From ecdce239a54b7a4c4aa760a659c13642e1817326 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Sun, 23 Aug 2015 09:35:56 +0000 Subject: brcm63xx: ensure dummy byte is set for mapped spi flash with fast read Some CFEs seem to misconfigure the mapped memory flash access with fast read but without a dummy byte, causing all accesses to be prefixed with 0xff. This of course breaks reading out the nvram, so do not just move back to single i/o accessors, but also ensure that the dummy byte is correctly set.
