512 MiB: booting Linux with default environment not possible

The addresses used in default environment and in BSP FIT image generation expect variants with 1 GiB or more RAM. Can be fixed manually.

NFS boot: The interface to be used for NFS boot (netdev) has inverted order, compared to u-boot and Linux. Device renaming in Linux happens after mounting rootfs.

U-Boot:

• Not all USB sticks are detected properly.
• Using usb reset in U-Boot will give a warning from Type-C port controller.
  The USB controller is configured as device only via device tree to support serial download use case.
• boot from USB using uuu config displays misleading pinctrl / iomux warning.
  The UDC gadget driver warns not only for failed pinmux but also when no pinmux group is assigned in device tree.
