I've been trying to modify the kernel (v2.2.1) to support a 64mb Brutus
board with 16mb in each of the 4 memory banks. These were the changes I've
made:
./arch/arm/kernel/setup.c:403: memory_end = 64*1024*1024;
and...
./arch/arm/mm/mm-sa1100.c-54-/* 4Mb per bank in this case */
./arch/arm/mm/mm-sa1100.c:55:/* Adding support to 64mb Brutus - 4096 pages
p/ bank instead of 1024 */
./arch/arm/mm/mm-sa1100.c-56-#define PAGES_IN_BANK_0 4096
./arch/arm/mm/mm-sa1100.c-57-#define PAGES_IN_BANK_1 4096
./arch/arm/mm/mm-sa1100.c-58-#define PAGES_IN_BANK_2 4096
./arch/arm/mm/mm-sa1100.c-59-#define PAGES_IN_BANK_3 4096
However, it could not fine RAM disk.

Am I missing something?
