NAME
     spdmem -- Generic Memory Module Serial Presence Detect

SYNOPSIS
     spdmem* at iic? addr 0x50
     spdmem* at iic? addr 0x51
     spdmem* at iic? addr 0x52
     spdmem* at iic? addr 0x53

DESCRIPTION
     The spdmem driver provides support for generic memory module Serial Presence Detect.  During kernel boot it displays module type, and where
     possible, the size and rated speed of the memory module.  Additional information such as bank configuration and width is printed if the ker-
     nel is booted in verbose mode.

     The Serial Presence Detect data for each memory module is also made accessible to user mode via sysctl(8).  An entry for each spdmem device
     is created under the hw top-level MIB.
