To further improve cleanup and maintenance usage, move the kernel version files to target/linux/generic directory. This permits to self contain any change to the specific generic directory instead of having to bload the include directory of periodic changes. In kernel-version.mk we now use GENERIC_PLATFORM_DIR provided by target.mk. To make this work, we need to move the inclusion of kernel-version.mk in target.mk right after GENERIC_PLATFORM_DIR is defined. This also comes to permit downstream project to provide a custom generic directory and specify the kernel version complete of the hash and the minor version without having to affect other feeds. In such case both generic and the target directory are provided as feeds and OpenWrt reference these specific one instead of the generic one. For downstream it's still suggested and preferable to all match the shipped generic kernel minor version but this change permits to at least enforce good practice instead of having to bloat OpenWrt include file of all kind of downstream changes (making porting to OpenWrt mainline even more difficult) Link: https://github.com/openwrt/openwrt/pull/18537 Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
