Hi Hanjun,

Okay, so after talking with Al and Graeme on IRC, I think I understand
what is going on. The fact that ACPICA doesn't allow for both normal and
hardware reduced support in the same build is a very big problem.
However, it isn't a problem for ARM since we'll never support
non-hardware reduced mode. The x86 folks need to work that out when/if
they ever add support for hardware reduced mode.

I believe SMBIOS/DMI tables are only part of full ACPI, so there is a
need on ARM for more than hardware reduced mode.

You seem to be crossing the streams here, SMBIOS/DMI are not part of ACPI.

The only mention I can even find of them in the spec is you can cross reference
memory to its SMBIOS handle. Which is optional. It even says OSPM will not
use this value.
