Vincenzo Frascino 281f32e343 tee: optee: Fix compilation issue with nommu 
[ Upstream commit 9e0caab8e0 ]

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) & 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) & L_PTE_MT_MASK) == L_PTE_MT_WRITEALLOC;
                                            ^~~~~~~~~~~~~~~~~~~

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

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
