Linux 2.6 frame buffer for XUPV2P

[mingqian]

Thanks Grant!
    It works after I follow your advice 1) & 2). The small Linux logo is shown on the screen,

And I got the following from dmesg:
xilinxfb: calling of_register_platform_driver()
xilinxfb a08f8b00.tft: xilinxfb_of_probe(dfaaee00, c02bfde0)
Console: switching to colour frame buffer device 80x30
xilinxfb a08f8b00.tft: fb: phys=1f000000, virt=ff100000, size=1e0000


Best Regards & Merry Christmas!
