yesterday... actually 3am this morning... i was able to put together the gram simulated PHY and track down what the hell is going on.

the firmware for gram had been written for 32 bit RV32 and had fundamental assumptions about writing to memory-mapped registers.

fortunately the microwatt team had written helper functions for memory-mapped IO that use stdcix and stwcix already.

after checking that at least the right DFI registers are written to under verilator a rebuild for VERSA_ECP5 is underway.
