[Buildroot] [PATCH v2 1/2] configs: Add support for Toradex Colibri Vybrid Modules

[Thomas Petazzoni]

Hello,

Thanks for this new iteration, and sorry for the very slow response.
Are you still interested in getting this defconfig merged in Buildroot
upstream? If so, please see my comments below.

We need your Signed-off-by line here.

Please add here:

# Linux headers same as kernel, a 4.5 series
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_4_5=y

Of course 4.5 should be adjusted to match the kernel version you're
using. This is needed to make sure that the toolchain is built with
kernel headers that are at least as old as the kernel running on the
target.

Remove the -o ubifs.img, it is anyway overridden by the ubifs.mk build
logic in Buildroot. If you really want to rename the file, do so in a
post-image script.

I have some more comments on the second patch, which I'll do now.

Thanks!
