[PATCH] kbuild: Add DTB_FILES variable for dtbs_check

[PATCH] kbuild: Add DTB_FILES variable for dtbs_check

[Nícolas F. R. A. Prado]

Currently running dtbs_check compiles and runs the DT checker on all
enabled devicetrees against all dt-bindings. This can take a long time,
and is an unnecessary burden when just validating a new devicetree or
changes in an existing one, with the dt-bindings unchanged.

Similarly to DT_SCHEMA_FILES for dt_binding_check, add a DTB_FILES
variable that can be passed to the dtbs_check make command to restrict
which devicetrees are validated.

make dtbs_check DTB_FILES='arch/arm64/boot/dts/mediatek/mt8192-asurada-spherion-r0.dtb arch/arm64/boot/dts/mediatek/mt8192-asurada-hayato-r1.dtb'

Hi,

I have just learned that it is already possible to achieve the same thing by
passing the dtbs explicitly to make and enabling the DTBS_CHECK flag like so:

make CHECK_DTBS=y mediatek/mt8192-asurada-spherion-r0.dtb

This flag isn't documented anywhere outside the Makefile however. So I'll send a
patch documenting it shortly, and this commit can be ignored.

Thanks,
Nícolas
