598ac6574e Added working Konata support 
Konata: change M to F3

Added konata support to ALU pipeline

Added KONATA support to Fpu pipeline

Added KONATA support to Mem pipeline

Finished v1 of KONATA support

Added improvements to catch fragments in Konata

Kill fragments that have been merged

Fixed order of konata logs

Added commit stage output

Ensured that only the Commit stage can retire instructions in konata

Fixed printing commit stage log for Cap instructions

Changed Kanata to include the cycle counter for each line in the log file; please note that this requires post processing

Added reservation station support for Konata

449070e347 Copied over preliminary Konata support from 89b0c37a7b 
The referenced commit did not merge well with our code base. Therefore, I copied over the changes manually. These changes do
not constitute a working Konata support for Toooba. In this commit, I commented out some things that did not compile, which will be fixed in future

opportunity to flush the buffered translations.

b733e05a86 A scheduling experiment to try to get doRegReadMem and doExeMem 
executing in the same clock cycle.  It doesn't seem to work (yet).

32d094082b Some tracing for performance in the memory pipeline. 
Also, add some ports to registers in DTLB to potentially allow
single-cycle lookup.

2d05514b66 An experimental simplification of the SplitLSQ, which I think works 
because the Memory pipeline only ever reads the getIssueLd interface in
the same rule that it calls issueLd.

c8b0e12f79 Remove traps for CBuildCap 
This will be very expensive in terms of area and possibly timing.
Ideally this instruction would be multi-cycle or optimised to reduce the overhead.

ddf4afaf71 Changes to build with a 512-bit main data bus (with all other busses 
still 64-bits).
Also, the top-level SoC_Top exposes a 64-bit bus still, so hopefully the
GFE configuration is unchanged.
This passes the isa_tests.

04ba0cb7ab Prefer tag clearing to trapping when manipulating a sealed capability 
This causes the behaviour of CCSeal and CSeal to diverge in non-trapping cases,
meaning an extra case is added to CapModify.
