[U-Boot] [PATCH v2 0/5] ARM: Allwinner sun7i (A20) USB Host EHCI support

[Roman Byshko]

This patch series adds USB Host EHCI support to the sun7i SoC. It was
tested on Cubietruck. Now you could boot from a USB stick or use a
compatible Ethernet dongle to add a second Ethernet port in U-Boot.

ehci-sunxi.c contains some code for poking GPIOs. This code will go
away once [1] is applied against upstream. For now this patch series is
self-contained and has no dependencies.

Best,
Roman Byshko

Changes since v1:
	- fixed erroneous copyright author
	- used SPDX tag instead of the full license
	- used setbits_le32/clrbits_le32 instead of direct bit poking
	- usage of setbits_le32/clrbits_le32 automatically fixed bug
	  where usbc_bit was clobbered unintentionally
	- added more info about commented out gpio_direction_output, it
	  will be used once [1] is applied against upstream
