RFC cpm2_devices DPRAM resource

[Allen Curtis]

Slightly different question than the current thread:

Should the DPRAM appear as it's own platform_device?
Option 1) Specify the portion of the DPRAM used by each device with 
that platform_device definition. (current)

Option 2) Define the whole DPRAM region as its own platform_device 
entry. Move the device DPRAM information to the device specific 
platform structure.

Would this help with a general dpalloc() implementation? It would 
reduce the number of ioremap() regions.

Another thought.
