This is related to the spi split patch as discussed in: http://www.flashrom.org/pipermail/flashrom/2010-February/thread.html#2364 the old commit (r914) log notes: "Some of the spi programmer drivers required chipdrivers.h, needs fixing later: it87spi.c ichspi.c sb600spi.c wbsio_spi.c buspirate_spi.c ft2232spi.c bitbang_spi.c dediprog.c" there still remain a few cases where chipdrivers.h is needed: dediprog.c (spi_read_chunked and spi_write_chunked) it87spi.c (due to spi_write_enable and spi_read_status_register) wbsio_spi.c (spi_programmer registration only) besides that, there are also non-spi files that do not need it. also, add flash.h to chipdrivers.h because it uses some types of it and remove flashchips.h from print.c Corresponding to flashrom svn r1414.
