2022-09-22virtualization/linux-yocto: For kernel metadata use git repository instead ↵Vasyl Vavrychuk1-13/+0
of local files. This will allow using branches for supporting multiple kernel versions more easily. Note, that BSP description root file virtio-aarch64-standard.scc has to be kept local withing a recipe. This is needed to add this scc file explicitly to SRC_URI to have AGL VIRTIO patches applied during kernel recipe build. As explained in [1, 2], Yocto kernel metadata is commonly used for two purposes: 1. To construct Yocto kernel git by committing patches listed in scc files. 2. To configure Yocto kernel during Yocto build. When scc file is not explicitly added to SRC_URI, then patch commands will be ignored during Yocto build because it is assumed that patches are already pre-applied during Yocto kernel git tree construction. But, there is not AGL Linux kernel tree, only a repository for AGL kernel metadata (this one). So, patches from this metadata repository have to be applied during kernel recipe build. On the other hand, to ignore patches from YP kernel metadata (which are already pre-applied), standard.scc is included with `nopatch` keyword.

It allows to use patch command to apply patches via scc file. As explained in [1,2], Yocto kernel metadata is commonly used for two purposes: 1. To construct Yocto kernel git by committing patches listed in scc files. 2. To configure Yocto kernel during Yocto build. When scc file is not explicitly added to SRC_URI, then patch commands will be ignored during Yocto build because it is assumed that patches are already pre-applied during Yocto kernel git tree construction. On the other hand, nopatch should be added to standard.scc because patches from it are actually pre-applied.
