[libre-riscv-dev] Reuse of load_store_unit.sv from the ariane soc

[Tobias Platen]

Three weeks ago I have worked on the ariane mmu module. Since the only 
module which uses the mmu is load_store_unit.sv, I will now try to 
convert that to nmigen using sv2nmigen. So my next task will be writing 
bug fixes for sv2nmigen.
