Change subject: arch-arm: Implement multi-level TLB
......................................................................
arch-arm: Implement multi-level TLB
- The TLB levels are connected through ports with the table walker as the
last level. Several options to configure each TLB have been defined:
* Access latency
* Associativity
* Replacement policies
* Store partial translations
- The table walker can be configured to allow more than 1 page walk at a
time
- The stage 2 TLB hierarchy is by default following the same structure of
the
defined stage 1 hierarchy
