In OP-TEE this goes down to:

#if defined(CFG_CORE_DYN_SHM)
          dyn_shm_en = core_mmu_nsec_ddr_is_defined();
          if (dyn_shm_en)
                  args->a1 |= OPTEE_SMC_SEC_CAP_DYNAMIC_SHM;
#endif

So either you have compiled OP-TEE without CFG_CORE_DYN_SHM enabled
(unlikely, it's the default), or core_mmu_nsec_ddr_is_defined() fails
which means OP-TEE doesn't know where your memory is. OP-TEE gets this
information from the device tree. Do you pass a device tree to OP-TEE?
barebox only does it when CONFIG_ARCH_ROCKCHIP_ATF_PASS_FDT is enabled
which currently is not the default as there are some Rockchip TF-A
binaries shipped by Rockchip which do not handle a fdt being passed.

Looking at your TF-A version you might have one of these, so you likely
have to update your TF-A to an upstream one.

Side note: Look at bl31_entry(). if it gets a fdt_addr that will be
passed to both TF-A and OP-TEE. You *could* try passing NULL as fdt to
atf_entry() to pass the fdt only to OP-TEE and not to TF-A, but I
wouldn't encourage that.
