Change in flashrom[master]: internal.c: Fix map_flash() failures with linux_mtd via internal
by Edward O'Callaghan (Code Review) 11 Apr '22

11 Apr '22

Edward O'Callaghan has uploaded this change for review. ( https://review.coreboot.org/c/flashrom/+/63543 ) Change subject: internal.c: Fix map_flash() failures with linux_mtd via internal ...................................................................... internal.c: Fix map_flash() failures with linux_mtd via internal prepare_flash_access() calls into map_flash() however this can fail on some DUT's. The issue is that map_flash() can fail on opaque spi masters such as linux_mtd and even ichspi when they are dispatched into via 'internal'. The issue with 'internal' is that the hook 'map_flash_region = physmap' is used from the internal struct entry-point instance and not the native one for the underlying master. This fails on some board topologies such Volteer. Structually this is not easy to solve with how internal is currently implemented where it partially replaces itself with the underlying master and so this fix only addresses the case of linux_mtd.

Patch Set 2: (1 comment) Patchset: PS1: > Yes, that is correct. I just want to make sure we are not too pedantic […] While I can see the reasoning for this and it makes sense I have a supplementary argument to Nico's diff reduction maintenance one. I would rather we go the other way as by reducing both build system and pre-processor cyclomatic complexity means that the compiler is more likely to see a more consistent picture of the tree as the moving window of changes sweeps HEAD. Furthermore, it lets the linker in the toolchain do it's job and cull symbols that are not required in the resulting binary rather than trying to pre-optimise at the build system level. The associativity property should rather be done at the build target level to again, let the build system do its job of relationship management best. Hopefully my thinking makes sense here Thomas, however thanks for the different prospective too! -- To view, visit https://review.coreboot.org/c/flashrom/+/62832 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: I9a91c5801a573e7021686a183a1bd874122e35cc Gerrit-Change-Number: 62832 Gerrit-PatchSet: 2 Gerrit-Owner: Thomas Heijligen <src(a)posteo.de> Gerrit-Reviewer: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Reviewer: Felix Singer <felixsinger(a)posteo.net> Gerrit-Reviewer: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Nico Huber <nico.h(a)gmx.de> Gerrit-Attention: Thomas Heijligen <src(a)posteo.de> Gerrit-Comment-Date: Mon, 11 Apr 2022 04:49:12 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Nico Huber <nico.h(a)gmx.de> Comment-In-Reply-To: Thomas Heijligen <src(a)posteo.de> Gerrit-MessageType: comment
