* Kill global variables, constants and functions if local scope sufficesCarl-Daniel Hailfinger2010-07-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Standardize on using __func__ instead of __FUNCTION__Uwe Hermann2009-09-021-1/+1
| | | | | | | | | | | | | | | The __func__ variant is standardized in C99 and recommended to be used instead of __FUNCTION__ in the gcc info page. Only _very_ old versions of gcc did not know about __func__, but we've been using both __func__ and __FUNCTION__ for a long while now, and nobody complained about this, so all our users seem to use recent enough compilers.

* Flashrom only checks for very few chips if the erase workedCarl-Daniel Hailfinger2009-06-151-2/+15
| | | | | | | | | | | | | | | | | | | And even when it checks if the erase worked, the result of that check is often ignored. Convert all erase functions and actually check return codes almost everywhere. Check inside all erase_* routines if erase worked, not outside. erase_sector_jedec and erase_block_jedec have changed prototypes to enable erase checking.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-8/+8
| | | | | | | | | | | | | | | | | | | Use chipaddr instead of volatile uint8_t * because when we access chips in external flashers, they are not accessed via pointers at all. Benefits: This allows us to differentiate between volatile machine memory accesses and flash chip accesses. It also enforces usage of chip_{read,write}[bwl] to access flash chips, so nobody will unintentionally use pointers to access chips anymore. Some unneeded casts are removed as well. Grepping for chip operations and machine memory operations doesn't yield any false positives anymore. Compile tested on 32 bit and 64 bit Linux. Corresponding to flashrom svn r519.

* Reduce use of volatile variablesCarl-Daniel Hailfinger2009-03-061-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During the conversion of flash chip accesses to helper functions, I spotted assignments to volatile variables which were neither placed inside the mmapped ROM area nor were they counters. Due to the use of accessor functions, volatile usage can be reduced significantly because the accessor functions take care of actually performing the reads/writes correctly. The following semantic patch spotted them (linebreak in python string for readability reasons, please remove before usage): @r exists@ expression b; typedef uint8_t; volatile uint8_t a; position p1; @@ a@p1 = readb(b); @script:python@ p1 << r.p1; a << r.a; b << r.b; @@ print "* file: %s line %s has assignment to unnecessarily volatile variable: %s = readb(%s);" % (p1[0].file, p1[0].line, a, b) Result was: HANDLING: sst28sf040.c * file: sst28sf040.c line 44 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 43 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 42 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 41 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 40 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 39 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 38 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 58 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 57 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 56 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 55 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 54 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 53 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); * file: sst28sf040.c line 52 has assignment to unnecessarily volatile variable: tmp = readb(TODO: Binary); The following semantic patch uses the spatch builtin match printing functionality by prepending a "*" to the line with the pattern: @@ expression b; typedef uint8_t; volatile uint8_t a; @@ * a = readb(b); Result is: HANDLING: sst28sf040.c diff = - tmp = readb(bios + 0x1823); - tmp = readb(bios + 0x1820); - tmp = readb(bios + 0x1822); - tmp = readb(bios + 0x0418); - tmp = readb(bios + 0x041B); - tmp = readb(bios + 0x0419); - tmp = readb(bios + 0x040A); } static __inline__ void unprotect_28sf040(volatile uint8_t *bios) @@ -49,13 +42,6 @@ static __inline__ void unprotect_28sf040 /* ask compiler not to optimize this */ volatile uint8_t tmp; - tmp = readb(bios + 0x1823); - tmp = readb(bios + 0x1820); - tmp = readb(bios + 0x1822); - tmp = readb(bios + 0x0418); - tmp = readb(bios + 0x041B); - tmp = readb(bios + 0x0419); - tmp = readb(bios + 0x041A); } static __inline__ int erase_sector_28sf040(volatile uint8_t *bios, It's arguably a bit easier to read if you get used to the leading "-" for matching lines.

* Use helper functions to access flash chipsCarl-Daniel Hailfinger2009-03-051-25/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Right now we perform direct pointer manipulation without any abstraction to read from and write to memory mapped flash chips. That makes it impossible to drive any flasher which does not mmap the whole chip. Using helper functions readb() and writeb() allows a driver for external flash programmers like Paraflasher to replace readb and writeb with calls to its own chip access routines. This patch has the additional advantage of removing lots of unnecessary casts to volatile uint8_t * and now-superfluous parentheses which caused poor readability. I used the semantic patcher Coccinelle to create this patch. The semantic patch follows: @@ expression a; typedef uint8_t; volatile uint8_t *b; @@ - *(b) = (a); + writeb(a, b); @@ volatile uint8_t *b; @@ - *(b) + readb(b) @@ type T; T b; @@ ( readb | writeb ) (..., - (T) - (b) + b ) In contrast to a sed script, the semantic patch performs type checking before converting anything.
