Final calls for S3 suspend support on amdfam10-15

[Kyösti Mälkki]

Hi

The decisions are out on 4.11 release requirements. Unless anyone acts
on it, amdfam10-15 boards will hit deprecation due to:
* RELOCATABLE_RAMSTAGE=n
* CAR_GLOBAL_MIGRATION=y
* C_ENVIRONMENT_BOOTBLOCK=n

To smooth down the path, should anyone want to attempt on fixing
these, I have pushed a patchset [1] that removes S3 suspend support
from said platform. Depending of what the response is, I hope to have
that submitted already before 4.11 release.

The latest info [2] I have is asus/kcma-d8 not working and
asus/kgpe-d16 working in 4.6 but very slowly, for S3 resume boot, that
is. No resume logs have been brought to my knowledge for 12 months. I
also had some suspicions that tests results were mistakenly from
suspend-to-disk (S4).

Affected boards are asus/kcma-d8 and asus/kgpe-d16.
