* programmer: Smoothen register_par_master APIAnastasia Klimchuk2021-05-231-1/+4
| | | | | | | | | | | | | | | It was impossible to register a const struct par_master that would point to dynamically allocated `data`. Fix that so that we won't have to create more mutable globals.

* programmer.h: Convert anon union to anon structEdward O'Callaghan2021-05-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | Convert the anon union of registered masters in the mst field of the flashctx to a anon struct. If we are going to dereference a pointer there in an undefined way we should crash and not plow ahead with invalid memory. The user of the registered_masters type is therefore responsible for querying the buses_supported field before attempting to dereference a ptr field in the anon struct.

Spotted by Pablo Cases. - Add an additional SMBus controller revision to identify another Yangtze model. Thanks to Dan Christensen for reporting this issue. - dediprog: add missing include for stdlib.h. This fixes (at least) building on FreeBSD and DragonflyBSD with gcc. - Remove references to struct pci_filter from programmer.h. It is only needed in internal.c where it has a complete type. Having it in programmer.h provokes a warning by some old versions of gcc. - Tiny other stuff. Corresponding to flashrom svn r1879.

* Rename programmer registration functionsCarl-Daniel Hailfinger2014-07-191-21/+21
| | | | | | | | | | | | 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.

* Uintptr_t-ify map_flash_region functionsStefan Tauner2013-07-171-1/+1
| | | | | | | | | | | | | | | | | | | Unsigned long is not the right type for manipulating pointer values. Since C99 there are suitable unsigned and signed types available, namely uintptr_t and intptr_t respectively. Use them in functions assigned to programmers' map_flash_region fields and their callers where applicable. This patch also changes the display width of all associated address values in physmap.c to 16/8 hex characters depending on the actual size by introducing a macro PRIxPTR_WIDTH and exploiting printf's * field width specifier.

* Have all programmer init functions register bus masters/programmersCarl-Daniel Hailfinger2011-12-201-23/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

A few internal functions in flash chip drivers had chipaddr parameters which are no longer needed. The lines touched by flashctx changes have been adjusted to 80 columns except in header files.

* Move generic programmer function into newly introduced programmer.cCarl-Daniel Hailfinger2010-01-061-0/+99
Some programmers (most notably FT2232SPI) use fallback_* and noop_*, but those functions lived inside internal.c and were unavailable if no PCI-based programmers were compiled in.
