Before: The timeout value for sata harddisk was 1000ms, that was too short for
some sata harddisks. It caused the problem as Bug 524 described as
http://www.loongson.org/dev/bugzilla/show_bug.cgi?id=524 showes.
Now: The timeout value is 2000ms, it is long enough for all sata harddisks.
Test: Disconnect power for 30s, then connect power and start up, repeat it for
20 times at least.

Now ohci usb mode support is added, both usb keyboard and usb disk
are ok. However, only DELL usb keyboard pass test. It's said this
is maybe becuase the usb signal is not very good.Thanks ZangJiading.
NOTICE:if BIOS option "INTERFACE_3A780E" is removed, usb keyboard
will fail to use, becuase some usb keyboard poll code won't be executed
if micro "INTERFACE_3A780E" isn't defined. By the way, the option
"INTERFACE_3A780E" has no relation with RS780E, it's used to mean
BIOS MENU and windows interface is enable.

Before: In DMA mode, PMON can not load the small-capacity of hard sata
(0-137G). It caused the problem as Bug 231 described as

small capacity of sata(0-137).

small-capacity of hard sata (0-137G).
