There is further a TCM region register (search for "TCM Region

Registers" at the ARM site) that can report and modify the location

the MMU, but notice that the TCM if often used in situations where

the MMU is turned off. To avoid confusion the current Linux

implementation will map the TCM 1 to 1 from physical to virtual

memory in the location specified by the machine.

memory in the location specified by the kernel. Currently Linux

will map ITCM to 0xfffe0000 and on, and DTCM to 0xfffe8000 and

on, supporting a maximum of 32KiB of ITCM and 32KiB of DTCM.

Newer versions of the region registers also support dividing these

TCMs in two separate banks, so for example an 8KiB ITCM is divided

into two 4KiB banks with its own control registers. The idea is to

be able to lock and hide one of the banks for use by the secure

world (TrustZone).

TCM is used for a few things:

  memory. Such a heap is great for things like saving

  device state when shutting off device power domains.

A machine that has TCM memory shall select HAVE_TCM in

arch/arm/Kconfig for itself, and then the

rest of the functionality will depend on the physical

location and size of ITCM and DTCM to be defined in

mach/memory.h for the machine. Code that needs to use

TCM shall #include <asm/tcm.h> If the TCM is not located

at the place given in memory.h it will be moved using

the TCM Region registers.

A machine that has TCM memory shall select HAVE_TCM from

arch/arm/Kconfig for itself. Code that needs to use TCM shall

#include <asm/tcm.h>

Functions to go into itcm can be tagged like this:

int __tcmfunc foo(int bar);

Since these are marked to become long_calls and you may want

to have functions called locally inside the TCM without

wasting space, there is also the __tcmlocalfunc prefix that

will make the call relative.

Variables to go into dtcm can be tagged like this:

int __tcmdata foo;
