f255193841 Vastly simplified DMA Connect that does not buffer data at all.
This has not been tested yet, but it builds.

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.

fb259583dc Attempt to clear tag on exception path before forwarding.
This is likely to be bad for timing, but might just work at 25MHz.

37a7745f1a Fix a few errors in the previous commit, and importantly, make the
"push" from writeback just a write to the location that was meant to
push to, rather than the current head.

9d68d877d9 Move to much simpler design.
Just update the head in Decode, and write data from Execute.
A loop calling from the same place will at least find the correct
address.
Also, the bad fixup interaction is solved.

bbdcf6dde9 A more sophisticated RAS protection delay.
Saturate down, and also predict with old push value if there is more
than 6 cycles of delay.

064cd22114 Inteligently delay Decode (for up to 8 cycles) if we encounter a pop
while waiting for a push.
