From 748e701b74f22d50dfb4d46ad5a8d0003c2c8b0f Mon Sep 17 00:00:00 2001 From: Thibaut VARENE Date: Fri, 10 Feb 2017 20:36:50 +0100 Subject: ar71xx: add preliminary kernel support for several RB SPI NOR devices The cAP 2nD, mAP 2nD and wAP 2nD apparently all share the same QCA953x/SPI-NOR platform. This patch adds preliminary kernel support based on init data used in Mikrotik's linux-3.3.5 kernel patch. Since this is totally experimental and untested, the necessary glue in base-files has not been added, the code is provided as a starting point in case somebody with that hardware wants to help getting it supported. The cAP lite (cAPL 2nD) should also be supported once it is determined whether or not it uses the same board identifier as the mAP lite. Code has been successfully built and has no side effect (no impact on already supported devices).
