binman: Node '/fit at 0x380000/images/u-boot': Offset 0x0 (0) size 0xb8870
(755824) is outside the section '/fit at 0x380000' starting at 0x0 (0) of
size 0x400 (1024)

And for the second call:

binman: Node '/fit at 0x380000': Replacing sections is not implemented yet

We tried fixing but eventually had to give up. binman is not easy to
understand in these corners.
