I ACK the idea, but there are a few changes I would make to your patch,
see below.

We don't usually have question marks in option names.

Just nitpicking, but IMO the newcomer might find it confusing: we are
always downloading U-Boot sources, so what does this option change?

I would replace "specified for U-Boot" with "specified for the uboot
package". This makes it more clear that you refer to the "uboot"
package in Buildroot.

This is just a clarification, there is nothing wrong in your wording.

You are overriding the previously-defined options. I find an
if/then/else construct much cleaner:

ifneq ($(BR2_PACKAGE_UBOOT_TOOLS_UBOOT_SOURCE),y)
...use upstream sources... (current code)
else
...use sources for the uboot package...
endif

This should be an ifneq, not ifeq.
