Ok, thanks for the help.
Now do I actually need to have the memory mapped in kernel space through
ioremap(), in order to have the memory mapped into user space through
remap_pfn_range()? It seems that remap_pfn_range() only requires a
physical address, not a virtual one.
If this is true then I really don't need to map this in kernel space at
all and only in user space, since it will only be manipulated in user
space.
Thanks,
Jon

I wasn't completely honest. It is one bar that has 512 MB, however it is

Is there still no chance?
128 MB is still definitely on the heavy side. Try 64 MB and you might
be able to get away with it.
