Revert "Unsignify lengths and addresses in chip functions and structs"
- probe_timing was changed to unsigned although we use negative values for special cases - some code was not changed along hence did no longer compile: * dediprog's read and write functions * linux_spi's read and write functions - it introduced a number of new sign conversion warnings (http://paste.flashrom.org/view.php?id=832) To be safe this patch reverts all changes made in r1448, a corrected patch will follow later. Thanks to idwer for pointing out the problem first! Corresponding to flashrom svn r1450.
