[coreboot] post_code to text file

[Haleigh Novak]

Thank you for the hint, I have 'installed' cbmem by making tthe appropriate menuconfig changes and in util/cbmem "$make LD_FLAGS=-static". Though (and I apologize for my nieve-ness) how exactly to I use the "$ cbmem -c" command, specifically wher exactly in boot/start up process should I call it- I cant call it from the OS, and I haven't been able to find anything on google relating to how to access coreboot userspace...

cbmem, in util/cbmem/, should be what you are looking for.
