These + directories, and their purpose is listed below: + + arch-* machine/platform specific header files + hardware driver-internal ARM specific data structures/definitions + mach descriptions of generic ARM to specific machine interfaces + proc-* processor dependent header files (currently only two + categories) + + +Machine/Platform support +------------------------ + + The ARM tree contains support for a lot of different machine types. To + continue supporting these differences, it has become necessary to split + machine-specific parts by directory. For this, the machine category is + used to select which directories and files get included (we will use + $(MACHINE) to refer to the category) + + To this end, we now have arch/arm/mach-$(MACHINE) directories which are + designed to house the non-driver files for a particular machine (eg, PCI, + memory management, architecture definitions etc). For all future + machines, there should be a corresponding include/asm-arm/arch-$(MACHINE) + directory. + + Modules ------- |
