[U-Boot] arm am335x: SATA Drive connectivity over USB interface

[Adarsh Babu Kalepalli]

Hi,

u-boot Version: 2019.10-rc4
u-boot config : am335x-evm-defconfig
h/w Board: Beaglebone Black

Using a SATA-USB converter, 180GB SATA disk is interfaced with Beaglebone
Black.
Unable to initialze and access the device with "usb start" and other usb
command options.

Serial Console output of 'usb start' command:

---------------------------
BBB=> usb start
starting USB...
Bus usb at 47401800: Port not available.
---------------------------

Beaglebone Linux environment identifies this SATA disk over USB interface.

Are additional config options required by u-boot??If yes, please let us
know.

Regards,
Adarsh
