[PATCH 0/3] Compile boards only when firmware is present

[Sascha Hauer <s.hauer@pengutronix.de>]

We have recently introduced ARM multi_*_defconfig files to compile
for multiple SoC families in a single config. Before these can
successfully be compiled a bunch of firmware files need to be present
in the source tree. This can be inconvenient for users as they have
to grab the firmware files from several sources before they can
compile these configs, even though they might be only interested
in a single board.

To solve this make the boards depending on a firmware file selectable
only when the firmware is actually present. With this the
multi_*_defconfigs can always be built. Boards with missing firmware
files will be skipped from compilation automatically.

The next step might be to introduce a Kconfig option (or use existing
COMPILE_TEST option) to provide dummy files for the missing firmware
files which could help for compile testing.
