commit 090eeeb1631f00a9a41ebf66d9b4aacb97eb51e7 Author: Juergen Gross <jgross@xxxxxxxx> AuthorDate: Wed Dec 6 17:17:44 2023 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Thu Dec 7 18:53:04 2023 +0000 Mini-OS: don't use objcopy --dump-section The objcopy option "--dump-section" isn't supported in binutils before version 2.25, which are still supported by the Xen build system. Avoid that by using the "-O binary" format together with "--only-section". This requires to set the "alloc" section flag.
