What is the advantage of using TEX remapping ?

Applies to: ARM1136, ARM1176


TEX remapping frees up 2 bits in the TEX field that could be used by the OS for its own purposes. When TEX remapping is enabled, TEX bits [2:1] can be used by the OS and the memory attributes are defined by the TEX[0], C & B bits (and the CP15 S&R bits) and the values in the Primary Region Remap Register (PRRR) and the Normal Memory Remap Register (NMRR) (for cachable attributes). TEX remapping is disabled by default.
