19   Register names for VLV PCI-E root port devices
20 
21   Conventions:
22 
23   - Prefixes:
24     Definitions beginning with "R_" are registers
25     Definitions beginning with "B_" are bits within registers
26     Definitions beginning with "V_" are meaningful values of bits within the registers
27     Definitions beginning with "S_" are register sizes
28     Definitions beginning with "N_" are the bit position
29   - In general, PCH registers are denoted by "_PCH_" in register names
30   - Registers / bits that are different between PCH generations are denoted by
31     "_PCH_<generation_name>_" in register/bit names. e.g., "_PCH_VLV_"
32   - Registers / bits that are different between SKUs are denoted by "_<SKU_name>"
33     at the end of the register/bit names
34   - Registers / bits of new devices introduced in a PCH generation will be just named
35     as "_PCH_" without <generation_name> inserted.
