I was going through
http://www.fsf.org/blogs/community/welcome-to-libreplanet-2015 and came to know about libreboot free boot firmware. Just curious to know is firmware written in C? and how is it different from coreboot. it also says free replacement for BIOS/UEFI or are coreboot and libreboot both same. Libreboot is a de-blobbed version of Coreboot and i am not sure if i understand the meaning of de-blobbed.
