* ARC: Dynamically determine BASE_BAUD from DeviceTreeVineet Gupta2015-02-021-18/+5
| | | | | | | | | | | | | | | | | | 8250 earlycon is broken on multi-platform ARC because the UART clk value (BASE_BAUD) is fixed at build time. Instead, determine the appropriate UART clk at runtime; parse the devicetree early for platforms requiring alternate UART clk values (currently only the TB10X platform).
