+# resolve includes and any CONFIG options used. This produces dsdt.asl.tmp
+# which is pure ASL code. The Intel ASL (ACPI (Advanced Configuration and Power
+# Interface) Source Language compiler (iasl) then converts this ASL code into a
+# C file containing the hex data to build into U-Boot. This file is called
+# dsdt.hex (despite us setting the prefix to .../dsdt.asl.tmp) so must be
+# renamed to dsdt.c for consumption by the build system.
