I'm using this ARM9 SAM9G25 embedded system, that when switched on, is only online for a few seconds and because I want to speed up the whole process, I'd like to check the CPU frequency, and set it to max. speed.
The Linux 2.6.39 kernel is generated here with Buildroot 2013.10. When googeling around it in the end always leads to the "CPU frequency scaling" option, but that's not what I'm looking for. I believe there has to be some kind of a statically value for the CPU, so that e.g.: the kernel tells a 1 GHz CPU to operate at max. 100 MHz.
Can anyone point me in the right direction? Thanks for the support.
