We have a client building a PPC8548-based product who insists that we allocate DRAM real address space in two large chunks at 0-2GB and 4-6GB in the 36-bit address space. It doesn't look like U-Boot's bd_info structure allows for that, and it doesn't look like the Linux init routines (which accesses the passed table) knows how to handle discontiguous memory either (as opposed to X86 Linux, which can accept an E820 table).
The memory map is just a matter of software definiton. Ignore the silly request and map the RAM contiguously.
Any comments would be VERY appreciated.
Stop people fromn doing stupid things.
