Hi all,
I've updated our linux-omap tree to v2.6.32-rc1. I've also
added a branch omap-2.6.31 for the old code.
This time I also nuked the remaining omap legacy code we
still had lurking around :) The commits at the end of this
mail describe what I did first as commits, then I merged
everything to be the same as the mainline v2.6.32-rc1.
So currently the linux-omap master branch is:
v2.6.32-rc1 + omap-fixes + ehci + cbus
The new model is that I'll be resetting the linux-omap master
branch to mainline at each -rc, then merge in our various
upstream queues back in again.
Excellent! I was wondering why this wasn't being done. I certainly
hope linus' 2.6.32 will work on omap right away.
Yeah, let's hope Tomi gets in the DSS2 code too.
Anyway, I haven't been able to make 2.6.31 boot on beagleboard, and
other people report similar issues:
http://www.spinics.net/lists/linux-omap/msg17968.html
Have you got 2.6.32-rc1 (+fixes) to boot?
Hmm, looks like it's musb again. This is what I get on my
overo after applying the DEBUG_LL hack from omap-debug branch:
i've just sent a fix for this musb problem. patch is labelled "twl4030: Fix boot
with twl4030 usb transceiver enabled"
cheers,

What are you getting with DEBUG_LL enabled and the associated patch applied
from omap-debug branch?
