Change in coreboot[master]: lib: Add FIT payload support
by Julius Werner (Code Review) 05 Aug '19

Julius Werner has posted comments on this change. ( https://review.coreboot.org/c/coreboot/+/25019 ) Change subject: lib: Add FIT payload support ...................................................................... Patch Set 37: (1 comment) https://review.coreboot.org/c/coreboot/+/25019/37/src/lib/fit_payload.c File src/lib/fit_payload.c: https://review.coreboot.org/c/coreboot/+/25019/37/src/lib/fit_payload.c@45 PS37, Line 45: * Returns true on error, false on success. > Patrick, This was just pointed out in another commit. […] Do we have a hard and fast rule about how to do this? There are plenty of C functions where a 0 return code means success and non-zero means error (e.g. strcmp()), I assumed this was done in that spirit. (I think some guidelines suggest a pattern where functions that represent an action like extract() return 0 on success and non-zero on error, whereas functions that check if something is the case like islower() return the truth value of the check... but it's not widely standardized among C programmers.) Anyway, I'm fine with flipping it either way here, just saying that I can see arguments made in favor of both versions. (That's why I kinda dislike a bool return type for functions like this in general... if it's int, people would more commonly expect the 0-means-success pattern.) -- To view, visit https://review.coreboot.org/c/coreboot/+/25019 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-Change-Id: I0f27b92a5e074966f893399eb401eb97d784850d Gerrit-Change-Number: 25019 Gerrit-PatchSet: 37 Gerrit-Owner: Patrick Rudolph <patrick.rudolph(a)9elements.com> Gerrit-Reviewer: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Julius Werner <jwerner(a)chromium.org> Gerrit-Reviewer: Patrick Rudolph <patrick.rudolph(a)9elements.com> Gerrit-Reviewer: Paul Menzel <paulepanter(a)users.sourceforge.net> Gerrit-Reviewer: Philipp Deppenwiese <zaolin.daisuki(a)gmail.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Aaron Durbin <adurbin(a)chromium.org> Gerrit-CC: Martin Roth <martinroth(a)google.com> Gerrit-CC: Nico Huber <nico.h(a)gmx.de> Gerrit-CC: Patrick Rudolph Gerrit-Comment-Date: Mon, 05 Aug 2019 18:31:45 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Martin Roth <martinroth(a)google.com> Gerrit-MessageType: comment

On some devices, this causes MRC cache corruption and a bricked device. Fix this by removing the condition on CONFIG_DISPLAY_HOBS. Test: boot google/{cyan,edgar}, observe third boot and onward do not brick device, properly use mrc_hob via cbmem console and timestamps.
