Which clock is the reference clock for the HPS Ethernet MDC clock?

Description

The correct reference clock for the HPS Ethernet clock is l4_mp_clk.

The V HPS Address Map, emac->gmacgrp->GMII_Address->cr incorrectly states the CSR clock range selection determines the frequency of the MDC clock according to l3_sp_clk frequency.

Resolution

This problem is resolved starting with release 15.1 of the HPS Address Map.
