Moved from FILO into Etherboot, yhlu add boot from SATA disk and move usb boot framework 
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 
	make bin/tg3--filo.zelf

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