SubjectRe: [PATCH 3/3] ghes_edac: add platform check to enable ghes_edac
(Sending to your other mail address because there's some temporary resolution
issue:

msmtp: recipient address mchehab@s-opensource.com not accepted by the server
msmtp: server message: 451 4.3.0 <mchehab@s-opensource.com>: Temporary lookup failure
msmtp: could not send mail (account alien8.de from /home/boris/.msmtprc)

Maybe the problem is on my end.)

Right, let's hope.

Or maybe edac=try_FF or so. But yeah, I guess we'll need something to
tell the EDAC core to try FF first.

So I don't want to break existing users and thus make only explicitly
known platforms load ghes_edac. In the current case, the HPE machines.
All the rest will simply use the platform drivers and nothing will
change for them.

Later we'll probably need to revisit this decision but right now and
with all things considered, the whitelist seems - as ugly as it is - the
most workable solution for all the different use cases and machines...
