From db36359f48ffa15ecfc9d5285d47c09bb95e8fa8 Mon Sep 17 00:00:00 2001 From: Jonas Gorski Date: Mon, 13 Jan 2014 12:13:15 +0000 Subject: brcm63xx: remove non runtime detect and refresh affinity patches Remove the non runtime detect code since its effectiveness is dubious and almost never used. Also update affinity patches to work on top of it.
