Linux: Dm8148

Tool/software: Linux

I have a Dm8148's board.This board's memory is 1GB in total.I want use 512M memory in the method of noninterlanced.

I find some information about DM8148's memory allocation,but all of them is allocating memory in the method of interlanced.

I don't use this method,because I have two block memory,each of them is 512M.

So I can only use one block memory for my goal.But I don't know how to allocate memory in uboot. And I need modify which files.

I wish to get your help.

Thanks.
