From ad3cc55e139b2e239325815464fe5f7d828aa794 Mon Sep 17 00:00:00 2001 From: Carl-Daniel Hailfinger Date: Sat, 3 Jul 2010 11:02:10 +0000 Subject: Kill global variables, constants and functions if local scope suffices Constify variables where possible. Initialize programmer-related variables explicitly in programmer_init to allow running programmer_init from a clean state after programmer_shutdown. Prohibit registering programmer shutdown functions before init or after shutdown. Kill some dead code. Rename global variables with namespace-polluting names. Use a previously unused locking helper function in sst49lfxxxc.c. This is needed for libflashrom. Effects on the binary size of flashrom are minimal (300 bytes shrinkage), but the data section shrinks by 4384 bytes, and that's a good thing if flashrom is operating in constrained envionments. Corresponding to flashrom svn r1068.
