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.
