Application build systems can query the tool using the RTEMS_MKIMAGE package
configuration varible, for example:
pkg-config --variable=RTEMS_MKIMAGE
${prefix}/lib/pkgconfig/${ARCH}-${BSP_NAME}.pc
Nice. This is my preferred way of handling this.
If the BSP does not provide a tool, then the variable RTEMS_MKIMAGE is set to
"false".
So the process has to be a single command?
Yes, a single command which is written in Python. For the U-Boot image it
converts the ELF file to binary, then to a gz file, then to the U-Boot image.
I see it is in a YAML spec file. Sorry that is a no from me. See below.

We should not be in the habit of serializing source code inside a data
file without very good reasons to do so. This feels wrong.
I don't see the issue here. The variable substitution in the build
specification items is not as obscure as with m4.
If script generation needs to be done, it should be implemented in
Python with input from the yml spec item as necessary to fill out a
templated script with variables to customize for the BSP, and with
appropriate injection of comments etc to allow traceability backward
to the original source data and source program that generated the
script.
I think this is exactly the approach of the patch set. The Python script
which fills out the templated script with variables to customize for the
BSP is the wscript. You can of course also put comments into the
generated script. If you use the
if __name__ == "__main__":
approach, you could even provide an executable script and a module.
