* remove compile guardsThomas Heijligen2021-09-261-4/+0
| | | | | | | | | | | | | The build system handles the decision when to build a file. Extra compile guards for the source files are not necessary.

* mcp6x_spi.c: Refactor singleton states into reentrant patternAnastasia Klimchuk2021-06-031-23/+56
| | | | | | | | | | | | | | | | | | | | | Move global singleton states into a struct and store within the bitbang_spi_master data field for the life-time of the driver. This patch also drops `mcp6x` and `mcp` prefixes from spi data struct members. 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.

* 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.

* 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").

* SPI bitbanging: request/release busCarl-Daniel Hailfinger2010-09-151-9/+2
| | | | | | | | | | | | | | | | | | | | | | | | | SPI bitbanging on devices which speak SPI natively has a dual-use problem: We need to shut down normal SPI operations to do the bitbanging ourselves. Once we're done, it makes a lot of sense to reenable "normal" SPI operations again. Add request_bus/release_bus functions to struct bitbang_spi_master. Add a bitbang shutdown function (not used yet). Change MCP SPI and Intel NIC SPI to use the new request/release bus infrastructure. Cosmetic changes to a few error messages (80 column limit). There are multiple possible strategies for bus request/release: - Request at the start of a SPI command, release immediately afterwards. - Request at the start of a SPI multicommand, release once all commands of the multicommand are done. - Request on programmer init, release on shutdown. Each strategy has its own advantages. For now, we will stay with the first strategy which worked fine so far. Corresponding to flashrom svn r1171.
