Subject: [PATCH v4 3/6] hw/arm/aspeed Update HW Strap Default Values for AST2700
Date: Mon, 3 Mar 2025 15:35:43 +0800	[thread overview]
Message-ID: <20250303073547.1145080-4-jamin_lin@aspeedtech.com> (raw)
In-Reply-To: <20250303073547.1145080-1-jamin_lin@aspeedtech.com>

Separate HW Strap Registers for SCU and SCUIO.
AST2700_EVB_HW_STRAP1 is used for the SCU (CPU Die) hw-strap1.
AST2700_EVB_HW_STRAP2 is used for the SCUIO (IO Die) hw-strap1.

Additionally, both default values are updated based on the dump from the EVB.
