Subject: [PATCH] arch: arm: mach-socfpga: To notify SDM when SPL pass control to U-Boot
Date: Wed, 31 Aug 2022 14:29:39 +0800 [thread overview]
Message-ID: <20220831062939.10458-1-jit.loon.lim@intel.com> (raw)
From: Chin Liang See <chin.liang.see@intel.com>
Prior SPL pass control to U-Boot, SPL will send a mailbox command
"HPS_STAGE_NOTIFY" to notify Secure Device Manager (SDM) on HPS SW
transition.
The purpose is for debug as user can query SDM on HPS error details
when HPS enters a warm reset due to error such as watchdog.
