Subject: [PATCH 2/8] x86: start64: Add a hook at 64-bit entry
Date: Tue, 21 Apr 2020 17:45:01 -0700 [thread overview]
Message-ID: <20200422004507.2025-3-aiden.park@intel.com> (raw)
In-Reply-To: <20200422004507.2025-1-aiden.park@intel.com>
From: Aiden Park <aiden.park@intel.com>
This will allow a board or cpu to do its specific initialization
at 64-bit entry if U-Boot is a pure 64-bit binary.
Signed-off-by: Aiden Park <aiden.park@intel.com>
