Well, I can't speak for everyone...

Most people don't want to write (or even compile) a new bootloader for each 
and every project. For our Miami SOMs, there are already more full-custom 
carrier boards than evaluation boards. If we had to build a bootloader for 
each such design, there'd be dozens of them.

What we try to do is just use the generic bootloader to get the SOM up and 
running, and then provide all the project hardware details in the kernel's 
final devicetree. That includes changing pinmuxing and clocks and stuff, which 
is easy to do.
