[libre-riscv-dev] memory interface diagram woes

[Luke Kenneth Casson Leighton]

aw god this isn't funny any more! (actually... it is).  there's a
store-with-update that's separate from load-with-update.  so there are
*four* combinations:

* LD Mode will activate Issue, GoRead1, GoAddr then GoWrite1
* LD-UPDATE Mode will *additionally* activate GoWrite2.
* ST Mode will activate Issue, GoRead1, GoRead2, GoAddr then GoStore.
  ST-UPDATE Mode will *additionally* activate GoWrite2.

i might be able to recover the current diagram without rewriting it.
