Massive update containing several months of changes from the now-defunct private chip repo. * Adds support for a L2 cache with directory bits for tracking L1 coherence (DefaultL2Config), and new metadata-based coherence API. * Additional tests. * New virtual memory implementation, priviliged architecture (1.7), custom CSRs, FDivSqrt unit * Updated TileLink protocol, NASTI protocol SHIMs. * Lays groundwork for multiple top-level memory channels, superscalar fetch. * Bump all submodules. 2015-06-26 08:17:35 +02:00			`SHELL := /bin/bash`
