Programmer specific functions are of absolutely no interest to any file except those dealing with programmer specific actions (special SPI commands and the generic core). The new header structure is as follows (and yes, improvements are possible): flashchips.h flash chip IDs chipdrivers.h chip-specific read/write/... functions flash.h common header for all stuff that doesn't fit elsewhere hwaccess.h hardware access functions programmer.h programmer specific functions coreboot_tables.h header from coreboot, internal programmer only spi.h SPI command definitions Corresponding to flashrom svn r1112.
