( https://review.coreboot.org/c/flashrom/+/56023 ) Change subject: board_enable.c: Add ME unlock function for Clevo laptops ...................................................................... Patch Set 15: (1 comment) File board_enable.c: https://review.coreboot.org/c/flashrom/+/56023/comment/0455bd99_c1dfb970 PS2, Line 2339: return 0; I gave it a try and extracted a separate tool in CB:63416, the question is whether it's OK for it to link to 48 source files of flashrom... All of them are needed for successful linking, I've added an SVG depicting module dependencies to show how interdependent everything is. > It should be possible to use the board_status infrastructure without going through the programmer/flash API. Even pcidev.c depends on programmer, because it uses register_shutdown() and thus brings in half of flashrom. Please take a look and say what you think about a tool like that. -- To view, visit https://review.coreboot.org/c/flashrom/+/56023 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I6bf1c40900aa674e3ea4f6add12dae8b73759fbb Gerrit-Change-Number: 56023 Gerrit-PatchSet: 15 Gerrit-Owner: Michał Żygowski <michal.zygowski(a)3mdeb.com> Gerrit-Reviewer: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Angel Pons <th3fanbus(a)gmail.com> Gerrit-CC: Arthur Heymans <arthur(a)aheymans.xyz> Gerrit-CC: Felix Singer <felixsinger(a)posteo.net> Gerrit-CC: Michael Niewöhner <foss(a)mniewoehner.de> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-CC: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Attention: Felix Singer <felixsinger(a)posteo.net> Gerrit-Attention: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Michał Żygowski <michal.zygowski(a)3mdeb.com> Gerrit-Attention: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Attention: Arthur Heymans <arthur(a)aheymans.xyz> Gerrit-Attention: Michael Niewöhner <foss(a)mniewoehner.de> Gerrit-Comment-Date: Wed, 06 Apr 2022 19:17:43 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Nico Huber <nico.h(a)gmx.de> Comment-In-Reply-To: Michał Żygowski <michal.zygowski(a)3mdeb.com> Comment-In-Reply-To: Angel Pons <th3fanbus(a)gmail.com> Comment-In-Reply-To: Michael Niewöhner <foss(a)mniewoehner.de> Gerrit-MessageType: comment

Change in flashrom[master]: [WIP] add me_unlock_tool
by Sergii Dmytruk (Code Review) 06 Apr '22

06 Apr '22

Sergii Dmytruk has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/63416 ) Change subject: [WIP] add me_unlock_tool ...................................................................... [WIP] add me_unlock_tool This is an alternative take on CB:56023 that implement ME unlocking in a separate tool. The only problem is: it links to a half of flashrom sources... Another issue is creation of a fake programmer for register_shutdown() to work. With the current state of the codebase, it's virtually impossible to do better. Check SVG file in the commit for a graph depicting import/export of function symbols from a subset of object files used by this tool.

Change in flashrom[master]: ichspi: Rename HSFC_FDBC -> HSFC_FDBC_MASK
by Anastasia Klimchuk (Code Review) 06 Apr '22

06 Apr '22

Attention is currently required from: Subrata Banik, Nico Huber, Angel Pons. Anastasia Klimchuk has posted comments on this change. ( https://review.coreboot.org/c/flashrom/+/62894 ) Change subject: ichspi: Rename HSFC_FDBC -> HSFC_FDBC_MASK ...................................................................... Patch Set 6: (1 comment) File ichspi.c: https://review.coreboot.org/c/flashrom/+/62894/comment/30bdad5c_602e61f6 PS4, Line 508: FDBC > `HSFC_FDBC_MASK` exists but there is no macro to resolve this symbol `HSFC_FDBC_MASK_OFF` So, just very straightforward thought: if you also rename HSFC_FDBC_OFF into HSFC_FDBC_MASK_OFF then naming complies with existing pprint_reg() design? and there will be no need for _pprint_reg() ? Not sure whether this straightforward idea is the most correct. It seems like a good idea to have only one print macro: then there is no question which one to use, and how to use. But I am not sure how much work it is. I can see that renaming HSFC_FDBC -> HSFC_FDBC_MASK plays a role further in the chain in CB:62892 so "do nothing" is not an option as it blocks further work. That's why I thought, if getting rid of _pprint_reg() is too much (for whatever reason) then maybe renaming both HSFC_FDBC -> HSFC_FDBC_MASK and HSFC_FDBC_OFF -> HSFC_FDBC_MASK_OFF can be okay? And it can be a temp step on the way to getting rid of _pprint_reg() later. -- To view, visit https://review.coreboot.org/c/flashrom/+/62894 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: Ia0ae9a586b5c12f0229334898426175ec246a70c Gerrit-Change-Number: 62894 Gerrit-PatchSet: 6 Gerrit-Owner: Subrata Banik <subratabanik(a)google.com> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Reviewer: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-CC: Subrata Banik <subi.banik(a)gmail.com> Gerrit-Attention: Subrata Banik <subi.banik(a)gmail.com> Gerrit-Attention: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Subrata Banik <subratabanik(a)google.com> Gerrit-Attention: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Comment-Date: Wed, 06 Apr 2022 06:41:03 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Subrata Banik <subi.banik(a)gmail.com> Comment-In-Reply-To: Nico Huber <nico.h(a)gmx.de> Comment-In-Reply-To: Subrata Banik <subratabanik(a)google.com> Comment-In-Reply-To: Angel Pons <th3fanbus(a)gmail.com> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-MessageType: comment
