From f19312e5f400b1eb23252fa6d9e49a1e5512b448 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 31 Mar 2020 19:51:29 +0200 Subject: ARM: dts: stm32: Use DT alias for the configuration EEPROM Use DT /aliases node to establish a stable phandle to the configuration EEPROM. This permits the configuration EEPROM to be moved e.g. to a different address or a different bus. Adjust the board code to handle new phandle lookup.
