[U-Boot] [PATCH 3/6] ARM: rmobile: Move HSUSB configuration to board on ULCB

[Nobuhiro Iwamatsu]

Hi,

2017-09-13 2:07 GMT+09:00 Marek Vasut <marek.vasut at gmail.com>:
> In order to use ehci-generic driver, move the configuration of HSUSB
> block into the board file. This configuration should not have been in
> the Gen3 EHCI USB driver in the first place, so move it to the board
> file until there is a proper infrastructure and driver for the HSUSB
> block.
