[PATCH] arm: dts: aspeed: Enable PECI and LPC Snoop

[Andrew Jeffery]

Hi Manoj,

Can you please mention mentions the specific platform in the subject
(IBM System1)? Otherwise the single-line log view gives the impression
that you're enabling them for all Aspeed-based platforms.

Perhaps:

   ARM: dts: aspeed: Enable PECI and LPC snoop for IBM System1

Also, can you please send this to the upstream lists? From there I'll
backport it to the openbmc tree. `b4 prep --auto-to-cc` should help.

Andrew
