All programmer access function prototypes except init have been made static and moved to the respective file. A few internal functions in flash chip drivers had chipaddr parameters which are no longer needed. The lines touched by flashctx changes have been adjusted to 80 columns except in header files. Corresponding to flashrom svn r1474. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Michael Karcher <flashrom@mkarcher.dialup.fu-berlin.de>
