The GARDENA smart Gateway boards are equipped with an Atmel / Microchip
AT91SAM9G25 SoC and with 128 MiB of RAM and 256 MiB of NAND storage.
This patch adds support for this board including SPL support. Therefore
the AT91Boostrap is not needed on this platform any more.

Some factory data is stored in the SPI NOR and needs to get extracted
from there into U-Boot environment variables.

This patch also includes a board-specific command "fd_write" to
provide some dummy / default values for this factory-data in the SPI
NOR flash. This should only be necessary for testing purposes though.

This is needed to set the LEDs automatically to a default state, as
configured in the dts.

The Gardena Smart-Gateway boards have a MT7688 SoC with 128 MiB of RAM
and 8 MiB of flash (SPI NOR) and additional 128MiB SPI NAND storage.

This patch also includes 2 targets. One is the target that can be
programmed into the SPI NOR flash and a 2nd target "xxx-ram" is
added to support loading and booting via an already running U-Boot
version. This allows easy development and testing without the
need to flash the image each time.
