0baa1c9a45 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.

bbabcf67ff coreplex: width adapter should happen as part of coherence manager 
In the future we will want the L2 to be wider on the backside so that
we can take advantage of fat DDR controllers (256bits/beat).

5f3fb64ef0 Per ABI, only x1 and x5 should be treated as function returns 
We were doing so for x3 and x7, as well, which could reduce performance
for compilers that happen to perform indirect jumps via t2 (x7).
