[isar-cip-core][PATCH v3 7/9] add linux 6.1 mainline kernel

Felix Moessbauer <felix.moessbauer@...> #10882 This patch adds the vanilla 6.1 linux kernel for testing and for boards which need a more recent kernel than what CIP can offer. The kernel can be selected from the menu, similar to the other kernels. As defconfig, we always use the kernels internal configuration, because there is no cip-kernel-config for that version yet. In addition, the squashfs knob is selected to support the swupdate pattern without any modifications.

As this squashfs=m default bit us now for many times (e.g. required distro kernels), I'm thinking about simply always adding the initramfs hook. In case squashfs is already enabled, a modprobe does not hurt anyways. Makes sense. Jan -- Siemens AG, Technology Competence Center Embedded Linux

By that, we somewhere have to flip the switch. If we will get the 6.1 cip-kernel-config rather soon, I vote for waiting. Otherwise I would just keep it as it currently is (dedicated file). You can accelerate the former by creating an MR on https://gitlab.com/cip-project/cip-kernel/cip-kernel-config. Jan -- Siemens AG, Technology Competence Center Embedded Linux
