  "message": "gdbserver/csky add csky gdbserver support\n\nAdd new files:\n  gdb/arch/csky.c\n  gdb/arch/csky.h\n  gdb/features/cskyv2-linux.c\n  gdbserver/linux-csky-low.cc\n\n1. In gdb/arch/csky.c file, add function \"csky_create_target_description()\"\nfor csky_target::low_arch_setup(). later, it can be used for csky native gdb.\n\n2. In gdb/features/cskyv2-linux.c file, create target_tdesc for csky, include\ngprs, pc, hi, lo, float, vector and float control registers.\n\n3. In gdbserver/linux-csky-low.cc file, using PTRACE_GET/SET_RGESET to\nget/set registers. The main data structures in asm/ptrace.h are:\nstruct pt_regs {\n    unsigned long   tls;\n    unsigned long   lr;\n    unsigned long   pc;\n    unsigned long   sr;\n    unsigned long   usp;\n\n    /*\n     * a0, a1, a2, a3:\n     * r0, r1, r2, r3\n     */\n    unsigned long   orig_a0;\n    unsigned long   a0;\n    unsigned long   a1;\n    unsigned long   a2;\n    unsigned long   a3;\n\n    /*\n     * r4 ~ r13\n     */\n    unsigned long   regs[10];\n\n    /* r16 ~ r30 */\n    unsigned long   exregs[15];\n\n    unsigned long   rhi;\n    unsigned long   rlo;\n    unsigned long   dcsr;\n};\n\nstruct user_fp {\n    unsigned long   vr[96];\n    unsigned long   fcr;\n    unsigned long   fesr;\n    unsigned long   fid;\n    unsigned long   reserved;\n};\n",
