Using MMIO device with Vanadis

1 - Detailed description of problem or enhancement

Hi All, I am working on getting the MMIO version balar to work with Vanadis. My previous solution was to add a router between CPU and the L1D cache to allow LD/ST towards MMIO to bypass the cache. This works great before I sync up with the newest devel branch, which introduces TLB to Vanadis.

My question now is can I still add the router between the CPU DTLB and L1D with the current Vanadis core? I did attempt this but failed since the TLB is not using standardInterface to connect to the cache. Or does a different solution exist?

2 - Describe how to reproduce

N/A

3 - What Operating system(s) and versions

Ubuntu 18.04
