From 2f9a0bec659700554744338bf780841f641cec40 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Thu, 27 Apr 2017 14:33:05 +0200 Subject: [PATCH] arm64: Print DT machine model in setup_machine_fdt() On arm32, the machine model specified in the device tree is printed during boot-up, courtesy of of_flat_dt_match_machine(). On arm64, of_flat_dt_match_machine() is not called, and the machine model information is not available from the kernel log. Print the machine model to make it easier to derive the machine model from an arbitrary kernel boot log.
