Hi,
These two patches complements the previously posted patchset "tee: optee: add dynamic shared memory support" https://lwn.net/Articles/740242/
Tests are added to see that the registered shared memory cache attributes are compatible with OP-TEE in secure world. Under normal circumstances they will be compatible, but if memory has been previously mapped from a device with special page attributes it could lead to trouble.
Thanks, Jens
