13 * early-8250 requires BASE_BAUD to be defined and includes this header.
14 * We put in a typical value:
15 * (core clk / 16) - i.e. UART samples 16 times per sec.
16 * Athough in multi-platform-image this might not work, specially if the
17 * clk driving the UART is different.
18 * We can't use DeviceTree as this is typically for early serial.
