This code reads the PLL configuration registers and correctly programs things so the UART and such can come up. There's MIPS74k platform issues that need fixing; but this at least brings things up enough to echo stuff out the serial port and allow for interactive debugging with ddb. Tested: * AR71xx SoCs * AR933x SoC * AR9344 board (DB120) Obtained from: Qualcomm Atheros; Linux/OpenWRT
