The lmb_dump_all() output didn't include the RMO size, which is
interesting on powerpc. The output was also a bit spacey and not well
aligned, and didn't show you the end addresses.

DaveM, if you like we could make the RMO display conditional on it being
non-zero, which would hide it on sparc presumably.

Old output:

lmb_dump_all:
    memory.cnt            = 0x1
    memory.size           = 0x80000000
    memory.region[0x0].base       = 0x0
                      .size     = 0x80000000
    reserved.cnt          = 0x3
    reserved.size         = 0x80000000
    reserved.region[0x0].base       = 0x0
                      .size     = 0xea2000
    reserved.region[0x1].base       = 0x2aa6000
                      .size     = 0xc000
    reserved.region[0x2].base       = 0x76a1000
                      .size     = 0x95f000

New output:

LMB configuration:
 rmo_size    = 0x8000000
 memory.size = 0x80000000
 memory.cnt  = 0x1
 memory[0x0]    0x0000000000000000 - 0x000000007fffffff, 0x80000000 bytes
 reserved.cnt  = 0x3
 reserved[0x0]  0x0000000000000000 - 0x0000000000ea1fff, 0xea2000 bytes
 reserved[0x1]  0x0000000002aa6000 - 0x0000000002ab1fff, 0xc000 bytes
 reserved[0x2]  0x00000000076a1000 - 0x0000000007ffffff, 0x95f000 bytes

Not necessary.
