Sun Jun 13 15:00:16 EDT 2010
Add support for the HP t5325 Thin Client. This thin client is based
on a Marvell Kirkwood chip at 1.2 GHz and features 512 MB RAM, 512 MB
SATA-attached flash and an XGI Volari Z11 GPU.

This patch doesn't take Saeed's PCI changes into account; also, it
requires a mach-types update to build.
