[U-Boot] [PATCH 1/4] Add support for BeagleBoard.org PocketBeagle

[David Summers]

> [U-Boot] [PATCH 1/4] Add support for BeagleBoard.org PocketBeagle
> ------------------------------------------------------------------------
> Texas Instruments AM3358 based low-cost board using Octavo Systems OSD3358 SIP
> with built-in TPS65217 PMIC and 512MB DDR3. Board features small 35mm x
> 55mm size, high-speed USB OTG, microSD and 72 0.1" expansion header
> pins with 2xSPI, 2xI2C, 2xUART, USB, 8xADC, up-to-44 GPIO, PRU pins and much more.

>
> This was tested using the am335x_evm_usbspl_defconfig.
>
> Note that MII pins are enabled despite not having Ethernet on this
> board. This avoids an issue where otherwise many timeout errors would be
> generated. Seehttps://e2e.ti.com/support/arm/sitara_arm/f/791/t/298976
> for some related discussion.

Also tested, applied to 2018.03-rc4 and tested on a Pocket Beagle. The 
patch works as intended.
