- The actual bugfix for registered crossbar timings. · 2d2f5265
  Wesley W. Terpstra authored 13 years ago and Tomasz Wlostowski committed 13 years ago
```
This bug allowed a high priority master to seize control of a lower priority master if:
1. The low priority master had control for exactly one cycle
2. Combinatorial crossbar mode was off

... this made it possible to "steal the ACK" of another device and cause the bus to stall.

This commit will be followed by a few others which also tidy up the code a
bit in a way that would have made this bug more obvious to a reviewer.

```
When GSI replaced the lattice specific ram block with inferred memory, it became impossible to clear the register file as described by the two deleted lines. It is also unnecessary as the ram block starts zeroed.
