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. See the Documentation/arm/tcm.txt for documentation. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
