I'm working on a custom board that requries a change to the memory map

sources and the configuration files where the memory locations are set
but the ltib menu does not give access to these settings. Changing
them in the configuration or source files just results in the ltib
over writing those changes prior to performing the build.

I want to do this correctly with the tool. REALLY FRUSTRATING.
DOCUMENTATION SUCKS EGGS!! I know there's a way to do this it's not
clear how. Any help much appreciated....

LTIB will build your kernel image and create a root file system image,
but does not change any kernel code. You will have to modify the
supported board's code for your custom board.


I figured out what I needed to do. The BSP I'm using has a menu
interface (like busybox) but you couldn't select the thing I needed to
change (SDRAM_BASE, FLASH_BASE). When I would change these in the code
LTIB would just change them back. I found that if I
changed these in the kConfig file of my platform the changes would be
passed into the code.

My biggest question is if I can remap the memory for Linux this way.
It seems to want SDRAM to start at 0x0 and Flash to start at a higher
address (0xF0000000 in this case). My board requires Flash to start at
0x0 and SDRAM at 0x30000000. I've changed the values but I
still don't have the thing booting (does nothing). That's my real
issue.
