I consider it acceptable to have  "include/configs/<board>.h" to be constant 
for most users
of my S/W; but the networking environment will be different.
This is different for each user.
The memory configuration is also different.

This is a major undertaking and a long term project, which I have no chance 
of driving.
If someone decides that u-boot should be configured as part of the buildroot
configuration, then I can contribute.

Buildroot will allow me to create the contents of the board.h file in an 
incremental fashion
if I let the automatically generated info override the board.h files.  I 
like that.
I do not need to test any boards that I do not have access to.

I am not sure I agree that I keep everyone in the dark since I publish the 
source of my buildroot tree.
I would not have any problem providing this and my Atmel customized U-boot 
to you for inclusion in your ftp site.
