From 0b7a9688ce49c60a18575b925138b100f4e8e078 Mon Sep 17 00:00:00 2001 From: "Daniel F. Dickinson" Date: Sun, 29 Jul 2018 07:40:01 -0400 Subject: [PATCH] ar71xx: cr3000: cleanup board definition 1) Add comments so it's clear why we did things; this may prevent someone (e.g. me) from sinking time into fixing things that aren't broken and/or were done for reason. 2) Drop mdio 0 probe/register; we don't use ag1xx mdio bus 0. 3) Cosmetic reording of some code (tested) that makes the defintion more clear.
