@ -29,11 +29,13 @@ TCM location and size. Notice that this is not a MMU table: you
actually move the physical location of the TCM around. At the
place you put it, it will mask any underlying RAM from the
CPU so it is usually wise not to overlap any physical RAM with
the TCM. The TCM memory exists totally outside the MMU and will
override any MMU mappings.
the TCM.
Code executing inside the ITCM does not "see" any MMU mappings
and e.g. register accesses must be made to physical addresses.
The TCM memory can then be remapped to another address again using
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.
TCM is used for a few things:
