From mboxrd@z Thu Jan 1 00:00:00 1970 From: sbranden@broadcom.com (Scott Branden) Date: Fri, 18 Apr 2014 10:13:20 -0700 Subject: [PATCH V2] ARM: mach-bcm: add ARM_ERRATA_775420 Message-ID: <1397841200-14061-1-git-send-email-sbranden@broadcom.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org ARM_ERRATA_775420 needs to be enabled. A data cache maintenance operation which aborts, followed by an ISB, without any DSB in-between, might lead to deadlock. Affects: bug present in Cortex-A9 r3p0 and earlier. Fixed in r4p0. Cortex-A9 r3p0 is used in a multitude of Broadcom parts including the bcm21664, bcm281xx, 5301x families of devices.
