From 556373e354eda76e74d30cc9221ea6fa4c88a048 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Fri, 22 Mar 2024 16:16:18 +0100 Subject: soc/amd/*/memmap: factor out common read_lower_soc_memmap_resources Since the code for reporting the memory map below cbmem_top is basically identical for all non-CAR AMD SoCs, factor this out into a common read_lower_soc_memmap_resources implementation.
