Done. BTW - I wonder if we should change most of these `if (ich_generation == ...)` statements to `switch (ich_generation)`. That would solve any indentation issue now and moving forward, and would also be more uniform with other parts of the ichspi and ich_desctriptors code that have to deal with multiple generations. https://review.coreboot.org/#/c/20922/2/ichspi.c@1703 PS2, Line 1703: num_freg = 12; /* 12 MMIO regs, but 16 regions in FD spec */ > 10 is correct, the registers read with 0x00007fff just what is set So should we leave it at 12 to match the datasheet, even though FREG10 and 11 read 0 and are ignored? Should we explain this behavior in the comment? LMK your thoughts on how to proceed from here. https://review.coreboot.org/#/c/20922/2/ichspi.c@1704 PS2, Line 1704: 6; /* Includes GPR0 */ > 6 including the GPR0 register, sorry should have added a comment... Ah, that makes sense. I went ahead and added a comment for Sunrise Point and Lewisburg. ICH8/9 don't have a GPR register, so 5 is already correct to account for PR0-PR4. -- To view, visit https://review.coreboot.org/20922 To unsubscribe, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: staging Gerrit-MessageType: comment Gerrit-Change-Id: I96c89bc28bdfcd953229c17679f2c28f8b874d0b Gerrit-Change-Number: 20922 Gerrit-PatchSet: 3 Gerrit-Owner: David Hendricks <david.hendricks(a)gmail.com> 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: Mon, 21 Aug 2017 04:41:32 +0000 Gerrit-HasComments: Yes

Hello Paul Menzel, build bot (Jenkins), Nico Huber, I'd like you to reexamine a change. Please visit https://review.coreboot.org/20922 to look at the new patch set (#3). Change subject: chispet_enable: Add support for C620-series Lewisburg PCH ...................................................................... chispet_enable: Add support for C620-series Lewisburg PCH This adds PCI IDs for C620-series PCHs and adds CHIPSET_C620_SERIES_LEWISBURG as a new entry in the ich_chipset enum. Lewisburg is very similar to Sunrise Point for Flashrom's purposes, however one important difference is the way the "number of masters" is interpreted from the flash descriptor (0-based vs. 1-based).
