2018-07-05kernel_wireless_regdb: Add class for embedding regulatory data into older kernelKrzysztof Kozlowski
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.
