From 44127b771d9c31dcb5ab90d9093a4d48877738bc Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 19 May 2014 13:05:59 -0700 Subject: bus: add Broadcom GISB bus arbiter timeout/error handler This patch adds support for the Broadcom GISB arbiter bus timeout/error handler. GISB is a proprietary bus used by Broadcom Set Top Box System-on-a-chip devices (BCM7xxx) which allows multiple masters and clients to be interfaced with each other. The bus arbiter offers support for generating two interrupts towards the host CPU, thus allowing us to "catch" clock gated masters, or masters being volontarily blocked for powersaving purposes, or do general system troubleshooting. We also register a hook with the ARM fault exception handling to allow printing a more informative message than "imprecise external abort at 0x00000000" for instance.
