New Revision: 285726
URL: https://svnweb.freebsd.org/changeset/base/285726
Log:
MFC: r277949:
New function smbios_match to detect BIOS versions during boot
MFC: r277957:
Fix order of functions in smbios.c (corrects r277949)
MFC: r281138:
SMBIOS support for EFI
r281138 makes changes to the new unified EFI loader (r280950), which has not been merged to stable/10 (and likely won't be).
These changes were manually applied to the amd64 EFI loader (sys/boot/amd64/efi).
The changes to sys/boot/amd64/efi are a direct commit.
