7a1937242a coreplex: provide correct bus-width for ITIM blockers 2017-11-18 14:32:37 -08:00

tile: put a BasicBusBlocker inside RocketTile (#1115) 
...instead of on the master side of the system bus.

People inheriting from HasTileMasterPort might need to add
`masterNode := tileBus.node` to their Tile child class.

Fix stateless caching (#1084) 
* tilelink: ToAXI4 should format it's error message

* WithStatelessBridge: mark the memory bus incoherent and cacheable

... and hope that the user doesn't put more than one master down.

8b58327fa4 axi4: conversion from TL does not need beatBytes (#1051) 
We used to pack the addr_lo into user bits. We don't do that anymore.
There is thus no need to waste those bits, nor to pass that arg.
