[U-Boot] [PATCH v3 0/5] ARM: Allwinner sunxi USB Host EHCI support

[Roman Byshko]

This patch series adds USB Host EHCI support to the sunxi SoCs. 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.

Best,
Roman Byshko

Changes since v2:
	- improved commit messages
	- removed BIT macro
	- added get_io_base function
	- removed unnecessary verboseness when defining sunxi_echi_hcd
	  array
	- the EHCI driver is now based on [2] and uses GPIO driver 
	- possible failure is ruled out by introducing enabled_hcd_count
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
