[coreboot] Success in booting the kernel in less that 1 second on the x60

[Carl-Daniel Hailfinger]

Hi Charles,

the main talk deadline and lightning talk deadline for FOSDEM are over,
but maybe some of the developer rooms somewhat fit the topic and still
accept the talk? Not sure.

In any case, it would be great to have you there at FOSDEM at our booth
if we get a booth this year.

Regards,
Carl-Daniel
