FYI... I tested this branch on my 4430ES2.1/Panda and got an infinite
loop of L3 errors.
I haven't debugged which patch causes the problem, but thought you'd
like to know. I did notice that that booting v3.3-rc1, I see
[ 0.309478] omap_hwmod: ipu: failed to hardreset
but booting your branch I see a few more reset failures:
[ 0.308532] omap_hwmod: dsp: failed to hardreset
[ 0.328979] omap_hwmod: dsp: failed to hardreset
[ 0.358001] omap_hwmod: ipu: failed to hardreset
[ 0.378448] omap_hwmod: ipu: failed to hardreset
[ 0.398895] omap_hwmod: ipu: failed to hardreset
[ 0.427520] omap_hwmod: iva: failed to hardreset
[ 0.447967] omap_hwmod: iva: failed to hardreset
There's a full boot log below.
I noticed you tested on Panda too, but one difference between our setups
is probably that I'm not using u-boot. Instead, I'm booting over USB
using the usbboot tool written by Brian Swetland:
git://github.com/swetland/omap4boot.git. It could be that the
different bootloaders are leaving the other IPs in different states.

Uncompressing Linux... done, booting the kernel.
