So uh, what exactly does this patchset do ? It's not clear at all from the
subject and any description is completely missing.
To my knowledge, i.MX6 already does have USB support in U-Boot, so the subject
is misleading as well.
mx6sxsasbresd board and mx6slevk board does not have board level support
for usb. This patchset is mainly to add pinmux and implement
board_ehci_hcd_init and board_echi_power and add USB CONFIG in header
file to make usb work fine.
I'll send another patch for review, if "usb:ehci-mx6 add
board_ehci_usb_mode function" is fine.
Changes v2:
- move pinmux setting into board_init
- add otg polarity setting in board_ehci_hcd_init
- Introduce a new weak function to give board a choice to decide the work
mode of the otg port, since a otg port can also work in host mode without
touch ID pin.

usb:ehci-mx6 add board_ehci_usb_mode function
imx:mx6sxsabresd add usb support
imx:mx6slevk add usb support
