V2 VIA EPIA

[Andrew Ip]

Hi Ron,

I'm able to build and run LinuxBIOS on EPIA with some treaking on Config.lb.
However, it fails to jump to payload(etherboot).  I suspect LinuxBIOS is
jumping to a wrong location.  Is it possible to set ZKERNEL_START in v2?
BTW, ROM_SIZE for default setup should be 262144 instead of 512k, since
most EPIA doesn't come with 512k flash.
