Prefetchable Memory Block
With this bit set, there are no side effects to prefetching.
For reads, all bytes can be sent regardless of the state of
the byte enables. For writes, sequential writes can be
combined into a burst.
Location of Memory
With bit 2 = 1 and bit 1 = 0, the user can map this device
anywhere in the 64-bit space.
I/O or Memory Space Indicator (Read Only)
This bit is set to "0" to indicate Memory Space mapping.
