 # Fixup inclusion of libfdt headers, which can fail in older u-boot versions
 # when libfdt-devel is installed system-wide.
 # The core change is equivalent to upstream commit
 # e0d20dc1521e74b82dbd69be53a048847798a90a (first in v2018.03). However, the fixup
 # is complicated by the fact that the underlying u-boot code changed multiple
 # times in history:
 # - The directory scripts/dtc/libfdt only exists since upstream commit
 #   c0e032e0090d6541549b19cc47e06ccd1f302893 (first in v2017.11). For earlier
 #   versions, create a dummy scripts/dtc/libfdt directory with symlinks for the
 #   fdt-related files. This allows to use the same -I<path> option for both
 #   cases.
 # - The variable 'srctree' used to be called 'SRCTREE' before upstream commit
 #   01286329b27b27eaeda045b469d41b1d9fce545a (first in v2014.04).
 # - The original location for libfdt, 'lib/libfdt/', used to be simply
 #   'libfdt' before upstream commit 0de71d507157c4bd4fddcd3a419140d2b986eed2
 #   (first in v2010.06). Make the 'lib' part optional in the substitution to
 #   handle this.

	# versions, create a dummy scripts/dtc/libfdt directory with symlinks for the
	# fdt-related files. This allows to use the same -I<path> option for both
	# cases.
	# - The variable 'srctree' used to be called 'SRCTREE' before upstream commit
	# 01286329b27b27eaeda045b469d41b1d9fce545a (first in v2014.04).
	# - The original location for libfdt, 'lib/libfdt/', used to be simply
	# 'libfdt' before upstream commit 0de71d507157c4bd4fddcd3a419140d2b986eed2
