Subject: [PATCH v5 6/6] MIPS: DTS: CI20: make DM9000 Ethernet controller use NVMEM to find the default MAC address
Date: Sat, 22 Feb 2020 11:25:41 +0100 [thread overview]
Message-ID: <aa411ab2b57443b405372cc54c95bffc326aff98.1582367141.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1582367141.git.hns@goldelico.com>
There is a unique MAC address programmed into the eFuses
of the JZ4780 chip in the CI20 factory. By using this
for initializing the DM9000 Ethernet controller, every
CI20 board has an individual - but stable - MAC address
and DHCP can assign stable IP addresses.
