[libre-riscv-dev] [Bug 216] LOAD STORE buffer needed

--- Comment #27 from Luke Kenneth Casson Leighton <lkcl at lkcl.net> ---
i may need to implement a very basic (working) of the API in
http://bugs.libre-riscv.org/show_bug.cgi?id=216#c26
effectively a thin "wrapper" around nmigen Memory rdport and wrport.

it's not quite a perfect match for nmigen rdport/wrport as the
address phase needs latching in, separately from how r/w data is handled.

i'll make sure that the (decoded) opcode is passed over because it
contains crucial information (not just ld/st-length).
