This patch adds and uses #defines for PCI device classes and subclases, using a new pci_config_set_class() function, similar to the recently added pci_config_set_vendor_id() and pci_config_set_device_id(). Change since v1: fixed compilation of hw/sun4u.c Signed-off-by: Stuart Brady <stuart.brady@gmail.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6491 c046a42c-6fe2-441c-8c8c-71466251a162
