From b833de8d42663e157ce0039c5a7771f5d4aef11e Mon Sep 17 00:00:00 2001 From: Tien Fong Chee Date: Wed, 24 Jul 2024 17:35:09 +0800 Subject: [PATCH] arm: socfpga: Add handoff data support for SoCFPGA Agilex5 device Agilex5 supports both HPS handoff data and DDR handoff data. Existing HPS handoff functions are restructured to support both existing devices and Agilex5 device.
