BYT - Byte width. B=1 means the device reads and
writes 9-bit memory bytes. B=0 means 8 bits.
DEVTYP2..0 - Device type. DEVTYP = 000 means
that this device is an RDRAM.
SPT - Split-core. SPT=1 means the core is split, SPT=0 means it is not.
CORG4..0 - Core organization. This field specifies the number of bank
(5 bits), row (9 bits), and column (6 bits) address bits.
SVER5..0 - Stepping version. Specifies the mask version number of this
device.

Device Identification register.
DEVID4..DEVID0 is compared to DR4..DR0,
DC4..DC0, and DX4..DX0 fields for all memory read
or write transactions. This determines which RDRAM
is selected for the memory read or write transaction.
