coreplex: CacheBlockOffsetBits was wrong!
...
This bug is ancient. I don't understand how it never mattered before.
Anyway, in processors with a custom CacheBlockBytes, this value is wrong!
The symptom is that TL1 components end up missing high address bits.
This causes, for example, a system to jump to 0 instead of RAM.
I don't understand how this very serious bug did not cause problems before.

rocketchip: must create bundles within Module scope
...
1. Bundles be created after base class Module constructor runs
2. Bundles must be created before Module(...) runs
Solution: pass a bundle constructor to the cake base class
Require the constructor to take a parameter so people don't use it by
accident; they should get a type error.
Consistently name all the cake arguments with an _io, _coreplex, _outer,
so that they don't shadow the base class variables you should be using.

Fix PutBlock after Release bug
...
There is logic in the broadcast hub to skip the outer acquire if there
is an outgoing release, since the data will be written out through the
release channel. However, this will cause an issue in the case of
PutBlock requests. If the tail beats of the PutBlock show up after the
outer release has already been sent, the data will be corrupted.
The fix is to make the outer release block if there are pending
inner PutBlock beats.

this an lead to 'data' changing while 'valid' is high. A violation. The
problem is that RegMapper is fundamentally DecoupledIO. So fix it with a
