HimalayaLCD
From XDA-Developers
The LCD must be switched on using the ATI chip. the following code fragment does that.
absolutely no idea what these values are. the ASIC3 GPIO B outs switch off some unknown but LCD-power-related GPIO bits, then a pause is needed, then they can be re-enabled. seems to work.
except that the virtual memory address had to be mapped from 0xab010000->physical address 0x08010000 to 0xf5010000 -> physical address 0x08010000 because the linux arm kernel only supports 0xf0000000 to 0xc0000000 for device virtual memory addressing wot a pain.
This was sufficient information for D Bently to identify the chip as an ATI 3200, for which he has written a first version of an Imageon Accelerated driver. Apparently, the Toshiba e72x series uses the same chip, which does MPEG and everything.

From the WinCE ROM we got the following register names for the ATI chip:
