Comment (by Frank Kuehndel):

 The code is not dead. Chris Johns wrote on the mailing list:

 > With this command I know users on Zynq platforms that use FDT to map PL
 logic to drivers. The command is very much in use and is used as a PS to
 PL testing method. (Reference:
 [https://lists.rtems.org/pipermail/devel/2020-October/062802.html Email])

 In this case, I suggest the same as Chris did earlier:

 * Add it again to the shell.
 * Add it to the shell documentation.
 * Add a test for it. A simple smoke unit-test which loads an fdt (blob)
 and invokes the most important functions in file cpukit/libmisc/rtems-fdt
 /rtems-fdt.c would be great.
