The new ARM_CP15_CTRL_XP is necessary to share ARMv6 and ARMv7 page-table formats and definitions. It enables the extended page tables (introduced in ARMv6) to be configured for the hardware page translation mechanism. This way we can share ARMv6 and ARMv7 page tables entry formats. Other Fault Status Register Definitions can be useful for debugging or excpetion handlers.
This is the README file for libcpu. This directory contains reusable libraries which are CPU dependent but not target board dependent. For example, the PowerPC has an on CPU decrementer register which may be used by all PowerPC BSP's for the Clock and Timer Drivers. Other examples include the caching support for the m68k CPU models and MIPS CPU model exception vectoring routines. This level of support will make it easier for others developing embedded applications on a given CPU.
