[U-Boot] Machine check exception on video driver initialization

[Thirumalai]

Hi Stefan,
            I am getting Machine check exception when my video driver is 
initializing. When i searched the net i found that you also faced the same 
kind of problem. I have mentioned the VIDEO_IO_OFFSET as 0xf0000000. This 
address is nothing but CONFIG_SYS_PCI1_IO_VIRT which is mentioned on my 
config file.

Here the log of my output.
