* ich_descriptors: Update for Intel SkylakeNico Huber2017-07-283-159/+261
| | | | | | | | | | | | | | | | | | | | | | | Interpretation of component clocks changed. Also more regions and more masters are supported now. The number of regions (NR) is now static per chipset (10 in the 100 Series case) and not coded into the descriptor any more. v2: o Use guess_ich_chipset() for read_ich_descriptors_from_dump(). o Update region extraction in `ich_descriptors_tool`. TEST=Run `ich_descriptors_tool` over a 100 Series dump and checked that output looks sane. Run `ich_descriptors_tool` over dumps of five different older systems (1 x Sandy Bridge, 3 x Ivy Bridge, 1 x Haswell). Beside whitespace changes, regions not accounted by `NR` are not printed any more.

* ich_descriptors: Add function to guess chipset versionNico Huber2017-07-282-3/+66
| | | | | | | | | | | | | | | | | Add guess_ich_chipset() that takes fields from a descriptor dump and returns the lowest possible chipset version. Intel did several incompatible changes to the descriptor through the years. However, they forgot to add a version number. So we have to apply some heuristics to detect the chipset version in case of exter- nal flashing.

* ichspi: Add support for Intel SkylakeNico Huber2017-07-283-87/+233
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Sunrise Point PCH, paired with Skylake, has some minor changes in the HW sequencing interface: * Support for more flash regions moved PR* registers * Only 4KiB erase blocks are supported by the primary erase command * A second erase command for 64KiB pages was added * More commands were added for status register access etc. * A "Dedicated Lock Bits" register was added No support for the new commands was added. The SW sequencing interface seems to have moved register location and is not supported any more officially. It's also untested. Changes are loosely based on the Skylake support commit in Chromium OS by Ramya Vijaykumar: commit a9a64f9e4d52c39fcd3c5f7d7b88065baed189b1 Author: Ramya Vijaykumar <ramya.vijaykumar@intel.com> flashrom: Add Skylake platform support Change-Id: I0f4565a3c39f5fe3aec4fc8863605cebed1ad4ee Signed-off-by: Nico Huber <nico.huber@secunet.com> Reviewed-on: https://review.coreboot.org/18962 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: David Hendricks <david.hendricks@gmail.com> Reviewed-by: Youness Alaoui <snifikino@gmail.com>
* chipset_enable: Add support for Intel Skylake / KabylakeNico Huber2017-07-282-7/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All publicly known Skylake / Kabylake / Sunrise Point PCH variants share the same register interface [1..6]. Although all SPI configu- ration is now done through the SPI PCI device 1f.5, we can't probe for it directly since its PCI vendor and device IDs are usually hid- den. To work around the hidden IDs, we use another PCI accessor that doesn't rely on the OS seeing the PCI device. This handles SPI flashes only. While booting from LPC is still sup- ported, it seems nobody uses it any more. Some additional PCI IDs were gathered from driveridentifier.com. TEST=Compiled with B150 set to NT (instead of BAD) and checked for sane register readings.

* Add functions to read/erase/write/verify by layoutNico Huber2017-06-032-0/+352
| | | | | | | | | | | | | | | | | | | | | | | | | | Inspired by Lynxis' related work, this implements a foundation for layout based flash access. All operations iterate over the given layout regions. Erase and write then walk, per region, over all erase blocks in an inner loop (which might not be what we want, see note on optimization below). Special care has been taken that flash content is merged properly, in case an erase block is only partially covered by a layout region or even affects mul- tiple regions. A note on performance: In the case an erase block affects multiple regions, it will probably be read, erased and written for each region. Another approach would be to walk all erase blocks once and check for each erase block which regions it touches (i.e. for each erase block, merge data pontentially from the flash and all layout regions, then flash the combined data). That might result in cleaner code. I haven't tried it yet, though.

* Move register decodes into enable_flash_ich_handle_gcs()Nico Huber2017-04-251-4/+18
| | | | | | | | | | | | | | | | | | GCS was decoded partly inside, partly outside this function. The decoding of `top_swap` was off, since passing a `uint8_t` as `bool` doesn't magically check bit0 only. While we are at it, rename this void function to enable_flash_ich_ report_gcs() as it's not doing anything. Beside debug output it doesn't have any side effects.

* Fix fscanf format string security bug in layout.cCarl-Daniel Hailfinger2016-03-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | An internal security audit of the flashrom project by Carl-Daniel Hailfinger found a buffer overflow bug present in all flashrom versions since the year 2005. This bug was independently found and reported to flashrom.org by Cosmin Gorgovan a few days ago. A buffer on the stack and a buffer on the heap are affected by the overflow caused by an incorrect fscanf format string. The buffer overflow can only be triggered if the optional layout feature is used and if the user manually specifies a specially crafted layout file on the command line. Command line parsing and flash image handling do not trigger the buggy code path. Most usage of flashrom does not involve layout files. The fix in this commit (changed fscanf format string) can be applied to layout.c of all past flashrom versions. Corresponding to flashrom svn r1953.

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. Thanks to Uwe Hermann for reporting and testing. - Some other small changes to clean up whitespace and fix some warnings from Debian's lintian. Corresponding to flashrom svn r1951.
