18  * Debugger for Intel Quark SoC X1000
19  * Intel Quark X10xx is the first product in the Quark family of SoCs.
20  * It is an IA-32 (Pentium x86 ISA) compatible SoC. The core CPU in the
21  * X10xx is codenamed Lakemont. Lakemont version 1 (LMT1) is used in X10xx.
22  * The CPU TAP (Lakemont TAP) is used for software debug and the CLTAP is
23  * used for SoC level operations.
24  * Useful docs are here: https://communities.intel.com/community/makers/documentation
25  * Intel Quark SoC X1000 OpenOCD/GDB/Eclipse App Note (web search for doc num 330015)
