[coreboot] coreboot and linuxboot

[Jorge Fernandez Monteagudo]

Hi all,

I've built a coreboot with the LinuxBoot payload. The kernel is the stable 5.3.8 version and the intiramfs is the u-root master version.
All with the default choices. I'm using coreboot 4.10.

Once the system boots I get a framebuffer console without usb keyboard support and the u-root welcome message.
How can I boot my debian system on a SATA or a USB disk? Maybe, first I've to add SATA and usb storage support?
Is there someway to looks for the grub configuration automatically?

Sorry my noob questions, just arrived to LinuxBoot...

Thanks!
Jorge
