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
