Damien Zammit (damien(a)zamaudio.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10074 -gerrit commit cecc99e3312dc4e2bad2413515a07bd0a1b700f8 Author: Damien Zammit <damien(a)zamaudio.com> Date: Mon May 4 00:45:35 2015 +1000 mainboard/intel/d510mo: Add Intel D510MO mainboard Board currently has no raminit, (but uses Pineview minimal northbridge). Board boots to UART console.

New patch to review for coreboot: 639e25f drivers/spi/stmicro: Fixes for N25Q256
by David Imhoff 03 May '15

Removed the 'A' at the end of the product name. This only indicates the production process(64 nm), and is also left out for the other chips. Finally corrected page/sector sizes to be able to use the 'sub sector erase' command. Untested, due to lack of hardware.

Patch set updated for coreboot: f2a3a95 spi: Changed 'page' to 'sector' in log message
by David Imhoff 03 May '15

03 May '15

David Imhoff (dimhoff_devel(a)xs4all.nl) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/10067 -gerrit commit f2a3a954e4dc0a867ab4d84fc8ec5c2c6972e740 Author: David Imhoff <dimhoff_devel(a)xs4all.nl> Date: Sun May 3 13:47:49 2015 +0200 spi: Changed 'page' to 'sector' in log message The log message said 'page size' while actually the sector size was printed. This is confusing since for stmicro page size != sector size. Also added '0x' prefix to numbers to make it clear they are in hex.
