[coreboot] Read the Coreboot version in the .rom binary

[Patrick Agrain]

Hello all,

Is there a way to read the coreboot version (as a string or as binary 
chain) from inside the build coreboot.rom file.

We wish to upgrade the binary in the flash ROM (by a userspace tool 
calling 'flashrom')  only when necessary.
Reading the flashed version can be made by a 'cat 
/sys/class/dmi/id/bios_version'.
What is missing is the version of the "new" binary to compare them.

Kind regards,
Patrick Agrain
