board. Its equipped with onboard DDR3, UART, ethernet, I2C, SPI NOR,
LCD and SATA (SSD) interfaces / devices.

Two defconfigs are added:

The production U-Boot version with a stripped down drivers and feature
list. This removes networking, USB and PCI support.

theadorable_debug_defconfig:
The debugging / testing U-Boot version with full support for all drivers.
