There are a few issues in mailbox that needs to be fixed. - Send doorbell after an indirect cmd - Do not ring doorbell when polling mailbox response as it should've been sent by send_cmd - remove unneeded cmd_free_offset check - Fix mailbox initialization - Fix get_config_status returning a wrong status when the status is busy - Add command length in mailbox command header Signed-off-by: Tien Hock, Loh <tien.hock.loh@intel.com> Change-Id: If613e2ca889a540a616c62d69ad0086a7cd46536
