* flashrom.c: Make 'chip_to_probe' a param to probe_flash()Edward O'Callaghan2022-11-061-8/+15
| | | | | | | | | | | | | | | | | Apart from the very bespoke case of 'probe_w29ee011()' the override 'chip_to_probe' name is a nature parameter to 'probe_flash()'. However we can deal with w29ee011 by providing a probe specific validation function to check if the chip can indeed be overriden. TEST=`./flashrom -p internal --flash-name`.

* tree: provide flashrom context into programmer_delay()Alexander Goncharov2022-10-171-9/+9
| | | | | | | | | | | | | | | | | Modify the `programmer_delay` function signature to allow passing the flashrom context. Programmers that depend on internal delay should provide NULL as a context. The use of this function parameter will be introduced in CB:67393.

* Use struct flashctx instead of struct flashchip for flash chip accessCarl-Daniel Hailfinger2011-12-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | Struct flashchip is used only for the flashchips array and for operations which do not access hardware, e.g. printing a list of supported flash chips. struct flashctx (flash context) contains all data available in struct flashchip, but it also contains runtime information like mapping addresses. struct flashctx is expected to grow additional members over time, a prime candidate being programmer info. struct flashctx contains all of struct flashchip with identical member layout, but struct flashctx has additional members at the end. The separation between struct flashchip/flashctx shrinks the memory requirement of the big flashchips array and allows future extension of flashctx without having to worry about bloat.

| | | | | | | | | | | | | | | | | | | | | | This is related to the spi split patch as discussed in: http://www.flashrom.org/pipermail/flashrom/2010-February/thread.html#2364 the old commit (r914) log notes: "Some of the spi programmer drivers required chipdrivers.h, needs fixing later: it87spi.c ichspi.c sb600spi.c wbsio_spi.c buspirate_spi.c ft2232spi.c bitbang_spi.c dediprog.c" there still remain a few cases where chipdrivers.h is needed: dediprog.c (spi_read_chunked and spi_write_chunked) it87spi.c (due to spi_write_enable and spi_read_status_register) wbsio_spi.c (spi_programmer registration only) besides that, there are also non-spi files that do not need it. also, add flash.h to chipdrivers.h because it uses some types of it and remove flashchips.h from print.c Corresponding to flashrom svn r1414.

| | | | | | | | | | | | According to the datasheets probe_w29ee011 is the only valid probe function for those chips, but we have reports where those chips were only detected with probe_jedec, and thus we assume that our datasheets only cover an earlier stepping.

* 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.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-1/+1
| | | | | | | | | | | | | | | | | | | 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 Hailfinger2009-03-051-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add support for AMIC Technology A49LF040A and do not probe W29EE011 anymoreJens Kuehnel2008-06-181-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | Jens sent the first patch that added A49LF040A to flash.h and flashchips.c using _jedec and _49lf040 functions. An issue was found with probe_w29ee011() for the Winbond W29EE011, which caused the A49LF040A to no longer respond to any commands. Ward made a patch to disable probing by default for the W29EE011 following some discussion. Using -c W29EE011 will make flashrom probe for the chip. Peter did some more datasheet diving and found that the Pm49FL00x functions suited this chip quite well because of the block locking registers in A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3. Ward confirmed that this works on alix.2c3 too. Corresponding to flashrom svn r260 and coreboot v2 svn r3368.
