Subject: [PATCH] net: sun8i-emac: fix endianness issues

The network MAC in recent Allwinner SoCs uses an internal DMA controller,
which gets its information from DMA descriptors in normal memory.
The device expects the values in there to be in little-endian format.
Since we use normal memory accesses to fill those DMA descriptors, we
must wrap write accesses to these descriptors with cpu_to_le32() calls

Subject: [PATCH] sunxi: add SPL FEL button

Some of the newer Allwinner boards that come with SPI flash soldered
are missing an easy way to trigger the USB-OTG FEL boot mode.
On most boards without eMMC FEL mode is entered when there is no SD card
found, boards with eMMC typically feature a hardware FEL button.
Now some boards like newer boards from OrangePi have no eMMC, but have a SPI
