DEVICEID_VENDOR_ID:
Device ID and Vendor ID bit [15:7] are strapped in from top
level. These bits can be re-written from SETIDVALUE message 1st DW data byte 2, byte
3. for VLV/VLV2, final setting of this field is from SETIDVALUE message, while for TNG it
uses the strapped setting. For all SOC's, the RDL defalut is set to the strapped setting in
that SOC. Please refer to the SoC documentation to determine the proper Device ID for
the chip.

DEVICEID_bit_22_19 (DEVICEID_BIT_22_19):
Device ID [6:3] Hardwired in the
design. SETIDVALUE message will not re-write this field. RDL default is set to the
strapped value

RO
DEVICEID_bit_18_16 (DEVICEID_BIT_18_16):
Device ID [2:0]. Strapped in from
top level and tied to fuses to determine product SKU. SETIDVALUE message will not re-
write this field.
