[coreboot] When does AMD release the fam15 spectre microcode updates?

[Taiidan at gmx.com]

They said they would be releasing opteron microcode updates in a few 
weeks but it has been over a month and I am wondering when this is going 
to happen or if it already has and I should re-compile coreboot?

"We expect to make updates available for our previous generation 
products over the coming weeks."

Thanks!
