This adds some support for ARM as well as 64-bit. 64-bit on PowerPC is currently not working, and ARM support has not been completed or tested on the FreeBSD side. As this was imported from a Linux tree, it includes some Linux-isms (ioread/iowrite), so compile with the LinuxKPI for now. This may change in the future.
