* Define a CPWAIT macro as described in the i80200 manual and use it, rather than replicating the code in a few places. * The i80200 manual notes that the line-allocate operation used to do global D$ clean does not actually perform a load/fill request from external memory, and thus does not actually place valid data in the cache lines allocated. Require that machine-dependent code allocate an appropriately-sized chunk of unmapped VA space for the global clean operation in order to avoid unpredictable results. * The i80200 manual notes that the VA range for the Mini-Data global clean (which *must* be mapped to physical memory) must be reserved exclusively for cleaning the Mini-Data cache. Require that machine- dependent code allocate an appropriately-sized chunk of memory for this purpose.
