The comment says only wait for initial 100ms if the register is SR1. At line 74 initial 100ms already done. Why does `i` value matter at all? The loop is expected to have only one iteration for SR1? So just to be clear, my confusion is: why `i` value is modified, from reading the comment it seems like it doesn't matter in this case? -- To view, visit https://review.coreboot.org/c/flashrom/+/58475 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I0a3951bbf993f2d8d830143b29d3ce16cc6901d7 Gerrit-Change-Number: 58475 Gerrit-PatchSet: 20 Gerrit-Owner: Nikolai Artemiev <nartemiev(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: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Comment-Date: Tue, 01 Feb 2022 06:42:51 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Gerrit-MessageType: comment

Change in flashrom[master]: ichspi: Split very long init function into two

Patch Set 8: (3 comments) Patchset: PS7: > Thank you so much Nicolas for help! Nicolas, sorry for delay, I uploaded new version which (hopefully) fixes ich_spibar and ich_generation initialisation. Is it possible for you to try run it again on your machine? Thank you so much! PS7: > My memory tries to tell me something... back in 2012 we were […] Wow this is a very special computer that you found! ;) Does it still work? 10 years ago... this is impressive! Maybe you can keep it as a memory even if it doesn't work anymore :) If it still works... maybe you can keep it to test things sometimes?

I guess we […] Thank you so much for your analysis! This is helpful. ich_spibar is used in program_opcodes ichspi.c#L566, which is called at some point of init (as I understand?), and ich_generation is needed for run_opcode ichspi.c#L1081 ? I missed this :( global state makes it hard to understand what is used where, I am hoping to remove global state one day. I moved initialisation of both ich_spibar and ich_generation back into entry point ich_init_spi. This last patchset I tested on the device that I have, and now of course it needs to be tested on ICH7. The question that I have in mind: does the code looks good enough to re-test it again? At the moment I have no way to run init_ich7_spi code, so I only know that the code builds. -- To view, visit https://review.coreboot.org/c/flashrom/+/58735 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I6789bc456a4878e6555831ae0b80ecbdbf62938b Gerrit-Change-Number: 58735 Gerrit-PatchSet: 8 Gerrit-Owner: Anastasia Klimchuk <aklm(a)chromium.org> 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: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Felix Singer <felixsinger(a)posteo.net> Gerrit-CC: Nicholas Chin <nic.c3.14(a)gmail.com> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Felix Singer <felixsinger(a)posteo.net> Gerrit-Attention: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Attention: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Attention: Nikolai Artemiev <nartemiev(a)google.com> Gerrit-Attention: Nicholas Chin <nic.c3.14(a)gmail.com> Gerrit-Comment-Date: Tue, 01 Feb 2022 06:19:58 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Nico Huber <nico.h(a)gmx.de> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Comment-In-Reply-To: Nicholas Chin <nic.c3.14(a)gmail.com> Gerrit-MessageType: comment

Change in flashrom[master]: ichspi: Split very long init function into two
by Anastasia Klimchuk (Code Review) Jan. 31, 2022

Jan. 31, 2022

Attention is currently required from: Felix Singer, Edward O'Callaghan, Angel Pons, Anastasia Klimchuk, Nikolai Artemiev, Nicholas Chin. Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Nikolai Artemiev, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/58735 to look at the new patch set (#8). Change subject: ichspi: Split very long init function into two ...................................................................... ichspi: Split very long init function into two ich_init_spi is very long, but logically it can be split. Init function detects the chipset and then the rest of operations depends on the chipset. Init function is more readable now, it consists of only a switch. Initialisation of hwseq and swseq that used to happen in the beginning of init function now moved to init_ich_default, because hwseq and swseq are only used for chipsets served by init_ich_default.

Change in flashrom[master]: ichspi: Extract initialisation of swseq and hwseq into a function

Please visit https://review.coreboot.org/c/flashrom/+/58737 to look at the new patch set (#9). Change subject: ichspi: Extract initialisation of swseq and hwseq into a function ...................................................................... ichspi: Extract initialisation of swseq and hwseq into a function Initialisation of swseq_data and hwseq_data gets its own function, which is called from init_ich_default. This makes init_ich_default more readable. This patch also gives a name to (previously anonymous) struct swseq_data. Its sibling struct hwseq_data already has a name. Structs need names to be able to declare function parameters.
