[edk2-devel] [edk2-platform][PATCH v1 6/6] Platform/RaspberryPi: set DMA translation for BCM Genet driver

[Samer El-Haj-Mahmoud]

From: Ard Biesheuvel <ard.biesheuvel at arm.com>

The driver for the Broadcom Genet network controller was modified
from a minimal MAC address programming driver to a true SNP driver
implementing full network functionality. Since this involve DMA,
set the DmaLib parameters correctly in the platform.
