From fadfc184efebb79b77d9c5fa24db0f1b89957277 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Tue, 13 Nov 2018 15:01:16 +0100 Subject: ARM: davinci: dm850-evm: use cell nvmem lookup for mac address We now support nvmem lookups and cell definitions for machine code. Add relevant data structures for the mac-address stored in at24 EEPROM.
