From 5d53baf3f5b3e711fd809d9e0b39b29be994ba9c Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Fri, 25 Jun 2021 07:53:54 +0100 Subject: hw/mips/jazz: move PROM and checksum calculation from dp8393x device to board MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is in preparation for each board to have its own separate bit storage format and checksum for storing the MAC address.
