SDHC on the dockstar

If I wire up the SDHC thing like documented here http://archlinuxarm.org/forum/viewtopic.php?f=6&t=258#p1748
and compile a kernel with support for it (supposing there is a driver for the MV88F6281 SDHC ... but the plug devices have it so I gues there is).
Will I be able to use it or will it be unavalible till u-boot tell the kernel that it's there ?

What are my options ?

David,

Dockstar uBoot does not have MMC support. So that device will not be passed to the kernel. There are 2 options:

1. Try the Pogo V4/Mobile uBoot to see if it works.

Since the Dockstar does not have UART booting, this uBoot image must be either:

a) Loaded with tftp and run it (no risk)
http://forum.doozan.com/read.php?3,6965

or

b) Flash it to mtd0 (risky, since you could brick the box and have to resort to JTAG)

2. You could look for another Kirkwood device that has uBoot board files for MMC (such as the Pogo V4/Mobile) and extract the patch. Build new uBoot image for it.

I should mention this. Since Davy has built a MMC-capable uBoot, if we can get his uBoot patch, I will build a new 2013 Pogo V4/Mobile uBoot image for general consumption. And will build the MMC-capaple uBoot for other Kirkwood boxes on request. Davy has not been here around lately so I don't know if we can get the patch.
