在移植cc3351驱动至linux6.1内核中，使用buildroot工具时，发现注册cfg80211模块时，报错，信息如下
[ 56.140848] cfg80211: Loading compiled-in X.509 certificates for regulatory database
[ 56.195940] cfg80211: Loaded X.509 cert 'wens: 61c038651aabdcf94bd0ac7ff06c7248db18c600'

[ 56.211819] platform regulatory.0: Direct firmware load for regulatory.db failed with error -2
[ 56.220496] cfg80211: failed to load regulatory.db
提示需要配置
lib/firmware/regulatory.db
请问buildroot中 是否没有添加 TI cc3351相关固件信息？如果没有，我该如何处理？
