From 0afb22f4f199939ee30965495acf796f98519579 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 2 Mar 2023 04:08:30 +0100 Subject: [PATCH] test: cmd: fdt: Test fdt move Add 'fdt move' test which works as follows: - Create simple FDT, map it to sysmem - 'move' the FDT into new zeroed out sysmem location - Verify newly active FDT is in the new location - Compare both locations 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.
