In the commit message, let us stick to just what the kernel folks need
to know. Specifics of bootloader etc can belong to the diffstat -
unless the patch has direct relationship to the bootloader in some form
and we need to refer to that details in git log in the kernel (the
diffstat and discussion information is already on public-inbox if anyone
wants to do "deep research" :P ).

Device Tree is about describing hardware. Let us keep it to that.
