From 6e18eec9080b0a079fc33a2ac8a7e2dd753944ee Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 29 Nov 2024 01:13:53 +0100 Subject: [PATCH] ARM: dts: imx: Make DRAM coding GPIOs available before relocation on Data Modul i.MX8M Mini/Plus eDM SBC The DRAM configuration GPIO straps must be accessible in SPL and before relocation because the GPIOs are sampled both in U-Boot SPL as well as early on in U-Boot proper. The already present bootph-pre-ram DT property made the GPIO controllers available in SPL, but not early on in U-Boot proper, which made gpio_request_list_by_name_nodev() in board dmo_get_memcfg() fail. Add missing bootph-some-ram DT property to all GPIO controllers which are referenced in dmo,ram-coding-gpios DT property to make those GPIO controllers available early in U-Boot proper as well.
