Hello!

Yes, it seems the dts file is specified at line 97, and the 
std.db88f6xxx is at line 8. Perhaps these need to be modified, 
yes.

U-Boot announces the amount of DRAM to 128MiB, and 256MiB of 
NAND. Is there any U-boot command I can run to show some of the 
memory mapping to determine the new addresses?

I looked around and at least found the commands cmp, md, and 
bdinfo, perhaps they are useful:

| Marvell>> help
| bdinfo  - print Board Info structure
| cmp     - memory compare
| md      - memory display
| Marvell>> cmp    
| cmp - memory compare
| 
| Usage:
| cmp [.b, .w, .l] addr1 addr2 count
| Marvell>> md
| md - memory display
| 
| Usage:
| md [.b, .w, .l] address [# of objects]
| Marvell>> bdinfo
| arch_number = 0x00000C11
| env_t       = 0x00000000
| boot_params = 0x00000100
| DRAM bank   = 0x00000000
