From 59b0d7d839f135bc44d3459784337a657149f8b3 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 10 May 2020 14:16:56 -0600 Subject: [PATCH] bdinfo: arm: Move ARM-specific info into its own file We don't really want to have ARM-specific code in a generic file. Create a new arch-specific function to hold it, and move it into that. Make the function weak so that any arch can implement it.
