Jessica Clarke	b85b57e0f4	arm64: Don't rely on host readelf for u-boot booti image generation ... readelf is not a bootstrap tool and so cannot be relied upon to exist. On macOS there is no system readelf, and even on Linux or FreeBSD where it does exist, BUILD_WITH_STRICT_TMPPATH builds won't be able to use it. Instead of making it a bootstrap tool, just use nm as that suffices and already is a bootstrap tool. Fixes: 28482babd0 ("arm64: Use new arm_kernel_boothdr script for generating booti images.")

Michal Meloun	8e3cc69a4e	booti: Enable loading the kernel image to any address aligned to 2 MB ... We've supported this for a long time, plus most u-boot setups quietly expect MFC after: 2 weeks (cherry picked from commit b07a6bd15a)	2022-01-20 11:10:21 +01:00
Michal Meloun	59f46e34cf	sys/tools: Add a tool for generating arm and arm64 kernel images. ... This tool can generate kernel images without changing the offsets in the final executable. It replaces the ELF header by properly sized zeroed block then emits a relative jump to _start(for 'v7jump' or 'v8jump' option) or the booti header (for 'v8booti' option) to the beginning of the converted file.
