uart: Redefine Kconfig options
Option DRIVERS_UART builds with support for UART hardware. Option CONSOLE_SERIAL enables the console output for UART. Those x86 boards that do not have serial port on SuperIO should select NO_UART_ON_SUPERIO to disable 8250 UART for the default configuration. Removes: CONSOLE_SERIAL_UART HAVE_UART_IO_MAPPED HAVE_UART_MEMORY_MAPPED Renames: CONSOLE_SERIAL8250 -> DRIVERS_UART_8250IO CONSOLE_SERIAL8250MEM -> DRIVERS_UART_8250MEM Change-Id: Id3afa05f85c0d6849746886db8b6c2ed6c846b61 Signed-off-by: Kyösti Mälkki <kyosti.malkki@gmail.com> Reviewed-on: http://review.coreboot.org/5311 Tested-by: build bot (Jenkins) Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
