Subject: Status of aspeed-bmc-opp-firestone (IBM S822LC)

Dear Joel, dear Linux folks,

We have an IBM S822LC system (Firestone(?)). Building of OpenBMC 
currently fails, as the not everything was ported from dev-4.10 to 
dev-4.13 [1], and therefore a file cannot be found.

Looking at upstream Linux, there are BMCs for Power 8 systems, like 
Palmetto, included.

```
$ ls arch/arm/boot/dts/aspeed-bmc-opp-*
arch/arm/boot/dts/aspeed-bmc-opp-palmetto.dts
arch/arm/boot/dts/aspeed-bmc-opp-romulus.dts
arch/arm/boot/dts/aspeed-bmc-opp-witherspoon.dts
arch/arm/boot/dts/aspeed-bmc-opp-zaius.dts
```

Does somebody know, why Firestone was not upstreamed? Is somebody 
working on upstreaming it? If not, do you have scripts to port such 
work? Manually cherry-picking stuff in this case is hard, as there are a 
lot of conflicts.

Kind regards,

Paul
