From a16f48823928b6bfe1e2426b17af1ec325958595 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 1 Dec 2021 09:02:44 -0700 Subject: [PATCH] acpi: Allow include files within the board directory Some .asl files include others using the iasl 'include' directive. This needs to be able to find the files referenced. For an out-of-tree build the source directory is not the current directory. Moreover, U-Boot preprocesses the input file and puts the result in the output directory. So iasl does not know where the real source file came from. Add a -I option to produce the correct behaviour. We could add an option to not preprocess the .asl source, but for now that seems unnecessary.
