[LinuxBIOS] Re: Linuxbios is always 421bytes larger than allowed

[yhlu]

long term solution will depend 
still using romcc for 4 way and 8 way Opteron system?, if we are using
cache_as_ram we don't have a chance to make
entry32.inc+auto.inc+crt0.S bigger than 64K.

or we reorginze the map to
linuxbios_ram
auto.inc -->init section ----> it will jmp to linuxbios_ram
entry32.inc+fallback.inc----> it will call real_main at last

problem is to make use gcc to produce auto.inc and avoid the duplicate
Label problm, i already merge auto.c and failback.c into
cache_as_ram.c
