Change the configuration option to move this somewhere
else, outside of the wired mapping.
As I said in the last message, these lower end processors
are very resource challenged, and we need to clever
about the memory mapping and use of the TLBs. This
isn't a place to be creating fancy memory maps and
algorithms to manage them. Use maximum mappings
whenever possible, configure the memory controller
to pack as much stuff into this single TLB mapping
as possible. Something configurable like this memory
pool should not be a reason to give up these performance
enhancements.
Thanks.
