ConnectCore 6 Linux BSP Reference Manual

.
Wireless
The module assembles an Atheros wireless chip connected to uSDHC1.
The MAC address is taken from U-Boot environment variable
wlanaddr
which is populated by U-
Boot on the Device Tree before booting Linux.
There is no generic Device Tree binding for the Bluetooth interface. Digi has created a wireless
entry node to pass the driver the MAC address (filled-in by U-Boot) and the power down GPIO:

}
