^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  37) Each DTx is processed by the dtc compiler to produce a sorted dts source
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  38) file.  If DTx is a dts source file then it is pre-processed in the same
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  39) manner as done for the compile of the dts source file in the Linux kernel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  40) build system ('#include' and '/include/' directives are processed).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  41) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  42) If two DTx are provided, the resulting dts source files are diffed.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  43) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  44) If DTx is a directory, it is treated as a DT subtree, such as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  45)   /proc/device-tree.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  46) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  47) If DTx contains the binary blob magic value in the first four bytes,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  48)   it is treated as a binary blob (aka .dtb or FDT).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  49) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  50) Otherwise DTx is treated as a dts source file (aka .dts).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  51) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  52)    If this script is not run from the root of the linux source tree,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  53)    and DTx utilizes '#include' or '/include/' then the path of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  54)    linux source tree can be provided by '-s SRCTREE' or '-S' so that
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  55)    include paths will be set properly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  56) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  57)    The shell variable \${ARCH} must provide the architecture containing
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  58)    the dts source file for include paths to be set properly for '#include'
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  59)    or '/include/' to be processed.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  60) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  61)    If DTx_1 and DTx_2 are in different architectures, then this script
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  62)    may not work since \${ARCH} is part of the include path.  The following
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  63)    workaround can be used:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  64) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  65)       `basename $0` ARCH=arch_of_dtx_1 DTx_1 >tmp_dtx_1.dts
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  66)       `basename $0` ARCH=arch_of_dtx_2 DTx_2 >tmp_dtx_2.dts
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  67)       `basename $0` tmp_dtx_1.dts tmp_dtx_2.dts
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  68)       rm tmp_dtx_1.dts tmp_dtx_2.dts
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  69) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  70)    If DTx_1 and DTx_2 are in different directories, then this script will
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  71)    add the path of DTx_1 and DTx_2 to the include paths.  If DTx_2 includes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  72)    a local file that exists in both the path of DTx_1 and DTx_2 then the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  73)    file in the path of DTx_1 will incorrectly be included.  Possible
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  74)    workaround:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  75) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  76)       `basename $0` DTx_1 >tmp_dtx_1.dts
