Nico Huber has submitted this change and it was merged. ( https://review.coreboot.org/23338 ) Change subject: digilent_spi: add a driver for the iCEblink40 development board ...................................................................... digilent_spi: add a driver for the iCEblink40 development board This is driver that supports the Lattice iCE40 evaluation kits. On the board is a SPI flash memory chip labeled ST 25P10VP. Tested to work read/write/erase with "-p digilent_spi -c M25P10" or with a patch that resets the part beforehands (in which case it gets detected as a M25P10-A and is way faster due to paged writes).

Change in flashrom[master]: make args for -r/-w/-v non-positional and optional
by Nico Huber (Code Review) 24 Jun '18

24 Jun '18

Nico Huber has posted comments on this change. ( https://review.coreboot.org/23022 ) Change subject: make args for -r/-w/-v non-positional and optional ...................................................................... Patch Set 13: Code-Review+1 So here is a +1 for overall sanity of the implementation. I still don't like the syntax and non-positional argument story. And if we don't keep full compatibility, I'd rather start over with a stricter, more expli- cit and easier to parse syntax. But if the two of you want it in, go ahead. The manpage still seems to miss the fact that the filename argument is non-positional btw. -- To view, visit https://review.coreboot.org/23022 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: flashrom Gerrit-Branch: master Gerrit-MessageType: comment Gerrit-Change-Id: Iefbcb7dc4fefe26f5afd1292dfd5c1687fa62803 Gerrit-Change-Number: 23022 Gerrit-PatchSet: 13 Gerrit-Owner: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Arthur Heymans <arthur(a)aheymans.xyz> Gerrit-Reviewer: David Hendricks <david.hendricks(a)gmail.com> Gerrit-Reviewer: Louis Yung-Chieh Lo <yjlou(a)chromium.org> 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, 24 Jun 2018 18:11:24 +0000 Gerrit-HasComments: No Gerrit-HasLabels: Yes
