Hi
I am currently working on MPC8548 core, would like to know wheather current
Linux with e500v2 core supporting Physical Address of RAM at 0x1_0000_0000,
I know in current linux with large Page table support we can access devices
at 0x1_0000_0000 for e500v2, but I wanted to move RAM base address to
0x1_0000_0000, so that I can support larger RAM. Can any body suggest me if
their is any patch available for this or is it possible to implement from
scratch.
Thanks
Subbu

The HW supports this. I don't believe there is any code that exists
today that sets this all up.
