[U-Boot] 36-bits U-Boot

[Leif Sörman]

I want to have ram memory above 4G on a freescale p4080 board since I want to test that 36-bits physical addressing is working, my board has two 2G dimm mounted.

 

The standard 32-bits u-boot on the board says that it can only handle memory less than 4G.

I have managed to flashed a 36-bits u-boot to the board and now I realized that the 36-bits u-boot

put the two gigs memory below 4G.

 

Is it possible to change something in u-boot so it put one of the memory device above 4G?

 

I think a better solution for me would be to replace the two memory devices with two 4 gigs devices.

 

Does u-boot support larger devices? 

 

Maybe it's only to put the larger memory in and everything works.
