I think that should be done in your bootcode.
If you are using u-boot, this should be part of your u-boot memory init which will init the upm, and memory map.

Not sure if PQ2 u-boot have upm, I think you can use the MPC8xx upm code as a starting point of your PQ2 upm init.

Subject: UPM driver of MPC8260

Hi all,

I am going to use UPM of my MPC8260; I need it for
handling a burstable SRAM.

I am using Wind River SBCPOWERQUICCII board. So I
think I need the configured UPM driver to be run on my

Does ELDK have UPM initialization routines for my
purpose? Can I use this machine in a service then?

Can I have this driver for any other Linux, for
example VxWorks BSP? Can I configure my driver and use
it for SRAM?

Thanks a lot,
