Volodymyr Babchuk f58e236c9d tee: optee: enable dynamic SHM support ... Previous patches added various features that are needed for dynamic SHM. Dynamic SHM allows Normal World to share any buffers with OP-TEE. While original design suggested to use pre-allocated region (usually of 1M to 2M of size), this new approach allows to use all non-secure RAM for command buffers, RPC allocations and TA parameters. This patch checks capability OPTEE_SMC_SEC_CAP_DYNAMIC_SHM. If it was set by OP-TEE, then kernel part of OP-TEE will use kernel page allocator to allocate command buffers. Also it will set TEE_GEN_CAP_REG_MEM capability to tell userspace that it supports shared memory registration.
