Marek Vašut b5e4ad57ee [ARM] 5153/1: Add support for PalmTX handheld computer
PalmTX is PXA27x based device with wifi, bluetooth,
touchscreen, sdio slot, irda, keypad, nand flash,
pxa framebuffer, serial and usb gadget interface.

Supported by this patch is pxafb, touchscreen, irda,
keypad and sdio slot.
