From a73154618283d7b8fd2107f6939834956b77b254 Mon Sep 17 00:00:00 2001 From: Nicolas Dechesne Date: Wed, 13 Sep 2017 21:38:20 +0200 Subject: kernel.bbclass: fix KERNEL_IMAGETYPE(S) for Image.gz KERNEL_IMAGETYPES lists all the kernel images that we want to build. in cb17b6c2a7 (kernel.bbclass: support kernel image type of vmlinux.gz), some logic was added to support vmlinux.gz which is not a target built by kernel makefiles (only vmlinux). It is clear that the goal of this logic is only to support vmlinux.gz and not others compressed format (such as Image.gz) which are valid target for kernel makefiles. For Image.gz we should rely on the kernel makefiles and not do the compression in kernel class. This patch updates the logic used to filter out non supported kernel target from KERNEL_IMAGETYPES, and make vmlinux.gz a 'special case', instead of *.gz. If more special cases are needed in the future, we could add them in a similar way. This patch should be a no-op for anyone using vmlinux or vmlinux.gz, and on top of that it is fixing the build for Image.gz which was not working until now.
