* Fixup of r1397Carl-Daniel Hailfinger2011-08-151-2/+4
| | | | | | | | | | | | | | - Mixing uninitialized and initialized local variables leads to confusion. - ft2232_spi error cases should have gotten some error handling, and that's the reason the curly braces were there. - Fixing typos/wording in some places would have been nice given that those places were touched anyway.

| | | | | | | | | | | | Also, indentation fixes, e.g. due to conversion to msg_*, use ARRAY_SIZE where possible, wrap overly long line, etc. Compile-tested. There should be no functional changes.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-19/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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). TODO: Remove forward declaration of serprog_shutdown() (added to simplify diff) Corresponding to flashrom svn r1338.

* Kill central list of SPI programmersMichael Karcher2011-05-111-5/+14
| | | | | | | | | | | | | | | | | | 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").

* Secret knowledge is cool, but public knowledge is betterCarl-Daniel Hailfinger2011-01-201-5/+117
| | | | | | | | | | | | | | | Implement all Dediprog commands found in USB traces, even if their purpose is not yet known. Annotate unknown commands with info about the call sequence they are embedded in and the firmware version of the log. Add a new shutdown command for firmware 5.x (of which Stefan thinks it's "switch the Pass light on" hence it is called late in the game) Corresponding to flashrom svn r1254.

* Add chunked write ability to the Dediprog SF100 driverCarl-Daniel Hailfinger2010-11-231-1/+7
| | | | | | | | | | | | | | Please note that the write speedup only applies to chips which have SPI page write (i.e. chips using spi_chip_write_256). This is a quick fix for write speed until I get around to implementing full bulk SPI write support. Corresponding to flashrom svn r1235.

* Support bulk read on Dediprog SF100Carl-Daniel Hailfinger2010-11-161-6/+109
| | | | | | | | | | | | | | | | | | | Should result in native speed for plain read and erase. Should result in a measurable speedup for writes due to a fast verify. Packet size is 512 bytes. Depending on your USB hardware and the Dediprog firmware version, this may not work at all. That said, it worked on the hardware we tested. Add lots of error checking where it was missing before.

| | | | | | | | | | | | | | | | | | | | | Programmer specific functions are of absolutely no interest to any file except those dealing with programmer specific actions (special SPI commands and the generic core).

* Kill global variables, constants and functions if local scope sufficesCarl-Daniel Hailfinger2010-07-031-16/+20
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Dediprog SF100 supportCarl-Daniel Hailfinger2010-01-191-0/+388
Reverse engineered from USB logs. I never touched that programmer nor did I ever see the associated software. Disabled by default until it is complete. The driver needs to be hooked up to the SPI core before it will do anything besides init and diagnostics. I successfully reverse engineered all commands, but some are still somewhat magic. Logs from "flashrom -p dediprog -V" are appreciated. Probe and read should work, erase/write is expected to explode. The programmer will set voltage to 0 on exit. Thanks a lot to Stefan Reinauer and Patrick Georgi for providing USB logs and for testing the result. Corresponding to flashrom svn r870.
