Boot time of coreboot on MSM800SEV

[Piotr Piwko]

Hello,

I set about to build and implement the coreboot bios on my MSM800SEV
(LX800) platform from Digital Logic. In order to do that I would like
to know how much time it takes to boot a bootloader (ex. GRUB)? Have
you ever measured this factor on MSM800SEV platform? It will be nice
if you can provide my an estimated time.

Thank you in advance for engagement.

Not on that exact platform, as far as I know.

Recently Kevin O'Connor made some measurements on a VIA C7 based
board, and came to a point where power sequencing on the mainboard
was more than 50% of the time from power on to bootloader, IIRC he
reached 450ms.

I have measured slightly longer time, about 600ms, on another Geode
LX800 board (ALIX.1C) which might be explained by the fact that Geode
requires more initialization than C7.

In any case, it should be less than one second.

So, I'm going to be the first one :)

Excellently!

Thank you for quick answer.
