tee: optee: Fix compilation issue with nommu
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.
