[coreboot] your preferred method for supplying power to chip for RPi spi flashing?

[Michael Carbone]

Hi coreboot list,

I have been attempting to use a raspberry pi for spi flashing and when I
use the 3.3v pin the raspberry pi doesn't power up as the chip draws too
much power through the 3.3v pin for the raspberry pi to also run. I am
powering the RPi through micro-USB, either connected to wall outlet or
another computer.

What is your recommended method for powering the chip and RPi?

Looking online [1] some folks recommend using laptop AC adapter +
wake-on-lan (and not using the VCC/3.3v pin), but I'm not sure that's a
dependable strategy because I don't know if coreboot has WoL
functionality for the x230 should I want to reflash the chip [2].

Advice/thoughts appreciated, and let me know if there's a better place
to ask this question.

FYI this is the chip I am trying to program: [3]

Thanks,
Michael
