From 8bba8954b1b6a155bf944b545ec9461fb2505e93 Mon Sep 17 00:00:00 2001 From: Lukasz Majewski Date: Mon, 27 Dec 2021 11:38:21 +0100 Subject: [PATCH] arm: xea: Modify board code to generate single binary u-boot This change provides the possibility to build XEA (imx287 based) board U-Boot as a single binary (without support for CONFIG_SPL_FRAMEWORK). The generated u-boot.sb can be used in the factory environment to for example perform initial setup or HW testing. It can be used with 'uuu' utility (SDPS: boot -f /srv/tftp/xea/u-boot.sb) In the configs/imx28_xea_defconfig one needs to disable following configs: # CONFIG_SPL_BLK is not set # CONFIG_SPL_FRAMEWORK is not set The board_init_ll() is used in arch/arm/cpu/arm926ejs/mxs/start.S, which is utilized when CONFIG_SPL_FRAMEWORK is disabled. However, when it is enabled - the arch/arm/cpu/arm926ejs/start.S is used, which requires the lowlevel_init() function.
