* it85spi.c: Inline it85xx_spi_common_init()Anastasia Klimchuk2021-01-211-52/+45
| | | | | | | | | | | | | | | | | Inline it85xx_spi_common_init() to single call site of it85xx_spi_init() as the construction is a single phase one. This allows for less cyclomatic complexity by validating early and initialisation at the eulogy of the one entry-point to the driver.

* const'ify flashctx to align signatures with cros flashromEdward O'Callaghan2020-04-301-2/+2
| | | | | | | | | | | | | | | | 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.

* Use shutdown callback mechanism to shutdown programmersDavid Hendricks2011-06-141-7/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Karcher2011-05-111-5/+16
| | | | | | | | | | | | | | | | | | 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 more than one Super I/O or EC per machineCarl-Daniel Hailfinger2011-04-271-68/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Flashrom currently only supports exactly one Super I/O or Embedded Controller, and this means quite a few notebooks and a small subset of desktop/server boards cannot be handled reliably and easily. Allow detection and initialization of up to 3 Super I/O and/or EC chips. WARNING! If a Super I/O or EC responds on multiple ports (0x2e and 0x4e), the code will do the wrong thing (namely, initialize the hardware twice). I have no idea if we should handle such situations, and whether we should ignore the second chip with identical ID or not. Initializing the hardware twice for the IT87* family is _not_ a problem, but I don't know how well IT85* can handle it (and whether IT85* would listen at more than one port anyway).

There are a few caveats, though: - The boot BIOS straps register must be modified to select LPC.
