Hi Igor,
My personal opinion is that unless you intend to run the binary on
multiple IMX6 variants, there's no
need to do expensive checks in runtime, when you can do the same at
compile-time. For me it's the
same as choosing puts() vs printf() - you know at compile time whether
you need to print arguments
or not, so same with the USB controller base address - you know in
advance that you target a specific
CPU variant and not the other ones.
To a certain extent I agree that it would be awesome to have the same
code running on all IMX6
variants, but the run-time checks will increase somewhat the binary
footprint and U-Boot community has
already gone to great efforts to remove unnecessary bloat. My personal
assumption is that such generic
approach would be more tolerated in the Linux kernel.
Kind regards,
Nikolay

you can check the SoC type in runtime, right? And then substitute the
correct address in a variable or so... I would really prefer such kind
of things done in runtime.
