Intel Galileo - Gen 2 - SPI rom and bricked units

The SPI flash chip is a Winbond 25Q64FV. This is a 64 Mbit (8 Mbyte) flash. This is a serial NOR flash.

I have not yet bricked my unit, and hope I never do. The procedures for recovery are interesting and instructive in any event though, so here are some links.

Note that the SF-100 Dediprog is a $300 item. If it came to needing one of these, most folks would just toss a $45 Galileo, sad as that might be. However, it is possible to use a Bus-pirate (and I already have one in my toolkit). All that is required then is the proper cable.

Reflashing and the BSP

Go here to find the BSP sources mentioned in the reversatronics page: Note that the BSP sources are shipped in some insane 7z format. On Fedora you install the p7zip package, then run "7za" to extract files. (What could be more ill-conceived and stupid?) This yields: 
mkdir sources
cd sources
7za x ../Board_Support_Package_Sources_for_Intel_Quark_v1.0.1.7z
-rw-rw-r-- 1 tom tom  192465 May 22  2014 grub-legacy_5775f32a+v1.0.1.tar.gz

-rw-rw-r-- 1 tom tom    9876 May 22  2014 sysimage_v1.0.1.tar.gz
But this may all be old history. The PDAT file mentioned above is nowhere to be found, and besides -- there is a newer bundle (without the 7z nonsense), namely: BSP_Sources_and_Docs_for_Intel_Quark_v1.2.1.1.zip 
mkdir sources
cd sources
unzip ../BSP_Sources_and_Docs_for_Intel_Quark_v1.2.1.1.zip
