[U-Boot] [u-boot][PATCH] omap3_beagle: Fix device tree boot
Don't redefine fdtaddr and other values that are already defined in ti_armv7_common.h. The value of fdtaddr in ti_armv7_common.h is more appropriate as it allows a larger kernel image to be loaded.
With this change, I'm able to boot linux-4.0-rc1 with device tree blob.

With DEFAULT_LINUX_BOOT_ENV the bootm_size variable makes sure that we relocate the DT within the area that the kernel will see and we don't need fdt_high being set either.

I tried without fdt_high and the board wasn't booting. So we're still missing something for the omap3_beagle w.r.t that. Any clues?
