Box" Date: Wed, 12 Apr 2023 18:32:30 -0700 Subject: platform/x86/intel/sdsi: Change mailbox timeout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On some platforms, it may take up to 400ms for the ready bit to be set in a successful mailbox transaction. Set the timeout to 500ms to cover the worst case. Signed-off-by: David E.
