Hello Greg,

I've got two comments, which while not strictly addressing your issue, 
might be useful still.

- I was able to successfully boot multi-image files on powerpc some time
ago, but in a slightly different way: I had kernel, initrd and the blob
all in one file, and used just one argument to bootm, e.g.:

tftp 800000 /tftpboot/kernel+initrd+dtb.img
bootm 800000


- The above booting scenario does not work on recent U-Boot. I am
looking into this and I will try to report back in a few days.
Meanwhile you could try U-Boot as of commit
7049288fb1f16f1b317140226cdebd07bd416395 and see if it works for you.


HTH,
Bartlomiej
