From 77291e6e90e9c84b9c963acb15d0cac381cf8b44 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 2 Mar 2023 04:08:43 +0100 Subject: [PATCH] test: cmd: fdt: Test fdt chosen Add 'fdt chosen' test which works as follows: - Create basic DT, map it to sysmem - Print /chosen node, verify it is nonexistent - Create chosen node - Print /chosen node, verify it contains only version - Create /chosen node with initrd entries - Print /chosen node, verify it contains version and initrd entries The test case can be triggered using: " ./u-boot -Dc 'ut fdt' " To dump the full output from commands used during test, add '-v' flag.
