[Qemu-devel] [PATCH v3 0/7] Allwinner A10 fixes

[Beniamino Galvani]

This series introduces some fixes and missing features found while
trying to run mainline Linux kernel on emulated Allwinner A10.

Most of the changes concern interrupt handling, but there are also
improvements in the timer and the ethernet MAC.

With this applied I'm able to boot Linux 3.14-rc2 using a NFS root:
