Which is wrong. Darn! It felt a bit awkward since I also had to invert logic and a add set of parens. I tried to make this a bit more idiot-proof by breaking apart the if-statements for FLILL/FLILL1 and the chipset. This way we only need to check the chipset once, and it will make it easier to use a switch statement later if we want.

Change in flashrom[staging]: chipset_enable: Add support for C620-series Lewisburg PCH

by David Hendricks (Code Review)

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 (#5). Change subject: chipset_enable: Add support for C620-series Lewisburg PCH ...................................................................... chipset_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).
