11 mraa has only been tested with 64 bit firmware version 0.73 or later.
15 The low speed I/O connector supported as per table below.
16 This assumes default BIOS settings, as they are not dynamcially detected
17 If any changes are mode (Device Manager -> System Setup -> South Cluster -> LPSS & CSS)
18 them mraa calls will not behave as expected.
20 Documentation shows i2c on bus #5, ACPI shows it on bus #6, but driver uses bus #7.
22 **SPI operation is not currently supported**
