Anastasia Klimchuk has submitted this change. ( https://review.coreboot.org/c/flashrom/+/60230 ) Change subject: spi25_statusreg.c: add SR3 read/write support ...................................................................... spi25_statusreg.c: add SR3 read/write support Adds support for reading and writing the third status register. Feature flag is not needed because it would never on its own control whether SR3 access occurs. If added, it would be in one of three possible states: wrong, useless or redundant.

Change in flashrom[master]: flashchips: Add IS25WQ040

Attention is currently required from: Felix Singer, roman.stingler(a)gmail.com. Vasily Galkin has posted comments on this change. ( https://review.coreboot.org/c/flashrom/+/63910 ) Change subject: flashchips: Add IS25WQ040 ...................................................................... Patch Set 1: Code-Review-1 (1 comment) Patchset: PS1: I used flashrom to flash the IS25WQ040 and initially started with this patch. During flasing I found that the IC size in the patch is specified incorrectly. According to docs and in practice - it is 4096 KiBits, not 4096 KiBytes. So the size in this patch is specified in correctly. I'd fixed this, perform testing and created https://review.coreboot.org/c/flashrom/+/58179 (it is still not merged). Unfortunately I didn't crosslinked it form github, and this was created as a duplicate... So, I think that https://review.coreboot.org/c/flashrom/+/58179 should be merged instead of this, since here the size is incorrect. -- To view, visit https://review.coreboot.org/c/flashrom/+/63910 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I6f188e006bda415221c571c6aa9cfece649e572f Gerrit-Change-Number: 63910 Gerrit-PatchSet: 1 Gerrit-Owner: Felix Singer <felixsinger(a)posteo.net> Gerrit-Reviewer: Vasily Galkin Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Reviewer: roman.stingler(a)gmail.com Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Felix Singer <felixsinger(a)posteo.net> Gerrit-Attention: roman.stingler(a)gmail.com Gerrit-Comment-Date: Thu, 28 Apr 2022 13:36:39 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Gerrit-MessageType: comment

Change in flashrom[master]: dummyflasher: enforce write protection for W25Q128FV
by Sergii Dmytruk (Code Review) 28 Apr '22

28 Apr '22

Attention is currently required from: Nico Huber, Angel Pons, Sergii Dmytruk. Hello build bot (Jenkins), Nico Huber, Angel Pons, Nikolai Artemiev, Anastasia Klimchuk, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/59074 to look at the new patch set (#32). Change subject: dummyflasher: enforce write protection for W25Q128FV ...................................................................... dummyflasher: enforce write protection for W25Q128FV Start taking bits related to write protection into account. Also add "hwwp" parameter for dummy programmer that sets state of WP pin (not inverted value). dummyflasher doesn't store state of the chip between runs and flashrom allows running only one command, so testing WP in this way is limited. However, WP options can be combined with other operations and are executed prior to them, so certain scenarios can be checked. List possible ranges: flashrom -p dummy:emulate=W25Q128FV,hwwp=yes --wp-list Set a particular range and check status is correct: flashrom -p dummy:emulate=W25Q128FV,hwwp=yes \ --wp-enable \ --wp-range=0x00100000,0x00f00000 \ --wp-status Enable write protection and try erasing/writing (erasing here): # this fails flashrom -p dummy:emulate=W25Q128FV,hwwp=yes \ --wp-range=0,0x00c00000 \ --wp-enable \ --erase Write protecting empty range has no effect: # this succeeds flashrom -p dummy:emulate=W25Q128FV,hwwp=yes \ --wp-range=0,0 \ --wp-enable \ --erase Change-Id: I9fd1417f941186391bd213bd355530143c8f04a0 Signed-off-by: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> --- M dummyflasher.c M flashrom.8.tmpl 2 files changed, 157 insertions(+), 18 deletions(-) git pull ssh://review.coreboot.org:29418/flashrom refs/changes/74/59074/32 -- 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: 32 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: Sergii Dmytruk <sergii.dmytruk(a)3mdeb.com> Gerrit-MessageType: newpatchset
