How to set dram region to cacheable?

Note: This was originally posted on 31st October 2012 at http://forums.arm.com

hi, experts:
I am a newcomer to ARM world.
I was working x86 platform in these years.

So, i have a question about how to set dram region's cacheable attributes.
Take my ARM development board as an example:
It has 1GByte DRAM, 4MB NOR Flash, 64MB Nand Flash.
So:
1. How to set some parts of 1GByte DRAM to cacheable(write back)?
2. How to set 4MByte NOR Flash region to cacheable , to enhance uboot's execution speed?

With x86 CPU, it had MTRR registers to do these things, so how to do these things on ARM platform?
I have read some arm documents, it seemed doing these things by creating page tables , right?

Any tips will be appreciated!

best wishes,
