- Document new 'satasii' programmer in -L output and manpage. - Drop PCI_IO_BASE_ADDRESS, pci.h has such #defines already. - Beautify flashrom output and make it more consistent. - Same for the 'make' output (reordered some $CC parameters). Build-tested on i386, shouldn't break any builds, I think. - Some variable renaming and other cosmetic fixes. Corresponding to flashrom svn r529.
