[kvm-ppc-devel] [PATCH] kvm(ppc)-userspace: initialize virtio-block

[ehrhardt@linux.vnet.ibm.com]

From: Christian Ehrhardt <ehrhardt@linux.vnet.ibm.com>

virtio-block support is atm initialized in qemu/hw/pc.c which is only called
for the "standart pc" platform.
In our case we need to call the virtio-block initialization from our platform
init. It might be worth  moving this initialization into a funvtion in 
virtio-block.c and only call that initializer from any platform init that
supports virtio - any suggestions/preferences if we should do it now or when
another architecture needs that - Anthony ?

This patch adds that initialization for the kvmppc bamboo platform.
