No problem, I hope you had a good time.

The last two lines are the addresses of the ROM modules that are printed
when the system starts (I assume this is where u-boot uncompressed the
content to, and that core prints the addresses while parsing the elf).

If my assumptions, that u-boot decompressed uImage to 0x10001000 and up,
and that the list of modules printed at startup is the uncompressed
location and size of the ROM modules, then you are right, the
possibility for an overlap is relatively high.

As I currently have a working setup, and know what to keep an eye on,
you may regard this as solved for the moment. I will keep in mind, to
check for overlap of memory regions in the future, when booting the
system fails.

Best regards
