* Fix and improve libpayload platform supportoxygene2011-03-081-0/+1
| | | | | | | | | | | | | | | - Fix various minor compile issues (eg. include necessary standard headers) - Fix compilation of libpayload code paths - Provide libpayload support in Makefile - Add make target "libflashrom.a" which links non-CLI code to static library Signed-off-by: Patrick Georgi <patrick.georgi@secunet.com> Tested-with-DOS-crosscompiler-by: Idwer Vollering <vidwer@gmail.com> Acked-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> git-svn-id: https://code.coreboot.org/svn/flashrom/trunk@1280 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1

| | | | | | | | | | | | | This patch fixes the "using plain integer as NULL pointer" warnings generated by running sparse on the flashrom source.

* Kill global variables, constants and functions if local scope suffices.hailfinger2010-07-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove unneeded #include statements completely.hailfinger2010-05-301-2/+3
| | | | | | | | | | | | | | | | unistd.h was only used to get a definition of NULL in all files. Add our own NULL #define and remove unistd.h from flash.h stdio.h has no place in flash.h, it should be included only in files which really need it. Add #include statements in individual .c files where needed. Replace a few printf with msg_* to eliminate the need for stdio.h.

* The current delay loop calculation is still from revision 1 of flashrom,hailfinger2010-03-311-13/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and since then it had a logic bug which caused all delays to be twice as long as intended. Fix the delay duration. Protect against delay loop overflows. Detect a non-working delay loop. Change the delay loop itself to ensure clever compiler optimizers won't eliminate it (as happens with clang/llvm in the current code). Some people suggested machine-specific asm, but the empty asm statement with the loop counter as register/memory input has the benefit of being perfectly cross-platform and working in gcc and clang. If time goes backwards (catastrophical NTP time difference, manual time change), timing measurements were shot because the new-old time subtraction yielded negative numbers which weren't handled correctly because the variable is unsigned. Work around that issue (a fix is mathematically impossible). If time goes forward too fast, pick the biggest possible timing measurement with a guaranteed overflow avoidance for all timing calculations. Check four times if the calculated timing is at most 10% too fast. This addresses OS scheduler interactions, e.g. being scheduled out during measurement which inflates measurements. If the timing looks like garbage, recalculate the timer values up to four times before giving up. Avoid division by zero in rare cases where timing measurements for a 250 ms delay returned 0 us elapsed.

The code which is now in udelay.c was split out from flash_rom.c in r1428, and flash_rom.c, in turn, has been around since the beginning and had a 'Copyright 2000 Silicon Integrated System Corporation' line as well as the usual GPLv2-or-later license header.
