FO 10:57 PM Feature #85: 720p support/1080i support

Its opcodeInfoTable that is getting put into altsyncram. Not sure why its invalid yet. I'm trying the ramstyle attribute but didn't find the right voodoo yet... foft

On v1 its all working, with 32K block ram as system ram. Once I put it to 64K block ram as system ram (which JUST fits) I never get to basic. After some playing with the logic analyzer (tricky, no block ram!) I can see that at C4F1 the C... foft

Got this merged down to svn and also v1 and v3 building.
Was hanging on purely internal i2c. Changed master and slave (+glue) to use in/wen instead of inout and working better. Slightly corrupt output on v1. I think this might be due ... foft

FO 10:24 PM Feature #85: 720p support/1080i support

I have the crtc/scaler settings now in the flash chip (except scaler filter).
Upside: doesn't waste space in firmware
Downside: people will need to flash with usb blaster, rpd method will brick the video. foft

Oh and the clkgen chip can drive the video too, for those who want to try custom modes. I've not tried it yet since its statically set up at 30MHz iirc, but should give it a spin. foft

FO 09:25 PM Feature #85: 720p support/1080i support

I have all these modes working properly from the firmware.
NTSC:480i/480p/720p/1080i
PAL:576i/576p/720p/1080i
All in 4:3
480p/576p and 720p all skip a pixel, so 4x gr.0 or gr.8 isn't great.
480i and 1080i do not! Yes, 480i is bett... foft

It seems pretty clear that on the 2nd board can use the reconfigurable clock to provide 27MHz and 74.25MHz hdmi clocks, by reconfiguring it. These can drive clk6p into the 3rd pll, which does x5 for the tmds clk (/2).
For the others..... foft

Clock switching is proving fun, due to a bunch of constraints!
1st board: 50MHz on H16 (CLK11p) - which is connected to FPLL X0_Y38,X54_Y38, but not the other two
