I am not marketing guy to say how often there are designs with only
different DDR size like Mike's example but in fpga world you are not
buying this chip to have only static part but you want to use fpga part
and for that you need to use design tools. Because every design is
unique you can generate device tree description directly from design
tools which covers your target and this is what I believe people use.
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.
