The set of patches that I am asking Linus to pull now can use the ACPI table
to find the table or in the fallback case the old method of scanning the
memory. However if the machine has UEFI it will only do ACPI table lookup.
Can you point me what 'standard ACPI mechanism' is? Like sticking the code in
the drivers/acpi ? And then having a generic driver to handle the
[i,a,s,m]BFT tables and maybe some subordinate ones for specific pieces where
the generic can't handle it?

What is the tools state ? For iBFT, iscsi-initiator-utils scans
the /sys/firmware directory to extract the relevant data and does its thing.
Are there tools for AoE, SCSI RDMA Protocol (SRP), and in-memory disk?
