commit e91d08f811cef625f1064ad452fbe21c79341279 Author: yangao1 <[email protected]> AuthorDate: Mon Dec 30 20:28:14 2024 +0800 drivers/rpmsg: add rpmsg_initialize() Add a one-time initialization hook for the rpmsg framework, called from drivers_initialize() when CONFIG_RPMSG is enabled, so that framework wide facilities such as the trace and procfs support added next have a place to set themselves up before any rpmsg device registers.
