[edk2-devel] [PATCH edk2-platforms v3 1/8] Platform/RaspberryPi4: set DMA translation for BCM Genet driver

[Ard Biesheuvel]

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