Getting physical memory information from /proc/iomem

[Rajasekaran Periyasamy]

Hi,
I have a MPC7447A board running linux 2.6.21. I want to get the physical RAM layout from /proc/iomem, but it is not proper as of x86 platform. Here is the output of my target's /proc/iomem.

[root at rootfs ~]# cat /proc/iomem
80000000-87ffffff : PCI hose 0 MEM Space 0
  86900000-869fffff : 0000:00:02.2
  86a00000-86afffff : 0000:00:02.2
.
.

  87f00000-87f7ffff : 0000:00:01.0
  87ffffc0-87ffffff : 0000:00:01.0
88000000-8fffffff : PCI hose 1 MEM Space 0
  8d3fe000-8d3fefff : 0001:01:05.2
  8d3ff000-8d3fffff : 0001:01:05.1
.
.

  8e000000-8effffff : 0001:01:04.0
  8f800000-8fffffff : 0001:01:04.0
fbe02000-fbe03fff : ethernet shared base

  fbe0c000-fbe0c01f : mv64xxx_i2c adapter
ff000000-ffffffff : physmap-flash.0
  ff000000-ffffffff : physmap-flash.0


Can you please anybody tell me how to interpret this to get physical RAM addresses. Or is there any patch available to get the details of System RAM from /proc/iomem ??

Thanks in advance,
Rajasekaran.P
