[S] Change in flashrom[master]: fmap: ignore areas with zero size
by Thomas Heijligen (Code Review) 14 Mar '23

14 Mar '23

Thomas Heijligen has submitted this change. ( https://review.coreboot.org/c/flashrom/+/73571 ) Change subject: fmap: ignore areas with zero size ...................................................................... fmap: ignore areas with zero size It's impossible for flashrom_layout to represent zero-sized flash regions but it is possible for a fmap to contain a zero-sized region which causes the resulting layout to fail layout_sanity_checks(), preventing use of that fmap. Because it would very rarely make sense to be able to operate on zero-sized regions anyway and changing layouts to be able to support zero-size regions would entail large changes, instead ignore zero-size regions when present in fmap. TEST=Warning is now printed when using fmap that contains a zero-sized area, and operations on other regions are allowed to proceed.

When removing the `rpci_` functions and using proper shutdown functions there is no need to have `pacc` globally accessible any longer. -- To view, visit https://review.coreboot.org/c/flashrom/+/73570 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: Id2983420080f75ae6992edfb032bf5c83b29c803 Gerrit-Change-Number: 73570 Gerrit-PatchSet: 4 Gerrit-Owner: Thomas Heijligen <src(a)posteo.de> Gerrit-Reviewer: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-Reviewer: Edward O'Callaghan <quasisec(a)chromium.org> Gerrit-Reviewer: Thomas Heijligen <src(a)posteo.de> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Comment-Date: Tue, 14 Mar 2023 10:22:21 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Comment-In-Reply-To: Edward O'Callaghan <quasisec(a)chromium.org> Comment-In-Reply-To: Anastasia Klimchuk <aklm(a)chromium.org> Gerrit-MessageType: comment

Revert "pcidev: remove pcidev_getdevfn() function" As Edward pointed out correctly this function does more than abstracting the different versions of `pci_get_dev()`. It also hide the usage of the global `struct pci_access pacc` from the caller. This reverts commit 0e8902f1ff2b927bb91a5e89e4fde3d8d71f6692.
