在 drm 设置成 1920x1080 的,
fbset 显示是没有错的，
fb-test-rect 测试程序显示正常。

5.2 TCON
This section describes the timing controller of A33 platform.
5.2.1 Overview
• Support LVDS interface with single link, up to 1280X800@60fps
• Support RGB interface with DE/SYNC mode, up to 1280X800@60fps
• Support serial RGB/dummy RGB/CCIR656 interface, up to 1280X800@60fps
• Support i80 interface with 18/16/9/8 bit, support TE, up to 1280X800@60fps
• Supported pixel formats: RGB888, RGB666 and RGB565
• Support dither function from RGB666/RGB565 to RGB888
• Support Gamma correction with R/G/B channel independence TCON只支持 1280X800 ?
貌似是TCON 的问题？

理论上TCON只是一个时序发生器，应该不会造成死机。
