From 1171adfd89904eb4f299da22deaa0731ed5f2957 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 29 Nov 2024 01:13:54 +0100 Subject: [PATCH] ARM: dts: imx: Pick safe DRAM size on failure on Data Modul i.MX8M Mini/Plus eDM SBC In case gpio_request_list_by_name_nodev() in board dmo_get_memcfg() returns error code, pick a safe default DRAM configuration instead of bailing out with some sort of hang() or panic(). The BIT(2)|BIT(0) strap option is the lowest known option of 2 GiB , use that.
