Subject: [PATCH v2 2/2] board: amlogic: add meson_generate_serial_ethaddr fallback to p200
Date: Sun, 24 Mar 2024 15:19:05 +0000	[thread overview]
Message-ID: <20240324151905.3817732-3-christianshewitt@gmail.com> (raw)
In-Reply-To: <20240324151905.3817732-1-christianshewitt@gmail.com>

Add a fall-back method to generate ethaddr from CPU serial on p200 boards
if the MAC cannot be read from efuse. This prevents random MAC addresses
on the WeTek Hub/Play2 boards.
