omap330 LCD DMA

hi, all.

I am porting linux onto a device running omap330. I need help on getting the lcd channel dma register defination. I guess that maybe in "DMA_LCD_TOP_F1_U" form , is it right? I know the framebuffer begin at 0x2000:0010,but I can't find this number in memory map range (0xfffc:0000 - 0xfffe:ffff).

Thank you in advance!
