Subject: [PATCH] kbuild: Allow DTB overlays to built from .dtso named source
|
|
files
|
|
|
|
Currently DTB Overlays (.dtbo) are build from source files with the same
|
|
extension (.dts) as the base DTs (.dtb). This may become confusing and
|
|
even lead to wrong results. For example, a composite DTB (created from a
|
|
base DTB and a set of overlays) might have the same name as one of the
|
|
overlays that create it.
|
|
|
|
Different files should be generated from differently named sources.
|
|
.dtb <-> .dts
|
|
.dtbo <-> .dtso
|
|
|
|
We do not remove the ability to compile DTBO files from .dts files here,
|
|
only add a new rule allowing the .dtso file name. The current .dts named
|
|
overlays can be renamed with time. After all have been renamed we can
|
|
remove the other rule.
