DESCRIPTION:In essentially every PC\, the SPI flash chip package itself pro
 vides a relatively standardized interface to the SPI bus over which firmwa
 re is loaded and reprogrammed - if you've ever used a Pomona clip\, this i
 s exactly what they do. Flashkeeper is a system of add-on hardware\, desig
 ned around the "chip adapter" -  a flexible PCB designed to install perman
 ently on top of the SPI flash chip itself. Simple variants provide functio
 nality such as SPI bus breakout (useful in development whenever SPI flash 
 is hard to access)\, or standard SPI flash write protection control (pictu
 red). Another variant places an iCE40 FPGA on the chip adapter\, allowing 
 authenticated external flashing and vendor-agnostic runtime flash image ve
 rification (i.e. without requiring Boot Guard or similar). Unlike vendor-p
 rovided firmware verification tools\, the Flashkeeper FPGA module is an op
 en-hardware general-purpose computer under user control\, and is designed\
 , built and configured using an entirely open toolchain - this allows all 
 functionality to be extended and customized by the user.
