[ptxdist] [PATCH v4 4/4] barebox: add integration of firmware blobs

[Michael Riesch <michael.riesch@wolfvision.net>]

In some cases barebox requires firmware blobs, which may be
provided in binary form by the vendor or compiled in a
preceding step. Add the possibility to specify files (in
separate rule files) which are injected in the barebox source
directory during preparation.
