New Revision: 335231
URL: https://svnweb.freebsd.org/changeset/base/335231
Log:
There's no need to walk through the tables looking for the smbios
table if we're just going to ignore it on arm, so expand, slightly,
the reach of the ifdef. Move the buffer to the inner block so we
don't have a separate #ifdef far away from these lines.
The issue on arm is that smbios_detect does unaligned accesses, which
in the u-boot implementing EFI context causes a crash.
