The new part supports 1080p video and has the ARM running at 495MHz. More SoC information: http://focus.ti.com/docs/prod/folders/print/tms320dm6467t.html Spectrum Digital, Inc has a new EVM for this part. It is _mostly_ same as the older DM6467 EVM except for a 33MHz crystal input and THS8200 video encoder for 1080p support. The meat of this patch is dedicated to initializing the crystal frequency from EVM board file. Additional notes: I did consider some alternative ways to make the crystal input board specific including - (1) having board code initialize the crystal frequency using the first member of soc_info->cpu_clks array (2) introducing a new ref_clk_rate member in soc_info structure. But, the current way seems to be the simplest and least intruding considering that both the clock array and SoC info structure are actually private to the SoC file. Also the fact that davinci_common_init() initializes both the soc_info and clocks in one go.
