Could do some math; e.g. the offset is 768, first sector is 2048. So if
2048-768-(size-of-in-sectors u-boot.img) >> 0, it should be ok. Better
checking that done currently, at least.

But more sophisticated, of course, would be checking the actual layout
of the partition table... some targets (pine64+/pinebook) have offsets
that conflict with GPT partition tables, for example.

Hmmm...

Short of that, here's an updated u-boot 2019.04 patch that:

- Generates a u-boot-am335x-boneblack package with a slightly modified
  am335x_evm configuration removing extra device-trees; that *should* be
  small enough to fit with the common partition tables (but so far
  untested). It theoretically has about 80k of wiggle-room for
  u-boot.img to grow before it becomes a problem again.

- Better commented patch fixing mkimage to pass test-imagetools test
  suite. Patch was accepted in at least one of the maintainer trees
  upstream.

live well,

+Subject: [PATCH,v2] fdt: Fix mkimage list to try every header type
+Origin: https://patchwork.ozlabs.org/patch/1083495/
+
+Image type is not supplied to `mkimage -l`. For this reason, we cannot
+use imagetool_verify_print_header_by_type. Instead, this patch uses
+imagetool_verify_print_header to look through all header types to find
+one where image validation succeeds.
+
+This patch fixes failures in test/image/test-imagetools.sh
