From mboxrd@z Thu Jan 1 00:00:00 1970 From: zajec5@gmail.com (=?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?=) Date: Sun, 14 Dec 2014 15:13:07 +0100 Subject: [PATCH] ARM: display machine model in cpuinfo Message-ID: <1418566387-16468-1-git-send-email-zajec5@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This may be useful to display hardware model in the /proc/cpuinfo. It definitely helps to identify the device and there are some archs already doing that (arm64, m32r, mips). Use the model from DT and add it to the cpuinfo. Signed-off-by: Rafa?
