It was nice if it was set. But if you simply grep in this poathc, they
are not. Just changelog was touched.
But let's see what we can do to improve. I have merged patches up to 14
(without NAND support). I will push them to the server and they are part
of my next PR.
As I propose, I could fix this myself in this patch if you agree - or
then please post the rest of patches, but after checking the board can
be built.
Thanks !
