2015-12-26sim: mips: delete mmu stubs to move to common sim_{read,write}Mike Frysinger1-163/+102
The only unique thing about mip's sim_{read,write} helpers is the call to address_translation on the incoming address. When we look closer at that function though, we see it's just a stub that maps physical to virtual, and the cache/return values are hardcoded. If we delete this function, we can then collapse all the callers and drop the custom sim_{read,write} logic entirely. Some day we might want to add MMU support, but when we do, we'll want to have the common layers handle things so all targets benefit.
