@pgkeller Any concerns with adding a uint16_t eth_chan_to_noc_xy[NUM_NOCS][NUM_ETH_CHANS] to the generated_bank_to_noc_coord_mapping.h? I thought about adding a separate header file, but this seemed easier. It would make sense to rename the mapping file to maybe generated_noc_xy_mapping.h?

Aside, I think we should switch (((2 << NOC_ADDR_NODE_ID_BITS) | 8) << NOC_COORD_REG_OFFSET), to just NOC_XY_ENDCODING(2, 8) for all the generated maps.

Closing, as there will be new infra to load the generated noc_xy_encoding maps.
