Subject: [PATCH 2/2] ARM: dts: microchip: sama5d29_curiosity: Add nvmem-layout in QSPI to describe EUI48 MAC address region
Date: Wed, 5 Mar 2025 15:31:34 +0530 [thread overview]
Message-ID: <20250305100134.1171124-2-manikandan.m@microchip.com> (raw)
In-Reply-To: <20250305100134.1171124-1-manikandan.m@microchip.com>
Add nvmem-layout in QSPI to describe EUI48 MAC address region.
This is useful for cases where U-Boot is skipped and the Ethernet
MAC address is needed to be configured in Linux.
