I notice that the patch affects the size of the resulting U-Boot images.

Delta: +3896 BytesFor other boards it's only a few hundred bytes, but why do we see such big increase here?
In this case, these libraries contribute 3260 bytes in unused definitions:
In each case, a whole object file contains exactly the unused definitions, and could be excluded in the respective Makefile.
or just use -ffunction-sections/-fdata-sections/-Wl,--gc-sections and dont worry about it. which is what we do for the Blackfin port.
If you do worry, you can use the "--gc-sections" together with "--print-gc-sections" to actually find out what is unused[1].
