How to suffix similar-but-different parts?
by David Hendricks 25 Jul '12

25 Jul '12

There's a SPI chip named "N25Q064" with 1.8V and 3V variants N25Q064A11 and N25Q064A13, respectively. The 1.8V has A11 suffixed, and the 3V version has A13 suffixed. The 'A' indicates the process technology which is likely to change without a change of device ID, so it's likely that we'll see something like N25Q064B11 or N25Q064B13 in the future. Fortunately, the two variants have different JEDEC IDs (0xBA17 and 0xBB17). So at least we can tell them apart via probing. stefanct and I were discussing how to name this chip couldn't really come up with a good solution. I am thinking that "N25Q064" is sufficient and that we should just re-use the same .name for two chip entries with different .voltage parameters.

Or rather (de)soldering would be necessary? the patch(es) and bucts are needed because the chipset is locked down by the vendor bios so much that vanilla flashrom can not cope with it (and modifying it so that it does is neither worth it nor trivial). please ask the coreboot guys about the details of the procedure. afaik desoldering is not necessary but an external programmer. if you already know the complete procedure please ask for a coreboot wiki account and create an article about it. it is recurring regularly here and on the coreboot ml (and obviously no one cares to document it fully). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Flashrom may well work if the boards do not require board specific enables but coreboot requires a specific port to each motherboard in question. So you are very likely to end up with a motherboard that will not boot. If you want to do the coreboot ports then the coreboot mailing list will be the place to get the help you need. Andrew

[PATCH] Intel QM77
by Wagner, Helge (GE Germany) 24 Jul '12

24 Jul '12

Hi all, Please find attached our changes for the QM77 chipset. I looked at the datasheet to be sure that the strap names (SPI, PCI, LPC) are the same as on the series 5 and 6 chipsets. Signed-off-by: Helge Wagner <Helge.Wagner(a)ge.com> Best Regards, Helge Wagner
