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.
