[Qemu-devel] Ram allocation changes

[Paul Brook]

After my recent set of changes, qemu supports dynamic allocations of guest 
ram. Previously all guest ram had to be preallocated before device/board 
initialization.  This provides most of the infrastructure necessary for 
memory hotplug, and is a prerequisite for machine config files. There should 
be no user visible changes.

I've tested as many targets as I can. If your favourite target dies with "Bad 
ram offset" then the most likely cause is that the board needs to allocate 
its ram with qemu_ram_alloc, rather than blindly assuming it exists.
