The SN2201 enabling code is in drivers/platform, and it looks like it's an
architecture independent management device for server racks. See 662f24826f9.
Mellanox BlueField cards are specifically called out as "depends on ARM64",
and the fact that this driver doesn't have a similar dependency makes me
suspect it supports X86 and ARM64. But I could be wrong.
