I've since read up in the datasheet, I was close, it's "image vector
table".  I've been trying to hexdump a "known good" image and my broken
ones to figure out what's going on.

I can make some sense of the SD image header, but yet to fully figure
out the bootstream format itself.  Searching for more information on the
issue simply reveals copies of my earlier email to this list.

I've now tried numerous other toolchain version combinations, including
building it on a Debian chroot.  I don't seem to be able to get SPL
debugging going -- even though I've #define'd DEBUG, and
CONFIG_SPL_SERIAL_SUPPORT.

I figure if I had the wrong pins configured, I wouldn't even see the
error code I've been getting, so clearly that works.

I've been trying to debug this for days now and it's driving me insane.

The code previously worked.  I've also tried building images for the
mx28evk, which is a very similar board to the one I'm using, and I get
the same result.

I ask again: Is there somewhere else I should be looking for the cause
of the above issue?
