Hello build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/22344 to look at the new patch set (#2). Change subject: linux_spi: Dynamically detect max buffer size ...................................................................... linux_spi: Dynamically detect max buffer size The max buffer size of the linux kernel's SPI device is a compile-time parameter. Read it on initialization and use it to inform the max transfer size. We allow up to 5 bytes for the SPI command. SPI commands can be up to 5 bytes when using 4BA.

Change in flashrom[staging]: ichspi: Disable software sequencing by default for Skylake

David Hendricks has posted comments on this change. ( https://review.coreboot.org/22274 ) Change subject: ichspi: Disable software sequencing by default for Skylake ...................................................................... Patch Set 1: Code-Review+2 (1 comment) The Lewisburg datasheet seems to indicate that SCGO is RW, and I'm not aware of any C62x variants where that use a different datasheet. So I think we're safe there. However, I haven't tested swseq on Lewisburg since, as you suggested, I don't have one with an unlocked/non-zero opmenu at the moment. Flashrom sees the missing opcodes and falls back to hwseq on my test system. https://review.coreboot.org/#/c/22274/1/ichspi.c File ichspi.c: https://review.coreboot.org/#/c/22274/1/ichspi.c@1957 PS1, Line 1957: } Would it make sense to move this to line 1800, closer to where ich_spi_mode gets set (near the beginning of case CHIPSET_ICH8)? -- To view, visit https://review.coreboot.org/22274 To unsubscribe, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: staging Gerrit-MessageType: comment Gerrit-Change-Id: I8a13fb9c3ca679b3f7d39ad1dc56d5efdc80045b Gerrit-Change-Number: 22274 Gerrit-PatchSet: 1 Gerrit-Owner: Nico Huber <nico.h(a)gmx.de> Gerrit-Reviewer: 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: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-Comment-Date: Sun, 05 Nov 2017 01:51:34 +0000 Gerrit-HasComments: Yes
