[Patch] Winbond W25Q64 support
by David Hendricks 24 Jun '10

24 Jun '10

This patch adds support for the W25Q64. It's similar, but has its own datasheet [Link<http://www.winbond.com.tw/hq/enu/ProductAndSales/ProductLines/FlashMemory/S…>], although it's mentioned in the W25Q{80,16,32} datasheet once. Anyway, I happen to have one and was able to successfully read, erase, and write to it using an NM10 based device. I was only able to successfully erase with D8h block erase and C7h chip erase commands, but other than that it seemed to work great. Patch attached.

[PATCH] Native DMI parser and cross checking with dmidecode
by Sean Nelson 24 Jun '10

24 Jun '10

The DMI Parser is based on dmidecode 2.10's dmidecode.c Stripped to bare minimums and only parses the System, Baseboard, and Chassis tables. Uses our physmap calls for hardware access. All of the cross-check code is contained in '#if 1' to easily find and shut off usage. Added my copyright line. Signed-off-by: Sean Nelson <audiohacked(a)gmail.com>

[Patch] add support for SiS963
by David Borg 24 Jun '10

24 Jun '10

Patch to enable sis963 southbridge and W83697HF/F SuperIO. DO NOT APPLY IT, as it needs to be finalised, (tomorrow probably). Please comment on what else needs to be done (which variables need to be initialised for example). Yes, it's a bit too verbose, but I'm still learning hehe. Probe works and detects the flash chip. Regards, David
