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.
Configuration is via the device tree. Proposed bindings are included
in this series.
To improve performance two optimisations are offered:
1. The LCD frame buffer is cached, with the cache being flushed after
each call puts(). This dramatically increases performance (around 10x).
This requires a few additions to the ARM cache support.
2. The console supports scrolling in steps of more than 1 line. This
speeds up scrolling output considerably, particularly commands like
'printenv' which display a lot of output. This requires a new CONFIG
and a change to the console_scrollup() function.

Hi Simon,
I have added your patch sources manually into the "Prepare v2012.04-rc1
release", because I got errors at apply. Also I added a device tree
source file for Harmony.
I tested the device tree source file for Harmony and your patch sources
on our Harmony hardware and generated a new patch file:
http://poeggi.dotsec.net/nvidia/uboot-lvds-init-patch/0001-Add-display-driver-and-LCD-support-for-Harmony-board.patch
I hope it's all okay, this my first patch release.
In the display.c source file I implemented a bug fix, because I get
garbled images on the LCD without this fix.
Greetings
Christian
Changes:
- Add device tree source file for Harmony board
- Add bug fix in display.c
- Patch based on the "Prepare v2012.04-rc1" release
