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/[email protected]/
Thanks,
Jens
