.Split TTY in order to support both x86 and ARM.
.Add support for the TI 16750 UARTs on OMAP35x.
.Various other improvements:
.Kernel messages are printed using generic terminal write
functions. That is, they are no longer directly displayed
on the console.
.The console can now be displayed on any terminal. This
is configured by the "console={tty00,tty01,ttyc2,ttyc3,ttyc4}"
boot variable -- basically any valid /dev/tty* terminal.
.Cutify kernel messages with colors. Configured by
"kernelclr={1,2,3,4,5,6,7}" boot variable.
