From 2bd154360172d2ed2da78f7c484abd7acfcaec17 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Wed, 22 Mar 2023 16:59:31 -0300 Subject: [PATCH] imx6sx-udoo-neo-basic: Introduce the u-boot.dtsi After the conversion to DM_SERIAL in commit 4de0f15ee44d ("udoo_neo: Select DM_SERIAL and drop iomux board level init") the SPL log is gone and the U-Boot proper log becomes incomplete: Core: 80 devices, 18 uclasses, devicetree: separate MMC: FSL_SDHC: 1, FSL_SDHC: 2 Loading Environment from MMC... OK In: serial@2020000 Out: serial@2020000 Err: serial@2020000 Net: eth0: ethernet@2188000 Hit any key to stop autoboot: 0 Introduce the u-boot.dtsi file that passes the u-boot,dm-pre-reloc properties to the relevant nodes so that UART can be used early in SPL. With this change, the complete SPL and U-Boot messages are seen again.
