c5838dd9b3 Fix narrow read/write behavior for AXI converters and fix L2 bugs
Until recently, we were assuming that the data channel in AXI was always
right-justified. However, for narrow writes, the data must actually be
aligned within the byte lanes. This commit changes some of the
converters in order to fix this issue.

There was a bug in the L2 cache in which a merged get request was
causing the tracker to read the old data from the data array,
overwriting the updated data acquired from outer memory. Changed it so
that pending_reads is no longer set if the data in the buffer is already
valid.

There was a bug in the PortedTileLinkCrossbar. The new GrantFromSrc and
FinishToDst types used client_id for routing to managers. This caused
bits to get cut off, which meant the Finish messages could not be routed
correctly. Changed to use manager_id instead.

b2eabf4a9f Add tracegen scripts inc. bugfix from @mwachs5
A step towards moving the tracegen scripts from rocket-chip to
groundtest.  I will raise an issue requesting that the scripts are now
removed from rocket-chip by someone with write access.

I have updated the README to account for the move.

This commit includes a bugfix from @mwachs5 (with slight mods by me)
relating to potential division by zero in toaxe.py.

7285f5e6bf Don't drive D$ kill/phys signals for SimpleHellaCacheIF

51e0870e23 Separate I$ and D$ interface signals that span clock cycles
For example, Decopuled[HellaCacheReq].bits.kill doesn't make sense,
since it doesn't come the same cycle as ready/valid.

6d3bba6cff Tweaks to README.md
Remove occurrences of ../scripts/ and instead state that it must be in
your PATH.  Also drop the content introducing the isit script as
tracegen+check.sh subsumes this.
