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
