Board specific bbappend file

[Stefan Roese <stefan.roese@gmail.com>]

Dear List!

I'm trying to add a board specific *.bbappend file to a recipe. To add
board specific informations/settings to this recipe but without changing
the common (generic) recipe (*.bb) file. Something like this:

recipe:
linux-xyz_3.12.bb

board-specific append file:
linux-xyz-board-foo_3.12.bbappend

From the documentation I read:
"
Append files must have the same root names as their corresponding
recipes. For example, the append file someapp_1.5.1.bbappend must apply
to someapp_1.5.1.bb.
"

So it seems impossible to "encrypt" the board name into the bbappend
file name. Or am I missing something?

If not, is there another way to add such board-specific stuff to a
recipe without changing the generic recipe?

Thanks,
Stefan
