Change in flashrom[master]: SFDP: make mandatory table length check work with newer SFDP revisions
by Nico Huber (Code Review) 26 Jan '22

26 Jan '22

Nico Huber has submitted this change. ( https://review.coreboot.org/c/flashrom/+/60055 ) Change subject: SFDP: make mandatory table length check work with newer SFDP revisions ...................................................................... SFDP: make mandatory table length check work with newer SFDP revisions The JEDEC SFDP specification JESD216A (1.5) adds five new DWORDs to the Basic Flash Parameter Table. Later versions of the spec add even more fields. This increases the table being read from 36 bytes to currently 64 bytes and makes flashrom bail out for any SFDP version >= 1.5 due to a static table length check. This was discovered on a GigaDevice GD25B127DSIGR from 2021 with SFDP revision 1.6, while another flash of the same model from 2020 with SFDP revision 1.0 was detected fine by flashrom. GD25B127DSIGR - 2020 version: Probing for Unknown SFDP-capable chip, 0 kB: SFDP revision = 1.0 SFDP number of parameter headers is 2 (NPH = 1). SFDP parameter table header 0/1: ID 0x00, version 1.0 Length 36 B, Parameter Table Pointer 0x000030 GD25B127DSIGR - 2021 version: Probing for Unknown SFDP-capable chip, 0 kB: SFDP revision = 1.6 SFDP number of parameter headers is 2 (NPH = 1). SFDP parameter table header 0/1: ID 0x00, version 1.6 Length 64 B, Parameter Table Pointer 0x000030 ... Length of the mandatory JEDEC SFDP parameter table is wrong (64 B), skipping it. The specification says that changes of the minor SFDP revision will maintain compatibility. Thus, simply check for the minimal required table length, which is 16 bytes for legacy Intel pre-SFDP and 36 bytes for SFDP.

Change in flashrom[master]: Add mediatek_i2c_spi interface
by Nico Huber (Code Review) 26 Jan '22

26 Jan '22

Attention is currently required from: Edward O'Callaghan, Angel Pons, Neill Corlett. Nico Huber has posted comments on this change. ( https://review.coreboot.org/c/flashrom/+/61288 ) Change subject: Add mediatek_i2c_spi interface ...................................................................... Patch Set 2: (2 comments) Patchset: PS1: > - We had two different board designs, one of which connects the TSUM* to SMBus and the other to raw I2C. This driver is tested on both. The finished product will be using I2C. I've left the SMBus code in as a convenience so we can continue to flash our earlier prototypes. Ah, hmmm, I'm not sure but I think there are SMBus controller drivers that could still advertise I2C_FUNC_I2C. Can you please confirm that this is not the case. Or can you tell us what controller is used specifically? Also, is the chip aware if it is connected over SMBus or I2C, e.g. by a pin strap? > - GPIO numbers are specific to TSUMOP82JUQ. My understanding is that these particular GPIO lines, for that chip, are standard for connecting to SPI WP#. Documentation that we received from PanVision just says to poke them and doesn't provide further detail. Who is PanVision in this story? Did they acquire the MSTAR chip line and provide the chips? or do they provide the board? or ...? Also, where do you use these chips, integrated display or something external? If you used SMBus, is it even on the mainboard? File mediatek_i2c_spi.c: https://review.coreboot.org/c/flashrom/+/61288/comment/e2d50ac8_de21b96a PS1, Line 96: args.data->block > I imagine Edward would like to avoid pointer arithmetics, substituting `args. […] I would use `args.data->block + 1` when targeting an array and `&args.data->block[1]` only if I target a single member. -- To view, visit https://review.coreboot.org/c/flashrom/+/61288 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I24adb14e7b4f7160e1c3ff941774064d5a81e820 Gerrit-Change-Number: 61288 Gerrit-PatchSet: 2 Gerrit-Owner: Neill Corlett <corlett(a)google.com> Gerrit-Reviewer: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Reviewer: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-CC: Peter Marheine <pmarheine(a)chromium.org> Gerrit-Attention: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Attention: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Attention: Neill Corlett <corlett(a)google.com> Gerrit-Comment-Date: Wed, 26 Jan 2022 15:18:17 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Nico Huber <nico.h(a)gmx.de> Comment-In-Reply-To: Edward O'Callaghan <quasisec(a)chromium.org> Comment-In-Reply-To: Angel Pons <th3fanbus(a)gmail.com> Comment-In-Reply-To: Neill Corlett <corlett(a)google.com> Gerrit-MessageType: comment
