I wanted to try using tools/fit_check_sign as a quick way to bisect this, unfortunately the v2020.10-rc4 version (also) says that the kernel image is correctly signed.

Does anyone have a crystal ball that says what might have changed to cause this? The board in question is based on mpc8309, i.e. big-endian powerpc.

I had a hunch that is was an endianness issue since fit_check_sign (run on the little-endian build host) reported success, and indeed it is.
