By default on this platform, u-boot loads data into high memory
in the range of 0x7Fxxxxxx, which generates a data abort when the
kernel tries to read it. Config the u-boot environment to load
the device tree and initrd image into lower memory to make them
accessible to the kernel.

The ARM Trusted Firmware or other security solutions are
eating memory from the top of the physical SDRAM1 space,
moving backward from 0xffffffff, currently occupying e.g.

This solution to reserving memory for secure world is not
optimal, so we need to think of how the secure world and
earlier boot stages should communicate to U-Boot what
memory they are eating up. For now let's just put 16MB
aside.
Also enable the memory test command and define start and
