Hello arm-soc maintainers,
Please pull this small patch for the OP-TEE driver to remove the invalid
size check of outgoing memref parameters. This code path is only
activated for a certain configuration of OP-TEE in secure world
(CFG_CORE_DYN_SHM=n) so this problem isn't always visible.

The previous pull request for OP-TEE tracepoints introduced a build

Hello arm-soc maintainers,
Please pull these patches enabling multi-stage OP-TEE bus enumeration
and also adds a TPM driver for a OP-TEE based fTPM Trusted Application.
The TPM driver depends on and takes advantage of the multi-stage OP-TEE bus
