From mboxrd@z Thu Jan 1 00:00:00 1970 From: sudeep.holla@arm.com (Sudeep Holla) Date: Tue, 18 Apr 2017 18:57:59 +0100 Subject: [PATCH 2/2] arm64: dts: juno: add information about L1 and L2 caches In-Reply-To: <1492538279-16405-1-git-send-email-sudeep.holla@arm.com> References: <1492538279-16405-1-git-send-email-sudeep.holla@arm.com> Message-ID: <1492538279-16405-2-git-send-email-sudeep.holla@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Commit a8d4636f96ad ("arm64: cacheinfo: Remove CCSIDR-based cache information probing") removed mechanism to extract cache information based on CCSIDR register as the architecture explicitly states no inference about the actual sizes of caches based on CCSIDR registers. Commit 9a802431c527 ("arm64: cacheinfo: add support to override cache levels via device tree") had already provided options to override cache information from the device tree. This patch adds the information about L1 and L2 caches on all variants of Juno platform.
