From 76957cb3d621bf664311908e5962e151c633c285 Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Sat, 1 Mar 2008 12:11:40 +0100 Subject: ppc4xx: EMAC: Fix 405EZ fifo size setup in EMAC_MR1 The 405EZ only supports 512 bytes of rx-/tx-fifo EMAC sizes. But currently 4k/2k is configured. This patch fixes this issue. Thanks to Thomas Kindler for pointing this out.
