5d5c072422
This patch is only the first step, but it hopefully will make working with the code and especially porting to new platforms easier. Subsequent patches should move #includes for the newly created files hwaccess.h and chipdrivers.h from flash.h to the files which need them. Programmers should live in a separate header file as well. Tested-by: Idwer Vollering <vidwer@gmail.com> Corresponding to flashrom svn r799.
