Nak -- what we want to overlay is .bss on one hand, and .rel.dyn *plus* .dynsym on the other hand; OVERLAY { ... } does not allow this.
[sp] From the earlier discussion, I inferred the overlay was supposed to be .rel.dyn and .bss.
That's because I avoid saying " .rel.dyn plus .dynsym" and just go for short ".rel.dyn" instead. Sorry for that.
Let me get the ".rel.dyn + .dynsym" overlay with ".bss".
If it works across compiler versions would that be okay?
Getting ".rel.dyn + .dynsym" overlay with ".bss" is exactly what the current linker file does, by emitting .rel.dyn, then .dynsym, then overlaying .bss back at the start of .rel.dyn. Look up a readelf -a of ./u-boot and see where each section starts and ends.
If you find another way to do this overlay yet end up producing a different binary, I'll be interested in the result, but I honestly don't think you will find any.
