AMD/bettong: Add UART support
The function delay in uart8250mem.c is not enough for hudson. I guess
there are some problems in lapic_timer(). I uploaded a patch to gerrit
to show the way to enable UART feature.
http://review.coreboot.org/#/c/12343/4
Currently the HUDSON_UART is unchecked by default. Select HUDSON_UART to
enable this feature.
The UART is test at BIOS stage.
Since it is not a standart UART device, the windows internal UART driver
doesnt support it. I guess we need a driver to use it on windows.
