libfdt: Update to 1.4.6, switch to using libfdt for overlay support libfdt highlights since 1.4.3: - fdt_property_placeholder added to create a property without specifying its value at creation time - stringlist helper functions added to libfdt - Improved overlay support - Various internal cleanup Also switch stand/fdt over to using libfdt for overlay support with this update. Our current overlay implementation works only for limited use cases with overlays generated only by some specific versions of our dtc(1). Swap it out for the libfdt implementation, which supports any properly generated overlay being applied to a properly generated base. This will be followed up fairly soon with an update to dtc(1) in tree to properly generate overlays. MFC note: the <stdlib.h> include this update introduces in libfdt_env.h is apparently not necessary in the context we use this in. It's not immediately clear to me the motivation for it being introduced, but it came in with overlay support. I've left it in for the sake of accuracy and because it's not harmful here on HEAD, but MFC'ing this to stable/11 will require wrapping the #include in an `#ifndef _STANDALONE` block or else it will cause build failures.

EFI secure boot VECTX related changes When VECTX is enabled as a kernel option and non-EFI loaders are built, many reads will fail due to the mis-match of whether LOADER_VERIEXEC_VECTX or not in readin.h. Source that includes bootstrap.h must ensure the kernel option agrees with the compile time CFLAGS in the various make related files.
