From 2c05932416e5f6b421f79a3250d88ffe4ce495c2 Mon Sep 17 00:00:00 2001 From: Vasyl Vavrychuk Date: Tue, 1 Nov 2022 22:04:36 +0100 Subject: virtualization: Add virtio-can driver as external module. This driver should conform RFC spec draft v2 [1]. This driver is based on RFC version [2]. Imported from internal OpenSynergy's revision: 3918336a7caab95a72442c33945a193ca893d5e8 Supply build file `Kbuild` and do not supply makefile [3] since external kernel module could be built without it. On the other hand, module BitBake class relies on wrapper makefile presence, therefore `MAKE_TARGETS` and `MODULES_INSTALL_TARGET` had to be set to specify arguments per [3]. Add driver as an external module to avoid unnecessary kernel rebuild and simplify future updates.
