[PATCH 0/3] RFC: add fdt_add_pubkey tool

[Rasmus Villemoes]

In order to reduce the coupling between building the kernel and
U-Boot, I'd like a tool that can add a public key to U-Boot's dtb
without simultaneously signing a FIT image. That tool doesn't seem to
exist, so I stole the necessary pieces from mkimage et al and put it
in a single .c file.

I'm still working on the details of my proposed "require just k out
these n required keys" and how it should be implemented, but it will
probably involve teaching this tool a bunch of new options. These
patches are not necessarily ready for inclusion (unless someone else
finds fdt_add_pubkey useful as is), but I thought I might as well send
it out for early comments.

Rasmus Villemoes (3):
  test_vboot.py: remove extraneous -k option to fit_check_sign
  tools: add fdt_add_pubkey
  test_vboot.py: include test of fdt_add_pubkey tool
