This patch add the RTC_LIB support for fuloong2e,fuloong2f. To make hwclock work with it normally, please do: kernel configuration: Device Drivers ---> <*> Real Time Clock ---> <*> PC-style 'CMOS' user-space configuration: $ mknod /dev/rtc0 c 254 0 /dev/rtc0 is the default RTC device file. of course, if udevd is installed, ignore the above user-space configuration.
