Currently, the device tree relocation is disabled, likely to keep some DDR3 RAM at the end for Cortex-M4 firmwares. This can be archived using bootm_size, which limits the image processing range of the boot commands.
Move the device tree standard load address to a higher address which aligns better with what we are doing on other boards.
Signed-off-by: Stefan Agner stefan@agner.ch --- So this is the second version of the patch "arm: vf610: move device tree after kernel image" which makes use of bootm_size. I also added an appropriate comment, added variables for RAM disk, and added kernel_addr_r/fdt_addr_r.
