From 93c4c0e4dd1e75449fd48fc629823629d0c9bb58 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Fri, 21 Oct 2022 19:58:31 -0500 Subject: arm: dts: imx8mn-u-boot: Create common imx8mn-u-boot.dtsi Multiple boards create duplicate entries in their respective -u-boot.dtsi files which all basically do the same thing. To consolidate these and make it easier to make improvements going forward, consolidate them all into one place. This file creates a flash.bin image using binman, and supports LPDDR4, DDR4 and DDR3. Since individual boards use different peripherals and different UART ports, those entries were kept in their respective board files, but the spba1 node was addded which contains all UART1-3 to help facilitate SPL_DM_SERIAL. Individual users will still need to include their respective UART and pinctrl nodes for those UARTS. This consolidated file also supports generating a flash.bin file which can boot from flexSPI if CONFIG_FSPI_CONF_HEADER is enabled.
