I am porting the ecos kernel to S3C44B0X samsung board. the memory layout of which is
shown above. I wanted to write the memory layout files for this. What are the steps I
should follow and what are the other things i have to consider while writing them

If your memory doesn't start at 0x0 your going to have a certain amount of difficulty with the ARM port. Unfortunately the ARM architecture HAL has got a limitation of assuming RAM starts at 0x0. You'll need to make some long-needed improvements to the ARM arch HAL to achieve this I'm afraid.
