<content type='text'>
The optee driver uses specific page table types to verify if a memory
region is normal. These types are not defined in nommu systems. Trying
to compile the driver in these systems results in a build error:

  linux/drivers/tee/optee/call.c: In function ‘is_normal_memory’:
  linux/drivers/tee/optee/call.c:533:26: error: ‘L_PTE_MT_MASK’ undeclared
     (first use in this function); did you mean ‘PREEMPT_MASK’?
     return (pgprot_val(p) &amp; L_PTE_MT_MASK) == L_PTE_MT_WRITEALLOC;
                             ^~~~~~~~~~~~~
                             PREEMPT_MASK
  linux/drivers/tee/optee/call.c:533:26: note: each undeclared identifier is
     reported only once for each function it appears in
  linux/drivers/tee/optee/call.c:533:44: error: ‘L_PTE_MT_WRITEALLOC’ undeclared
     (first use in this function)
     return (pgprot_val(p) &amp; L_PTE_MT_MASK) == L_PTE_MT_WRITEALLOC;
                                            ^~~~~~~~~~~~~~~~~~~

Make the optee driver depend on MMU to fix the compilation issue.

Adds a OP-TEE driver which also can be compiled as a loadable module.

* Targets ARM and ARM64
* Supports using reserved memory from OP-TEE as shared memory
* Probes OP-TEE version using SMCs
* Accepts requests on privileged and unprivileged device
* Uses OPTEE message protocol version 2 to communicate with secure world
