Add support LCD - 320x240, 640x480, 800x480
Now working:
- ethernet cs89x0.
Boot kernel, rootfs (nfs).
- USB (usb hid, mass storage, usb to serial etc.)
- MMC/SD/SDHC.
I've tested SDHC KINGSTON 32GB (SD4).
- LCD. Support: 320x240, 640x480, 800x480.
I've tested only 640x480 (I have only 5.6" LCD 640x480)
- RTC
Current patch for 2.6.28.8 (config include)

And u-boot 1.1.6 can save env values in nand.

Nice job done!
I am thinking to have other customers of QQ2440 to make some test and comments on that. Do you agree?

On video - I use this Opie (qt)
download
Angstrom rootfs with Opie Desktop Environment rootfs. Extract/copy to SDHC and use as root filesystem.
Work (I tested):
- Video
- Ethernet
- Touchscreen
- SD
- USB (on video I connect usb flash and open jpg file)
- Bluetooth (bad video quality and I didn't include on youtube), but used usb bluetooth, and found some bluetooth devices
Now I use u-boot in NAND
u-boot load kernel from NAND in RAM, and rootfs on SDHC 32GB (I tested rootfs on USB flash - ok, rootfs on nfs - ok too.
I didn't test audio and power managment yet.
Today I installed Debian (lenny) on qq2440, it was simple and fast
Later, I will write how to install Debian to QQ2440 or mini2440 or any arm devboard
(on SD card).
