At previous time LSI guided that you should use the 0x3000'0000 for MFC issues. And please keep the consistent If you commit this one. we have to change the our environment from bootloader and kernel. Now we use the local kernel and mainline. Also how can you use if we got the 0x2000'0000 with 128MiB and 0x4000'0000 with 384MiB or 512MiB. There's too much memory holes. Please don't say use the split the user and kernel 2G/2G configuration If we modify the base address, we can use above memory configuration without any changes.
