Subject: [PATCH BUG 0/2] rpi: Fix PXE issues with grub

When PXE booting with grub the network link isn't given a chance to resume
so grub's transmit calls fail. This results in failed boots. Similarly the DMA
range for the adapter isn't right since it doesn't have a 32-bit restriction.
Again this keeps grub from failing on 8G devices,
