From c8e8ff1c9fbf699d04e2dc9e01d3349878ef7883 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Mon, 30 Jul 2018 08:36:26 +0200 Subject: brcm47xx: rework model detection MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On brcm47xx boards, the model ID is the combination of the "boardtype" nvram variable and an optional supplemental "boardnum" variable while the human readable model name is usually exposed in the "machine" field of the /proc/cpuinfo file. Move the extraction of the board nvram variables and model name string into the 01_sysinfo file and rework the 01_detect board configuration script to solely use the prepared sysinfo values without performing own detection logic. As a consequence, we can drop the ucidef_set_board_id() and ucidef_set_model_name() invocations in favor to the generic behaviour which copies the /tmp/sysinfo/{board_name,model} values into the board.json "id" and "name" fields respectively. Since "01_detect" only contains network configuration logic after this change, move it to "01_network" and rename the contained "detect_by_xxx" functions to "configure_by_xxx" instead, to avoid potential confusion.
