This series adds support for the Tegra2x's display peripheral. This supports the LCD display on Seaboard and we use this to enable console output in U-Boot on the LCD.

- The display works fine for cold boot, or hitting the physical reset
button, but when I execute "reset" at the U-Boot prompt, or "reboot" within Linux, the display is messed up; it looks like the LCD isn't able to sync to the timings sent by the display controller or something similar.
Since this is slightly a corner case, it may be OK to fix it later (but not much later; reboot is very useful to me.)
A couple more points:
BTW, I tried the same tests on Springbank which is basically Seaboard with a slightly different PCB layout, and didn't see this issue. That leads me to suspect some timing issue interacting with the panel, which I believe is different albeit theoretically compatible resolution/scan-timing wise.
Second, I first applied Tom's Tegra30 patches and tested those, then applied your LCD series. The LCD series as-is breaks compilation of the Tegra30 support. I have no idea which order Tom might apply these in, but this is a heads-up there will be conflicts and one needs to be rebased on top of the other.
