[PATCH v2 0/2] arm64: meson-gxbb: NanoPi K2 enablement

[PATCH v2 0/2] arm64: meson-gxbb: NanoPi K2 enablement

[Andreas Färber]

Hello,

This mini-series adds initial support for the Amlogic S905 based
FriendlyARM NanoPi K2 SBC.

Tested with mainline U-Boot.

v2 adds USB and Wifi among others.

Regards,
Andreas
