Provide mechanism to check mailbox queue length before posting new
message to mailbox queue.
Changes in v2:
- Split patchset in two patches for two different subsystems.
- Change design and introduce new field per channel to track mbox
queue length.
- use this new field in xlnx remoteproc driver to prevent sending new
messages if no slots available in the mbox tx channel queue.
Tanmay Shah (2):
mailbox: check mailbox queue is full or not
remoteproc: xlnx: do not kick if mbox queue is full
