[coreboot] [RFC] Proposal to move all FSP 1.x binaries to "legacy" branch

[Desimone, Nathaniel L]

Hi Everyone,

Given that the newest coreboot releases have not supported the FSP 1.x specification for years now, seems that the 1.x FSP binaries at https://github.com/intel/FSP have become increasingly limited in their usefulness. For this reason, I would like to move those older binaries off master branch and create a new “legacy” branch to store them. I'll be sure to mention the legacy branch in the readme.md file in master. Any concerns with this change?

Thanks,
Nate
