From 8a715530bb1f9522030757379415b174f3109951 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 19 Dec 2020 10:40:17 -0700 Subject: dm: core: Allow the uclass list to move At present the uclass list head is in global_data. This is convenient but with the new of-platdata we need the list head to be declared by the generated code. Change this over to be a pointer. Provide a 'static' version in global_data to retain the current behaviour.
