* 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.

* Remove unneeded #include statements completelyCarl-Daniel Hailfinger2010-05-301-2/+0
| | | | | | | | | | | | | | | 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. Corresponding to flashrom svn r1021.

* Use the register mapping feature bitCarl-Daniel Hailfinger2010-01-091-2/+0
| | | | | | | | | | | | | | | | | | | All functions which just call probe_jedec and then map flash registers are replaced by probe_jedec. All functions which call probe_jedec, map flash registers and do something else can at least eliminate mapping flash registers. Fix logic inversion in probe_jedec to map flash registers on success instead of on failure. Change a few TIMING_IGNORED to TIMING_FIXME where probe_jedec is used.

* Generify jedec functions by introducing an address maskSean Nelson2010-01-041-2/+2
| | | | | | | | | | | | | | | | | The patch converts jedec functions into mask-based generics which can be used for many chip provided the only changes are the addresses are converted from 0x5555/0x2AAA to 0x555/0x2AA or similar. The patch mostly changes jedec.c, but a few other files are changed because they use the jedec functions within their own functions. The patch also adds a copyright line to flashchips.c because of my recent work in converting AMD and Atmel chips to use struct erase_block. Corresponding to flashrom svn r828.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-4/+4
| | | | | | | | | | | | | | | | | | | 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.

* Use helper functions to access flash chipsCarl-Daniel Hailfinger2009-03-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
