YOu copy things to binaries/PROJECT to have a single directory
which you can compress, but if you copy the stuff to
the tftp directory then you have a mess.
You have to manually rename this.

The kernel is already doing this in the "advanced" makefile.

The rootfs should be doing it. and in this case PROJECT Is definitely
the right one to use.

Yes and no,

You can use BR2_PROJECT, but if you:

make XXXX_config 
when building u-boot-<VERSION>, it also makes sense to name the binary

<XXXX>-u-boot-<VERSION>-<DATE>.bin

because regardless of which project you are building,
the binary should end up the same.

<DATE> is there to give you some kind of revision information
so you do not overwrite older working results.
It is not perfect, but I think it is good enough.

If you are building several projects where the U-Boot differs
I.E: if a header file is first copied to "include/configs" 
then it would make sense to call it:

<PROJECT>-u-boot-<VERSION>-<DATE>.bin

The difference is minor, so I guess we go with PROJECT for now.
