[PATCH v2 0/9] ARM: add Microchip LAN9696 (LAN969X) SoC and EV23X71A board

[Oleksij Rempel]

This series adds barebox support for the Microchip LAN9696 (LAN969X
family) SoC and the EV23X71A evaluation board, a 28-port Ethernet switch
platform with an ARM64 Cortex-A53 and AT91/SAMA5 compatible peripherals.
barebox runs as BL33 in a TF-A boot chain.
