PHOLD limitation on Legacy Feature

PHOLD protocol is a mechanism for ISA to lock the system so that it can do a DMA.

Hence, the Intel Atom Processor D2000 series and N2000 series does NOT support

PHOLD protocol which impacts the devices behind LPC (ISA) Super I/O only (No LPC

mastering is allowed). These will need to be connected via USB adaptor if required.

This will not impact other legacy devices such as serial port, keyboard/mouse as well as

USB based peripheral. If one of these devices are connected to LPC and a PHOLD is

requested, Intel Atom Processor D2000 series and N2000 series will drop the request,

set an error bit, and the system will immediately hang.
