.29 source
directory - but I haven't tested this; so it may not work.
If compilation goes successfully, you should be able to directly boot
from an ext2 / ext3 filesystem on an arbitrary sdcard partition. I do
this by specifying the kernel configuration line in the kernel config.
I will produce a web page on how to build such a system shortly; but
getting an svn up with kernel support; etc will likely make progress
much easier.
Cheers,
-Brett
