 * Debugger for Intel Quark SoC X1000
 * 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.
 * Useful docs are here: https://communities.intel.com/community/makers/documentation
 * Intel Quark SoC X1000 OpenOCD/GDB/Eclipse App Note (web search for doc num 330015)
 * Intel Quark SoC X1000 Debug Operations User Guide (web search for doc num 329866)
 * Intel Quark SoC X1000 Datasheet (web search for doc num 329676)
 *
 * This file implements any Quark SoC specific features such as resetbreak (TODO)
