I think so: ThunderX and other server platforms should be more "standard" than small embedded boards. But if we decide to buy some small and cheap ARM32 boards, such as Linaro HiKey, they tend to still require special kernel trees. It is what you wish :). For instance Thunder-X support has been fully made upstream (ACPI + DT) only recently. In other words: I think we should be able to get rid of the special tree for the hardware that we have today, but I cannot guarantee that we won't ever need it in the future. IIRC we are going to get some renesas board recently. Do you know if upstream will work? Julien, do you think we need to keep a special linux tree around for Xen on ARM testing in OSSTest or we can start using vanilla kernel releases? I would love to get rid of it, if you know of any reasons why we have to keep it, this is the time to speak :-) I think it would be better to keep aroundSome platform may be available before the code is merged.

I think so: ThunderX and other server platforms should be more
"standard" than small embedded boards. But if we decide to buy so= me
small and cheap ARM32 boards, such as Linaro HiKey, they tend to still
require special kernel trees.
