* Use __func__ instead of __FUNCTION__ as we do elsewhere.uwe2011-07-291-14/+12
| | | | | | | | | | | | | | The __func__ variant is standardized in C99 and recommended to be used instead of __FUNCTION__ in the gcc info page. See also r711 where we did the same change.

* Use shutdown callback mechanism to shutdown programmersdhendrix2011-06-141-7/+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 programmersmkarcher2011-05-111-5/+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 machine.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).

* Various IT85* cleanups and fixes.hailfinger2011-03-081-16/+27
| | | | | | | | | | | | | | | | | | | | | Fix a few typos. Change the EC memory region mapping name. Drop unused function parameter. Use mmio_writeb()/mmio_readb() to get reliable access to volatile memory locations instead of plain pointer access which is optimized away by gcc. Use own it85_* SPI high-level chip read/write functions instead of relying on unrelated ICH functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | flashrom-chromium tree. This code has been deployed and tested to work on the Cr-48. There are a few caveats, though: - The boot BIOS straps register must be modified to select LPC. This can be done with the "select_bbs.sh" script (Install iotools at http://code.google.com/p/iotools/ before using select_bbs). - It is very important to disable power management daemons before running flashrom on this EC. I commented out the brute force method we use in the Chromium OS branch that disables powerd, since IIRC Carl-Daniel has a better approach in the works. - Due to dependencies which may be introduced by the OEM/ODM EC firmware, the code is not guaranteed to work for anything other than the Cr-48.

The patch was developed by Google. It was tested for IT8500E on a Chrome OS platform and may require modification depending on ODM/OEM customization and EC firmware version.
