The only probing method supported by the Nvidia SN2201 platform driver
is probing through an ACPI match table. Hence add a dependency on
ACPI, to prevent asking the user about this driver when configuring a
kernel without ACPI support.

|
serial port (RS-232 interface), an OOB port (1G/100M MDI interface)
|
|
and USB ports for management functions.
|
|
The processor used on SN2201 is Intel Atom®Processor C Series,
|
|
C3338R which is one of the Denverton product families.
|
|
System equipped with Nvidia®Spectrum-1 32x100GbE Ethernet switch.
