There is no straightforward support for the TCMs - the details are
generally too cpu-specific to be useful in any generic way.

What you could try is:
- ensure the ITCM and DTCM are configured correctly (base/size etc.)
   For example in startup or program the CP15 registers yourself (the
   code that does this must be privileged via ThreadCtl _NTO_TCTL_IO)

- use mmap to directly map the ITCM physical address range.
   eg. mmap(0, size, PROT_READ|PROT_WRITE|PROT_EXEC|PROT_NOCACHE, MAP_SHARED|MAP_PHYS, NOFD, paddr)

- copy your code to the ITCM mapping
