Generic I/O Decode Range 2 Base Address (GEN2_BASE) — R/W. This address is aligned on a
64-byte boundary, and must have address lines 31:16 as 0.
Note that this generic decode is for I/O addresses only, not memory addresses. The size of this
range is 16 bytes.
Reserved. Read as 0
Generic I/O Decode Range 2 Enable (GEN2_EN) — R/W.
0 = Disable
1 = Accesses to the GEN2 I/O range will be forwarded to the LPC I/F
