The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=1d5f967fa7776fd8119bab7fbe66bffde03e4735 commit 1d5f967fa7776fd8119bab7fbe66bffde03e4735 Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2023-02-03 15:38:29 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2023-02-03 15:41:39 +0000 kboot: Add powerpc stub for enumerate_memory_arch() Add stub for new MI interface for enumerating memory. Right now powerpc looks in the FDT table at a later point in boot since we don't need to pass a specific memory table to the kernel. Leave it like that for now, but note plans for the future.
