This patch adds a full PXA270-based machine. In fact four different,
but similar models of the same series. Use "-M spitz", "-M akita", "-M
borzoi" or "-M terrier" with qemu-system-arm to select them. The board
contains a PXA processor with all its on-chip peripherals plus several
other chips including the ADS7846, MAX1111, MAX7310, WM8750, the
microdrive, NAND flash, SD slot, one usable PCMCIA socket,
touchscreen, a keypad.

There is no way to pass a kernel command line to a Linux kernel
running on this device because its stock bootloader is quite dumb. So
"-append" doesn't work. The machine is also supported by OpenBSD and
NetBSD but only Linux has been tested.

Cheers,
Andrew
