* ogp_spi.c: Refactor singleton states into reentrant patternAnastasia Klimchuk2021-06-031-12/+46
| | | | | | | | | | | | | | | | | | Move global singleton states into a struct and store within the bitbang_spi_master data field for the life-time of the driver. This is one of the steps on the way to move spi_master data memory management behind the initialisation API, for more context see other patches under the same topic "register_master_api".

* Rename programmer registration functionsCarl-Daniel Hailfinger2014-07-191-1/+1
| | | | | | | | | | | | Register_programmer suggests that we register a programmer. However, that function registers a master for a given bus type, and a programmer may support multiple masters (e.g. SPI, FWH). Rename a few other functions to be more consistent.

* Unify PCI init and let pcidev clean itself upStefan Tauner2013-01-041-2/+0
| | | | | | | | | | | | | | | | | | | Previously the internal programmer used its own code to initialize pcilib. This patch extracts the common code from the internal programmer and pcidev_init() into pcidev_init_common(). This fixes the non-existent PCI cleanup of the internal programmer and adds an additional safety by checking for an already existing PCI context. We got a nice shutdown function registration infrastructure, but did not use it very wisely. Instead we added shutdown functions to a myriad of programmers unnecessarily. In this patch we get rid of those that do only call pci_cleanup(pacc) by adding a shutdown function the pcidev.c itself that gets registered by pcidev_init(). Corresponding to flashrom svn r1642.

* Unify usbdev_status and pcidev_status into dev_entryStefan Tauner2012-12-271-1/+1
| | | | | | | | | | | | | | | | | | | Once upon a time usbdev_status was created for the ft2232 programmer. Its IDs are semantically different to pcidev_status because they indicate USB instead of PCI IDs, but apart from that both data structures are equal. This change makes life easier for everything involved in handling and printing the status of devices that is noted in those structures by combining them into dev_entry. It is still possible to distinguish between PCI and USB devices indirectly by using the struct programmer's type field. Also, add a programmer column to the PCI and USB devices lists.

* Automatically release I/O permissions on shutdownCarl-Daniel Hailfinger2012-07-211-2/+2
| | | | | | | | | | | | | | | | | | | | | Get_io_perms() is renamed to rget_io_perms() and automatically registers a function to release I/O permissions on shutdown. Actually release I/O permissions on Solaris and iopl()-supporting operating systems like Linux. This patch fixes quite a few programmers which forgot to release I/O permissions on shutdown, and it simplifies the shutdown and error handling code for all others. Do not call exit(1) if I/O permissions are denied and return an error instead. This part of the patch was written by Niklas Söderlund. Corresponding to flashrom svn r1551.

* Have all programmer init functions register bus masters/programmersCarl-Daniel Hailfinger2011-12-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | All programmer types (Parallel, SPI, Opaque) now register themselves into a generic programmer list and probing is now programmer-centric instead of chip-centric. Registering multiple SPI/... masters at the same time is now possible without any problems. Handling multiple flash chips is still unchanged, but now we have the infrastructure to deal with "dual BIOS" and "one flash behind southbridge and one flash behind EC" sanely. A nice side effect is that this patch kills quite a few global variables and improves the situation for libflashrom. Hint for developers: struct {spi,par,opaque}_programmer now have a void *data pointer to store any additional programmer-specific data, e.g. hardware configuration info. Note: flashrom -f -c FOO -r forced_read.bin does not work anymore. We have to find an architecturally clean way to solve this. Corresponding to flashrom svn r1475.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Karcher2011-05-111-3/+0
| | | | | | | | | | | | | | | | | | 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 support for the Open Graphics Project development card, OGD1, as a SPI ↵Mark Marshall2010-12-031-0/+145
flash programmer The project is in the the process of designing and making a complete, open source, graphics card. More info at http://wiki.opengraphics.org. The first development card is a PCI add in card containing a couple of FPGAs and a couple of serial flash chips (amongst other things). The FPGAs are called XP10 and S3 (their part numbers). The XP10 contains its own flash and does not need to be programmed by flashrom - it ensures that the device can enumerate on the PCI bus without needing further configuration. The larger FPGA is the S3. This is configured from a large SPI flash (2 MBytes). The second SPI flash is used to store the VGA BIOS. It is smaller (128 KBytes). This patch adds support for programming either of the two SPI flash chips. The programmer device takes one configuration option which selects which of the two flash chips is accessed. This must be set to either "cprom" or "bprom". (The project refers to the two chips as "cprom" / "bprom", "s3" and "bios" are more readable alternatives). Add support for SST SST25VF010 (REMS). Mark SST SST25VF016B as tested for write. Corresponding to flashrom svn r1241.
