Hello arm-soc maintainers,

Please pull these fixes relating to OP-TEE, ftpm (firmware TPM), and tee_bnxt_fw (Broadcom BNXT firmware manager) drivers in kexec and kdump (emergency kexec) based workflows.

The two patches "firmware: tee_bnxt: Release TEE shm, session, and context during kexec" and "tpm_ftpm_tee: Free and unregister TEE shared memory during kexec" are acked by their respective maintainers.

For more details please see the description of the last patch set https://lore.kernel.org/lkml/20210614223317.999867-1-tyhicks@linux.microsoft...

Thanks, Jens
