kernel hardware configuration file.............?

Hy all,
please tell me what kernel file holds the functions for the hardware configuration. I'm interested in finding the hardware timer of the linux and the DMA configuration file. I assume there is a single file that holds configuration data for the platform.This probably is executed before the kernel is started. As is see it this must be some hardware abstraction layer file because the actual kernel code is not platform dependent. Am i right? Please let me know where can it be found.

Thank you.

Nope.
(Most of) The kernel code that can be platform independent, is - that which isn't, (obviously) isn't. This is the reason for separate platform (sub-)trees in the source tree. Most of that level of code is in the native assembler for the specific platform.
