Has anyone setup u-boot to configure more than 2gig of main memory?

Where does u-boot go in the 36 bit world.

is it possible to configure 2gig on each DDR controller of the MPC8572 and have u-boot run right out of the box?

I know u-boot load itself way out at the end of memory, but in this case, that would be 0x1-fff8-xxxx

In practice this should work with the latest u-boot (v2009.01). Additionally, changes have been going in for the next release v2009.03 for 36-bit physical on 8572.

I was going to try putting 4G of DDR in a MPC8572 DS tomorrow. I'll let you know what happens.
