From aa89aebb17531a3e8b6729c812a68d5e37008730 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 2 Mar 2023 04:08:40 +0100 Subject: [PATCH] test: cmd: fdt: Test fdt bootcpu Add 'fdt bootcpu' test which works as follows: - Create basic FDT, map it to sysmem - Print the FDT bootcpu - Set the FDT bootcpu and read the value back using 'fdt header get' - Perform the previous step twice to validate bootcpu overwrite 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.
