> * Assigning offsets as we assign sections to output sections
Please keep in mind that output section size and symbol values depend on
output section VA,
because you can have the following kind of expression within section
. = ALIGN(0x8);
I will wait for Rui, just in case he wants something to be fixed before
landing this patch.

> I will probably send the second patch for review once this one is in.
