Linus Walleij	1dbd30e989	ARM: 6225/1: make TCM allocation static and common for all archs ... This changes the TCM handling so that a fixed area is reserved at 0xfffe0000-0xfffeffff for TCM. This areas is used by XScale but XScale does not have TCM so the mechanisms are mutually exclusive. This change is needed to make TCM detection more dynamic while still being able to compile code into it, and is a must for the unified ARM goals: the current TCM allocation at different places in memory for each machine would be a nightmare if you want to compile a single image for more than one machine with TCM so it has to be nailed down in one place.

Linus Walleij	610ea6c671	ARM: 5738/1: Correct TCM documentation ... It turns out that the TCM memory can be remap:ed by the MMU just like any other memory.

Linus Walleij	bc581770cf	ARM: 5580/2: ARM TCM (Tightly-Coupled Memory) support v3 ... This adds the TCM interface to Linux, when active, it will detect and report TCM memories and sizes early in boot if present, introduce generic TCM memory handling, provide a generic TCM memory pool and select TCM memory for the U300 platform.
