[Libre-soc-dev] test_mmu_dcache_pi.py working

[Luke Kenneth Casson Leighton]

tobias you'll be pleased to know the unit test you wrote worked, after
one tiny modification:
https://git.libre-soc.org/?p=soc.git;a=commitdiff;h=7f8c82e426e21c5700ccb342071fbf9e37b4c88e

all it needed was to always return something - zero is ok - in wb_get.
then it worked perfectly.

next thing i will do is try a LoadStore1 unit test.  this *should*
work straight away by copy
cut/pasting one of the existing PortInterface unit tests, except of
course use wb_get().
