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.
