* spi: Make 'default_spi_write_aai' the default unless definedEdward O'Callaghan2022-12-211-3/+0
| | | | | | | | | | | | | | | | | | | A NULL func pointer is necessary and sufficient for the condition `NULL func pointer => default_spi_write_aai' as to not need this explicit specification of 'default'. Therefore Drop the explicit need to specify the 'default_spi_write_aai' callback function pointer in the spi_master struct. This is a reasonable default for every other driver in the tree with only a few exceptions. This simplifies the code and driver development.

* drivers: Move (un)map_flash_region to par/spi/opaque_masterJonathon Hall2022-10-081-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | Move (un)map_flash_region function pointers from programmer_entry to par_master, spi_master, and opaque_master. This enables programmers to specify a different mapper per bus, which is needed for the internal programmer. Mapping is closely tied to the way the memory is accessed using the other functions in the bus master structs. Validate that FWH/LPC programmers provide specialized mapping in register_par_master(); this is needed for chips with FEATURE_REGISTERMAP, which only exist on FWH or LPC buses. programmer.c: Update comment in fallback_map(), NULL return is the desired behavior.

This is quite confusing however it turns out FCH chipsets called 'Promontory' contain the so-called SPI100 ip core that uses memory mapping and not a ring buffer for transactions. Typically this is found on both Stoney Ridge and Zen platforms. In light of this, separate out the promontory path into its own callback struct state tracker so that it's implementation does not interfere with previous generations that predate the SPI100 controller. Since there is some life-time state required to track the mapping during between the first attempted read and the final tear-down of the spi master we take the opportunity to avoid static locals and instead implement the functionality in a re-entrant way for follow up clean ups.

| | | | | | | | | | | | | | | | The ChromiumOS flashrom fork has since const'ify flashctx in a few places. This aligns the function signatures to match with downstream to ease forward porting patches out of downstream back into mainline flashrom. This patch is minimum viable alignment and so feedback is welcome.

The previous IDs contained the on-board display adapter which is disabled when a dedicated graphics card is installed. - Add a note to the README how to overcome the clang warning if only a single programmer is enabled. - Fix some typo and manpage problems found by lintian - r1920 introduced some explicit calls to pkg-config instead of $(PKG_CONFIG). This patch corrects that. - Make MS-7094 (K8T Neo2-F V2.0) board enable less contestable. Previous PCI IDs were board-specific but ot the other of devices that could be disabled by the firmware or that vary among hardware revions. There are no good alternatives available. However, since we always have a DMI decoder available now, we can use non-board-specific devices without taking risks.
