fpga for 7010 device may need reworking about oh HOT 4 OPEN

Just to let you know I have just completed a quick test, using hdmi to display a good image on the screen, running the speaker-test to listen to a rather high pitched left / right speaker test PLUS running my interrupt driven emailbox / memory test...

and it all works (kind of).. the corruption on the sound is no doubt because I am using the wrong reference clock speed. I will experiment a bit but it looks good on a xc7z020clg400-1 part and I have every hope that the xc7z010clg400-1 will also work.

The following output shows the interrupts cdns-i2c and f8003000.ps7-dma are I guess sound related because the counts increase quite a bit each time I do the sound test, 80000000.esaxi is the elink mailbox, hdmi interrupt although wired in is not in the device tree and seems not be be used by the ADI drivers at present (ie they seem to use cdns-i2c) and I am not sure why the video dma interrupt is not showing count but then perhaps I have got something else not quite right or perhaps it is only used with video rather than still images.. anyway a bit of a success thanks to your hard work!

Very cool! I am looking into clocking to see if we can use 1 less pll.

Perhaps scarce resource should be outside the main block so that a user may use other outputs from the same clocking source?

Sound on 7010 - Snookered! I dont want to change the boot loader so I am stuck with the FSBL configured clock speeds. Never mind. At least the 7010 board hdmi has a chance of working now that the oh fpga builds for that.
