commit 264bf39788c9c1f5008e7c91b37632fa93fe6b15
Author: Ahmed BOUDJELIDA <aboudjel...@nanoxplore.com>

jtag/drivers: Add new driver for ANGIE USB-JTAG Adapter
This is a driver code for NanoXplore's ANGIE USB-JTAG Adapter.
The driver and firmware are based on the openULINK project.
Since the ANGIE Adapter has a Spartan-6 FPGA in addition to the
FX2 microcontroller, the driver adds a function "angie_load_bitstream"
that programs this FPGA.

+ * Definition of the commands supported by the ANGIE firmware.
+ *
+ * Basically, two types of commands can be distinguished:
+ * - Commands with fixed payload size
+ * - Commands with variable payload size
+ *
+ * SCAN commands (in all variations) carry payloads of variable size, all
+ * other commands carry payloads of fixed size.
+ *
+ * In the case of SCAN commands, the payload size (n) is calculated by
+ * dividing the scan_size_bits variable by 8, rounding up the result.
+ *
+ * Offset zero always contains the command ID.
