bari, hi, thank you for joining.  allow me to pick up on one thing
here - the M3 EC stuff.

 _wowww_ i just looked these up, and... what do you know about these:

 and... yaay!

 ok so.... that looks... damn good!  some of them even have DACs,
PWMs, USB, SDIO and so on.  so, not only could it do power management,
gpio and so on, but also it could act as the SD/MMC card reader, the
Mic / Speaker Audio IC,

 so what's the deal with coreboot?  what's the link there?  i'm just
asking, because if the overall design is to use an ARM Cortex A9
embedded CPU as the main processor, and say these STM32s for the I/O
handling, i'm not entiiirely certain where coreboot would come in to
that :)

p.s. just talking on irc to some guy, he has a 72mhz STM32 he's
managed to "overclock" to 128mhz -
