BAR Offset (BAROFST): Indicates the offset into the
BAR where the Index/Data pair are located (in Dword
granularity). The Index and Data I/O registers are located
at offset 10h within the I/O space defined by LBAR. A
value of 004h indicates offset 10h.
000h = 0h offset
001h = 4h offset
002h = 8h offset
003h = Bh offset
004h = 10h offset
FFFh = 3FFFh offset (max 16KB)
BAR Location (BARLOC): Indicates the absolute PCI
Configuration Register address of the BAR containing the
Index/Data pair (in Dword granularity). The Index and
Data I/O registers reside within the space defined by LBAR
in the SATA controller. A value of 8h indicates offset 20h,
which is LBAR.
