[LinuxBIOS] Merge complete....

OK. Maybe I'm the only one confused but why should the hard_reset called
from hardwaremain in C really do a soft reset.  Wouldn't it be better to
call it soft_reset?  Or maybe comment the code if hard_reset needs to do
a soft reset?  And your sure the cf9 port is enabled? Right?

stephen,

that's right. 

in auto.c stage, the hard reset is real one it will reset pci space
and ht (freq/width).
the soft reset will keep the ht (freq/width). the hard_reset is called
when ram init exception.

in the linuxbios_ram stage totally in c ( from hardwaremain, or the
root_reset_bus) is actually a soft reset, it will keep the ht
(freq/width)

the problem i met is problem ck804 doesn't reconfig ht two times.
