* Add RES/REMS support to all dummyflasher emulated chips as a test caseCarl-Daniel Hailfinger2012-08-301-10/+47
| | | | | | | | | | Fix a few odd corner cases in RES/REMS support in dummyflasher emulation which became noticeable once RES/REMS was used heavily. Corresponding to flashrom svn r1589.

* Let the programmer driver decide how to do AAI transfersNico Huber2012-06-151-0/+1
| | | | | | | | | | | | | | | | Currently spi_aai_write() is implemented without an abstraction mechanism for the programmer driver. This adds another function pointer 'write_aai' to struct spi_programmer, which is set to default_spi_write_aai (renamed spi_aai_write) for all programmers for now. A patch which utilises this abstraction in the dediprog driver will follow. Corresponding to flashrom svn r1543.

* dummyflasher.c: add support for SFDP by adding a new emulator chip: MX25L6436Stefan Tauner2012-05-071-11/+98
| | | | | | | | | | | The chip features a complete 1.0 SFDP JEDEC flash parameter table and also a vendor-specific extension table (defining voltages, lock bits etc). NB: the MX25L6436 uses the same RDID as the MX25L6405. Corresponding to flashrom svn r1534.

* Use struct flashctx instead of struct flashchip for flash chip accessCarl-Daniel Hailfinger2011-12-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | 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.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-15/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch attempts to resolve some programmer shutdown ordering issues by having the programmer init functions register shutdown callbacks explicitly wherever it makes most sense. Before, assumptions were made that could lead to the internal programmer's state changing before the external programmer could be shut down properly. Now, each programmer cleans up after itself and (hopefully) performs each operation in the correct order. As a side-effect, this patch gives us a better usage model for reverse operations such as rpci_* and rmmio_*. In the long-run, this should make reversing the initialization process easier to understand, less tedious, and less error-prone. In short, this patch does the following: - Registers a shutdown callback during initialization for each programmer. - Kills the .shutdown function pointer from programmer_entry struct. Also, make most shutdown functions static. - Adds a few minor clean-ups and corrections (e.g. missing physunmap() calls).

* Kill central list of SPI programmersMichael Karcher2011-05-111-4/+16
| | | | | | | | | | | | | | | | | | Remove the array spi_programmer, replace it by dynamic registration instead. Also initially start with no busses supported, and switch to the default non-SPI only for the internal programmer. Also this patch changes the initialization for the buses_supported variable from "everything-except-SPI" to "nothing". All programmers have to set the bus type on their own, and this enables register_spi_programmer to just add the SPI both for on-board SPI interfaces (where the internal programmer already detected the other bus types), as well as for external programmers (where we have the default "none").

* Add SPI multicommand infrastructureCarl-Daniel Hailfinger2009-07-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some SPI opcodes need to be sent in direct succession after each other without any chip deselect happening in between. A prominent example is WREN (Write Enable) directly before PP (Page Program). Intel calls the first opcode in such a row "preopcode". Right now, we ignore the direct succession requirement completely and it works pretty well because most onboard SPI masters have a timing or heuristics which make the problem disappear. The FT2232 SPI flasher is different. Since it is an external flasher, timing is very different to what we can expect from onboard flashers and this leads to failure at slow speeds. This patch allows any function to submit multiple SPI commands in a stream to any flasher. Support in the individual flashers isn't implemented yet, so there is one generic function which passes the each command in the stream one-by-one to the command functions of the selected SPI flash driver.

* Add bus type support to the dummy external programmerCarl-Daniel Hailfinger2009-06-011-1/+37
| | | | | | | | | | | | | | | The syntax is explained in the man page. Example: flashrom -p dummy=lpc,fwh Tested, works perfectly. ;-) As a nice benefit, it allows easy testing of the "probe only compatible flashes" patch. Corresponding to flashrom svn r559.

* Add bus type annotation to struct flashchipsCarl-Daniel Hailfinger2009-05-311-1/+1
| | | | | | | | | | | | | | | | | | | Right now, the annotation only differentiates between SPI and non-SPI. Anyone who knows more about a specific flash chip should feel free to update it. The existing flashbus variable was abused to denote the SPI controller type. Use an aptly named variable for that purpose. Once this patch is merged, the chipset/programmer init functions can set supported flash chip types and flashrom can automatically select only matching probe/read/erase/write functions. A side benefit of that will be the elimination of the Winbond W29EE011 vs. AMIC A49LF040A conflict. Corresponding to flashrom svn r556.

* Introduce a type "chipaddr" to abstract the offsets within flash regionsCarl-Daniel Hailfinger2009-05-161-12/+12
| | | | | | | | | | | | | | | | | | | 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.

* Abstract mapping/unmapping of flash regionsCarl-Daniel Hailfinger2009-05-111-0/+13
| | | | | | | | | | | | | | | | Flash mapping/unmapping was performed without an abstraction layer, so even the dummy flasher caused memory mappings to be set up. Add map/unmap functions to the external flasher abstraction. Fix a possible scribble-over-low-memory corner case which fortunately never triggered so far. With this patch, --programmer dummy works fine as non-root. Corresponding to flashrom svn r493.
