Change in flashrom[staging]: ichspi: Add support for Intel Skylake

by Nico Huber (Code Review)

Nico Huber has submitted this change and it was merged. ( https://review.coreboot.org/18962 ) Change subject: ichspi: Add support for Intel Skylake ...................................................................... ichspi: Add support for Intel Skylake 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(a)intel.com> flashrom: Add Skylake platform support Change-Id: I0f4565a3c39f5fe3aec4fc8863605cebed1ad4ee Signed-off-by: Nico Huber <nico.huber(a)secunet.com> Reviewed-on: https://review.coreboot.org/18962 Tested-by: build bot (Jenkins) <no-reply(a)coreboot.org> Reviewed-by: David Hendricks <david.hendricks(a)gmail.com> Reviewed-by: Youness Alaoui <snifikino(a)gmail.com> --- M ich_descriptors.c M ich_descriptors.h M ichspi.c 3 files changed, 233 insertions(+), 87 deletions(-) Approvals: build bot (Jenkins): Verified David Hendricks: Looks good to me, approved Youness Alaoui: Looks good to me, but someone else must approve diff --git a/ich_descriptors.c b/ich_descriptors.c index a12022c..1fc8835 100644 --- a/ich_descriptors.c +++ b/ich_descriptors.c @@ -824,6 +824,7 @@ case CHIPSET_8_SERIES_WELLSBURG: case CHIPSET_9_SERIES_WILDCAT_POINT: case CHIPSET_9_SERIES_WILDCAT_POINT_LP: + case CHIPSET_100_SERIES_SUNRISE_POINT: if (idx == 0) { size_enc = desc->component.dens_new.comp1_density;

Change in flashrom[staging]: chipset_enable: Add support for Intel Skylake / Kabylake

by Nico Huber (Code Review)

Nico Huber has submitted this change and it was merged. ( https://review.coreboot.org/18925 ) Change subject: chipset_enable: Add support for Intel Skylake / Kabylake ...................................................................... chipset_enable: Add support for Intel Skylake / Kabylake 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.

Change in flashrom[staging]: rpci: Use pci_dev struct pointer to avoid API breaks

by Youness Alaoui (Code Review)

Hello David Hendricks, Paul Menzel, build bot (Jenkins), Nico Huber, I'd like you to reexamine a change. Please visit https://review.coreboot.org/20784 to look at the new patch set (#3). Change subject: rpci: Use pci_dev struct pointer to avoid API breaks ...................................................................... rpci: Use pci_dev struct pointer to avoid API breaks The pci_dev structure is never meant to be used as is, but always as a pointer. By using the struct itself in undo_pci_write_data, we are risking data corruption, or buffer overflows if the structure size changes. This is especially apparent on my system where flashrom segfaults because I compile it with pciutils 3.3.0 and I run it on a system with pciutils 3.5.2. The struture size is different and causes a struct with the wrong size to be sent to the library, with invalid internal field values. This has been discovered and discussed in Change ID 18925 [1] [1] https://review.coreboot.org/#/c/18925/ Change-Id: Icde2e587992ba964d4ff92c33aa659850ba06298 Signed-off-by: Youness Alaoui <kakaroto(a)kakaroto.homelinux.net> --- M pcidev.c M programmer.h 2 files changed, 20 insertions(+), 9 deletions(-) git pull ssh://review.coreboot.org:29418/flashrom refs/changes/84/20784/3 -- To view, visit https://review.coreboot.org/20784 To unsubscribe, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: staging Gerrit-MessageType: newpatchset Gerrit-Change-Id: Icde2e587992ba964d4ff92c33aa659850ba06298 Gerrit-Change-Number: 20784 Gerrit-PatchSet: 3 Gerrit-Owner: Youness Alaoui <snifikino(a)gmail.com> Gerrit-Reviewer: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: Paul Menzel <paulepanter(a)users.sourceforge.net> Gerrit-Reviewer: Youness Alaoui <snifikino(a)gmail.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org>
