From 8603b7643b9025bf88dd55165ec808c4cea144e3 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Thu, 5 Jul 2018 20:58:12 +0200 Subject: kernel_wireless_regdb: Add class for embedding regulatory data into older kernel Linux kernels before v4.15, allowed to be compiled with static regulatory database if it was put under net/wireless/db.txt. Add kernel_wireless_regdb class which allows in such cases to embed the wireless regulatory database directly in the Linux kernel during build process. Usage: 1. The class should be inherited by kernel recipe (e.g. in linux-yocto_%.bbappend). 2. For Linux kernels up to v4.14, build kernel with CONFIG_EXPERT and CONFIG_CFG80211_INTERNAL_REGDB.
