It would be good if it tested with any function, does it?

Hello Jagan,
To test it with GPIO, I also added this patch to my test bench :
https://patchwork.ozlabs.org/project/uboot/patch/[email protected]/
And then, I was able to test with GPIO : powering up a LED , powering it
down, also tested USB host by having the VBUS powered up by GPIO /
powered down.
Other pinctrl functions tested were to boot from SD-Card, in which
U-boot sets the right pinfunc for the SD pins.

gpio: pin A15 (gpio 15) value is 1
