U-boot patches portal devices for adding new properties in portal nodes.
T4 devices such as T4240 have large number of portals. This requires extra
space in device tree blob. The large number of portals need more padding
space to be added.

This might be overridable so it could be overrided in the machine and
do not change the default for everyone.

What do you think?

Agreed. I suggest just making this change:

-KERNEL_DEVICETREE_FLAGS = "-R 8 -p 0x3000"
+KERNEL_DEVICETREE_FLAGS ?= "-R 8 -p 0x3000"

Then the machines/distros themselves can override this var.
