PATCH v3 1/1 linux: Add CIP SLTS easy selection option

Hello,

Quoted 4 lines · Angelo Compagnucci

This patch adds an easy way to select the CIP project SLTS kernel within the kernel menu.

Signed-off-by Angelo Compagnucci <[email protected]>

I've applied after doing a few tweaks, see below.

I've completely dropped this option. Indeed, it is already possible without your patch to select a custom Git repository to download the kernel. So having yet another option to do that is useless. If you want to use a custom CIP repository, just use the existing BR2_LINUX_KERNEL_CUSTOM_GIT option.

Since this help text was useful, I've moved it under the BR2_LINUX_KERNEL_LATEST_CIP_VERSION option.

This prompt was too long and didn't fit in the menuconfig window. So I've removed the "(Super Long Term Support)" part of it, which is anyway explained in the help text.

Applied with those two changes. Thanks!
