Use physmap_of to access RAMs as mtd and add documenation for it. This approach is a lot less intrusive as adding an of-wrapper around plat-ram.c. As most extensions of plat-ram.c (e.g. custom map-functions) can't be mapped to the device tree anyhow, extending physmap_of seems to be the cleanest approach.
The patch works nicely on a custom (roughly Icecube) based 5200B board, with a Renesas static ram, no partitions and a jffs2 file system on it. I had to add some more tweaks to physmap_of.c as to work around the 5200's limitations accessing chips in 16-bit mode through the local bus, which is a lot easier and cleaner with this patch than with the old one (of 05 June 09).
