Subject: [PATCH] fdt_support: Use CONFIG_NR_DRAM_BANKS if defined
It appears that there are some cases where we have more than 4 banks
of memory. Use CONFIG_NR_DRAM_BANKS if it's defined to handle this.
This will take up a little extra stack space (64 bytes extra if we go
up to 8 banks), but that seems OK.
