Subject: [PATCH 4/4] arm64: avoid needing console= to enable serial console
Tell kernel to prefer one of the serial ports for console on
platforms currently supported (pl011 or 8250). console= on
command line will override these assumed preferences. This is
just a hack to get the behavior we want from DT provided by
firmware.

Subject: [PATCH 3/4] usb: make xhci platform driver use 64 bit or 32 bit DMA
The xhci platform driver needs to work on systems that either only
support 64-bit DMA or only support 32-bit DMA. Attempt to set a
coherent dma mask for 64-bit DMA, and attempt again with 32-bit
DMA if that fails.
