Re: [kvm-ppc-devel] [kvm-devel] [PATCH 0 of 7] PowerPC Embedded KVM

[Jerone Young <jyoung5@us.ibm.com>]

The issue here is that qemu does not support u-boot firmware. What we
are doing is actually loading a u-boot image and booting Linux directly
with a pre made device tree (which is something normally u-boot firmware
would provide Linux). So this code wouldn't fit into plain qemu just
yet.
