That is because they are voluntarily overlapped. This looks like the
patch I recently did, which in essence does overlap BSS (which is not
used before relocation) and relocation tables (which are not used after
relocation) so that the FLASH and RAM footprint remain minimal.

This should not result in a linker message unless the .lds does not
follow the same structure (order and attributes of output sections) as,
for instance, the arm926ejs u-boot.lds.

Look up the u-boot.lds files. Are they shared?
