+Intel Quark X10xx is the first product in the Quark family of SoCs. It is an IA-32
+(Pentium x86 ISA) compatible SoC. The core CPU in the X10xx is codenamed Lakemont.
+Lakemont version 1 (LMT1) is used in X10xx. The CPU TAP (Lakemont TAP) is used for
+software debug and the CLTAP is used for SoC level operations.
