Author: hailfinger Date: Thu Nov 10 00:40:00 2011 New Revision: 1463 URL: http://flashrom.org/trac/flashrom/changeset/1463
Log: Register Parallel/LPC/FWH programmers the same way SPI programmers are registered.
All programmers are now calling programmer registration functions and direct manipulations of buses_supported are not needed/possible anymore.
Note: Programmers without parallel/LPC/FWH chip support should not call register_par_programmer().
Additional fixes: Set max_rom_decode.parallel for drkaiser. Remove abuse of programmer_map_flash_region in it85spi. Annotate several FIXMEs in it85spi.
