Andreas Fritiofson 0ecb0396d4 nds32: Use the correct method to access registers
The registers are represented as bit arrays intended to be accessed using
the buf_set_* and buf_get_* functions. Storing the register values in
integers enables accessing them directly, which gives different results
depending on host byte order.

Convert the register store to use a byte array instead and fix all the
byte order bugs uncovered by that.

Also merge the 32 and 64 bit register fields. Only one of them is used at
a time and after the change to byte arrays their types are also the same.

Hsiangkai Wang 0a4c8990c2 gdb_server: support File-I/O Remote Protocol Extension
The File I/O remote protocol extension allows the target to use the
host's file system and console I/O to perform various system calls.

To use the function, targets need to prepare two callback functions:
* get_gdb_finish_info: to get file I/O parameters from target
* gdb_fileio_end: pass file I/O response to target

As target is halted, gdb_server will try to get file-I/O information
from target through target_get_gdb_fileio_info(). If the callback function
returns ERROR_OK, gdb_server will initiate a file-I/O request to gdb.
After gdb finishes system call, gdb will pass response of the system call
to target through target_gdb_fileio_end() and continue to run(continue or step).

To implement the function, I add a new data structure in struct target,
called struct gdb_fileio_info, to record file I/O name and parameters.

Details refer to GDB manual "File-I/O Remote Protocol Extension"

Hsiangkai Wang d979d78e97 gdb_server: support gdb target description
* Add a parameter in .get_gdb_reg_list() to return different
  register lists as generating target description.
* Modify STRUCT REG to let gdb generate target description
  according to register information.

The modified structure of register is
struct reg {
        const char *name;
        uint32_t number;  /* for regnum="num" */
        struct reg_feature *feature;  /* for register group feature name */
        bool caller_save;  /* for save-restore="yes|no" */
        void *value;
        bool dirty;
        bool valid;
        bool exist;
        uint32_t size;
        struct reg_data_type *reg_data_type;  /* for type="type" */
        const char *group;  /* for group="general|float|vector" */
        void *arch_info;
        const struct reg_arch_type *type;
};

Hsiangkai Wang ceb402dc9e aice: add Andes AICE support
Andes AICE uses USB to transfer packets between OpenOCD and AICE.
It uses high-level USB commands to control targets instead of using
JTAG signals. I define an interface as aice_port_api_s. It contains
all basic operations needed by target-dependent code.
