annotate target-utils/libc/memcpy.S @ 720:b73c21a2148f

reorg: smallconv.c moved from ffstools/cal2text to librftab This module contains write_afcdac_ascii() and write_stdmap_ascii() functions; the plan is to make them available to other programs, particularly the upcoming addition of RF table dump to tiffs.
