Patch Set 12: Code-Review+1 (2 comments) File dummyflasher.c: https://review.coreboot.org/c/flashrom/+/59074/comment/5c6359ec_9c40f4f3 PS10, Line 264: /* XXX: should data->erase_to_zero be taken into account here? */ > It does look like a bug to me, thanks! […] +1, preserving the current behavior with a FIXME comment is the best option IMO. File dummyflasher.c: https://review.coreboot.org/c/flashrom/+/59074/comment/52613586_ce3bec06 PS12, Line 236: if (start >= data->wp_start && start < data->wp_end) : return true; : : const uint32_t last = start + len - 1; : return (last >= data->wp_start && last < data->wp_end); These two tests can be combined as: const uint32_t last = start + len - 1; return (start < data->wp_end && last >= data->wp_start); Actually they need to combined to catch the theoretical case where the region being written strictly contains the protection region. Although that isn't an issue for now since most chips only have protection regions at one end of address space. -- To view, visit https://review.coreboot.org/c/flashrom/+/59074 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I9fd1417f941186391bd213bd355530143c8f04a0 Gerrit-Change-Number: 59074 Gerrit-PatchSet: 12 Gerrit-Owner: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Angel Pons <th3fanbus(a)gmail.com> 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: Maciej Pijanowski <maciej.pijanowski(a)3mdeb.com> 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: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Attention: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Comment-Date: Mon, 06 Dec 2021 09:52:51 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Comment-In-Reply-To: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-MessageType: comment

I think the main issues have been resolved now, so please let me know what you think about merging them or what other changes I should make. I've retested all operations with the latest patch series (list ranges, set range, enable, disable, status) with the GD25Q32/GD25LQ128/GD25Q256 chips and they work as expected. I haven't been able to retest on the GD25Q64/MX25L2006E/W25X40 chips yet, though I expect they will still work. I can either remove support for those chips for now or submit them as-is and retest when I get replacement chips. -- To view, visit https://review.coreboot.org/c/flashrom/+/58474 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I67e9b31f86465e5a8f7d3def637198671ee818a8 Gerrit-Change-Number: 58474 Gerrit-PatchSet: 11 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: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-Comment-Date: Mon, 06 Dec 2021 08:53:20 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment
