Change in flashrom[master]: Add Elkhart Lake support

25 Jan '22

Attention is currently required from: Nico Huber. Hello build bot (Jenkins), Nico Huber, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/60711 to look at the new patch set (#3). Change subject: Add Elkhart Lake support ...................................................................... Add Elkhart Lake support Elkhart Lake has a chipset called Mule Creek Canyon which is quite compatible with 300 series chipsets. There are a few differences though, e.g. different encoding for the SPI clock values for read and write in the FLCOMP register. In addition Elkhart Lake has a new PCI device ID for the SPI controller which is added, too.

Change in flashrom[master]: ich_descriptors.c Invert the meaning of 'dual_output' bit
by Werner Zeh (Code Review) 25 Jan '22

25 Jan '22

Hello build bot (Jenkins), Angel Pons, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/61362 to look at the new patch set (#2). Change subject: ich_descriptors.c Invert the meaning of 'dual_output' bit ...................................................................... ich_descriptors.c Invert the meaning of 'dual_output' bit In the Flash Component description register (FLCOMP) bit 30 reports the capability of using dual output for fast read operation on the flash component. According to various SPI Programming Guides (checked for Panther Point, Lewisburg C620, Apollo Lake and Elkhart Lake) the dual output is enabled when this bit is set and disabled if not. Currently the logic displays it the other way around when parsing the descriptor. This patch changes this so now if bit 30 in FLCOMP is not set, dual read support for fast read operation is shown as disabled.

Starting with "According to the SPI Programming Guide" makes it seem like you only checked one SPI programming guide. I'd suggest rephrasing the sentence as follows: According to the SPI Programming Guides for Panther Point, Lewisburg C620, Apollo Lake and Elkhart Lake, the dual output is enabled when this bit is set and disabled if not. Another option would be to move the part in parentheses closer to "SPI Programming Guide": According to various SPI Programming Guides (checked for Panther Point, Lewisburg C620, Apollo Lake and Elkhart Lake), the dual output is enabled when this bit is set and disabled if not. Patchset: PS1: I checked the SPI programming guides for Lynx Point, Wildcat Point, Bay Trail, Skylake-H and Gemini Lake; all agree with this change. -- To view, visit https://review.coreboot.org/c/flashrom/+/61362 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-Change-Id: If6282ac8326ab0b92e9c70c09dba0299bf0deb6f Gerrit-Change-Number: 61362 Gerrit-PatchSet: 1 Gerrit-Owner: Werner Zeh <werner.zeh(a)siemens.com> Gerrit-Reviewer: Angel Pons <th3fanbus(a)gmail.com> Gerrit-Reviewer: build bot (Jenkins) <no-reply(a)coreboot.org> Gerrit-CC: Paul Menzel <paulepanter(a)mailbox.org> Gerrit-Attention: Werner Zeh <werner.zeh(a)siemens.com> Gerrit-Comment-Date: Tue, 25 Jan 2022 10:15:49 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: Yes Gerrit-MessageType: comment
