[U-Boot] [PATCH 1/2] net: mv88e61xx: add configuration for RGMII delay

2018-06-25 Thread Chris Packham
Some hardware designs connect a CPU MAC directly to the RGMII interface of a mv88e61xx device. On such devices a delay on the RX/TX lines is required, this can either be achieved by adding extra length to the traces on the PCB or by implementing the delay in silicon. This is an implementation of
