You mean a simple search for "physical memory" like this one:

http://lists.linuxppc.org/results.html?restrict=linuxppc-embedded&words=physical+memory

didn't give you any results? Strange... I get quite a lot of messages.

How do I get access to physical memory from user space?  I want to write a
simple test problem to access the frame buffer directly on the LCD
controller.

See the archives.
