Although we have hp t410 booting, I noticed that dm814x-evm does not boot after I got one. This is because we don't have the clocks yet configured properly. Let's start configuring proper clocks starting with the system timers and clocks that work with existing mux and divider clock drivers. Note that the oscillator speed register is different from am335x, dm814x has only one bit that shows the BTMODE[6] at CONTROL_STATUS[21]. Also note that this only gets the system timers working with the defined clocks. The PLL clocks are still missing and and the devices may or may not work depending on what the bootloader has enabled.
