Re: [Xen-devel] [PATCH] xen/arm: Support kick cpus and switch to hypervisor for the OMAP5

I use the u-boot_2013.01.1.1 shipped with TI and patched commit c4a4e2e
of the mainline u-boot.

And I think the latest upstream u-boot should work too, since it already
has that commit. And a netbsd guy told me the upstream u-boot works for
him.

Cheers,

Baozi
