[coreboot] Apollolake: SATA issues

[Christian Gmeiner]

Hi all

I have ported coreboot to a custom design based on APL and have random
SATA problems with CFast cards. I am using the latest public APL FSP
from github with the latest coreboot master.

From time to time the SATA link 'dies' during runtime or I it is not
possible to establish the SATA link at all (in the used u-boot
payload). At the moment I am running out of ideas and I hope someone
can point me in the right direction.

Btw. with the vendor blob SATA works with out any problems :/
