From e3aabea3e6c701c8d47813a7cbc3b90767ba2ff1 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 2 Mar 2023 04:08:31 +0100 Subject: [PATCH] test: cmd: fdt: Test fdt resize Add 'fdt resize' test which works as follows: - Create simple FDT with extra size 0, map it to sysmem - 'resize' the FDT by 0x2000 bytes - Verify the new space has been added to the FDT 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.
