That's nice :)

I gave this series a quick try, it works except with all the patches
applied omap2plus_defconfig will failt to boot on omap4. It seems that
the issue is somewhere in the GIC related patches, the last one just
enables the MULTI_IRQ..
Care to give it a try on your Panda and see if omap2plus_defconfig
works for you with this series?
Looks like disabling CONFIG_SMP made it omap4 boot again.
Regards,
Tony
