from Steven James baremetal in LinuxBIOS, also add the OHCI support.


1. refer to README.filo
        but don't need to use make config. 
2. CFLAG added
        CONSOLE_BTEXT --- for btext console support
        CONSOLE_PC_KBD  --- for direct pc keyboard support
        CONFIG_FILO     --- It will make main call pci_init
3. to make:
        make bin/filo.zelf
    or

   You can not use filo and ide_disk at the same time.
