Patch Set 1: (2 comments) https://review.coreboot.org/#/c/20937/1//COMMIT_MSG Commit Message: https://review.coreboot.org/#/c/20937/1//COMMIT_MSG@9 PS1, Line 9: The "number of masters" (NM) reflects the value that begins at 1. Seems that this is right for Lewisburg, awesome! more mess for us to handle. I've never found a definition if it starts at 0 or 1 and past practice was to count from 0 (== 1 master)! All descriptors in the wild that I've encountered were for platforms with 3 masters and always had NM set to 2 ;) Now the SPI guide for Lewisburg states it should be 6 (and there are only 6 masters mentioned), hmmm. I guess the lack of an explicit definition confused Intel's developers even more than us and now they disagree. No prob- lem for them, as they make one (binary) program for each platform anyway (I suppose). Two solutions come to mind: Take the guessed platform into account (Lewisburg would need its own constant). Or we could ignore a too high NM and just return MAX_NUM_MASTERS (and drop a lot of sanity checks as we could return an unsigned value). https://review.coreboot.org/#/c/20937/1//COMMIT_MSG@17 PS1, Line 17: even more wrong than it was before. I don't see any loop doing it wrong, nor any caller adding 1 to the return value. -- To view, visit https://review.coreboot.org/20937 To unsubscribe, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: staging Gerrit-MessageType: comment Gerrit-Change-Id: I92627332265cf79720b98241d73bc36b1f6a7167 Gerrit-Change-Number: 20937 Gerrit-PatchSet: 1 Gerrit-Owner: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: Paul Menzel <paulepanter(a)users.sourceforge.net> Gerrit-Reviewer: Stefan Tauner <stefan.tauner(a)gmx.at> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Comment-Date: Thu, 10 Aug 2017 11:55:24 +0000 Gerrit-HasComments: Yes

David Hendricks has uploaded this change for review. ( https://review.coreboot.org/20937 Change subject: ich_descriptors: Fix off-by-one error ...................................................................... ich_descriptors: Fix off-by-one error The "number of masters" (NM) reflects the value that begins at 1. This value is compared with the constant MAX_NUM_MASTERS, which also begins with 1. So we really do want the raw value of NM to be used in the comparison. This fixes problems that arise when the actual NM value and MAX_NUM_MASTERS are equal. Also, the return value then gets used as an upper limit for for loops with counters beginning at 0. So adding 1 to the return value makes it even more wrong than it was before.
