Author: hailfinger Date: 2010-01-06 11:21:00 +0100 (Wed, 06 Jan 2010) New Revision: 829
Added: trunk/programmer.c Modified: trunk/Makefile trunk/flash.h trunk/internal.c Log: Some programmers (most notably FT2232SPI) use fallback_* and noop_*, but those functions lived inside internal.c and were unavailable if no PCI-based programmers were compiled in. Move those functions to the new file programmer.c. Thanks to Patrick Georgi for finding this.
