The branch stable/13 has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=ef72e52e8e0e26590e85ce8a96ac0bcfae6807ab commit ef72e52e8e0e26590e85ce8a96ac0bcfae6807ab Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2023-01-25 18:31:00 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2023-01-25 18:33:20 +0000 stand/mips: retire BERI boot loader The folks that created the BERI boot loader no longer need it. They've long since moved on to other research platforms. Since BERI loader contains yet another copy of code that I've consolodated; and since it's impossible to test this platform; and since there are no users, retire it completely to ease future MFCs.
