MMC broken on beagleboard with current git

Hi,

I just built a kernel from current git[1] and the mmc controller
doesn't get detected on boot on my beagleboards. The omap mmc system
has seen a lot of changes lately, does anyone have a hint where to
start looking before attemping a bisect?

regards,

Koen

Sounds like the recent mmc init changes we've done:

535e1808d1c77a580815f7d7daacc6c030e29cb1
8e6e06c71b9d21d85a3ae652868e2802c054a08a
c434c15d28c82d92e55897bd265c423e9ab69362

I've verified that it works on omap3430sdp. But mach-omap2/hsmmc.c needs
some more work done to support other mmc controllers besides the first one.
I don't think other controllers ever worked before these patches
either though..

Let me know if you can narrow it down to some commit and I may be able
to help further from there.

The previous working version I built was based of
de1121fdb899f762b9e717f44eaf3fae7c00cd3e which was commited at 13
september 2008, so 535e18.. and 8e6e06c.. don't break it.

OK, good to know. Can you try to git-bisect it?
