[Paul Menzel]

Dear coreboot folks,

Kamyl pushed the board status for the Lenovo 430s, and I am excited
looking at the time stamps! Gone in 260 ms! Awesome.

So a big thank you to everyone involved in making that possible.
phcoder, the Googlers, siro, lynxis, and many, many more. This is great
work!

Thanks,

Paul

PS: Even the SMBIOS tables contain the embedded controller strings,
which takes over 100 ms on the Lenovo X60 for example.
