+*
+* Language: ANSI C
+* Environment: Any
+* Developer: Kendall Bennett
+*
+* Description: This file includes subroutines to implement the decoding
+* and emulation of all the x86 processor instructions.
+*
+* There are approximately 250 subroutines in here, which correspond
+* to the 256 byte-"opcodes" found on the 8086. The table which
+* dispatches this is found in the files optab.[ch].
+*
+* Each opcode proc has a comment preceeding it which gives it's table
+* address. Several opcodes are missing (undefined) in the table.
+*
+* Each proc includes information for decoding (DECODE_PRINTF and
+* DECODE_PRINTF2), debugging (TRACE_REGS, SINGLE_STEP), and misc
+* functions (START_OF_INSTR, END_OF_INSTR).
+*
+* Many of the procedures are *VERY* similar in coding. This has
+* allowed for a very large amount of code to be generated in a fairly
+* short amount of time (i.e. cut, paste, and modify). The result is
+* that much of the code below could have been folded into subroutines
+* for a large reduction in size of this file. The downside would be
+* that there would be a penalty in execution speed. The file could
+* also have been *MUCH* larger by inlining certain functions which
+* were called. This could have resulted even faster execution. The
+* prime directive I used to decide whether to inline the code or to
+* modularize it, was basically: 1) no unnecessary subroutine calls,
+* 2) no routines more than about 200 lines in size, and 3) modularize
+* any code that I might not get right the first time. The fetch_*
+* subroutines fall into the latter category. The The decode_* fall
+* into the second category. The coding of the "switch(mod){ .... }"
+* in many of the subroutines below falls into the first category.
+* Especially, the coding of {add,and,or,sub,...}_{byte,word}
+* subroutines are an especially glaring case of the third guideline.
+* Since so much of the code is cloned from other modules (compare
+* opcode #00 to opcode #01), making the basic operations subroutine
+* calls is especially important; otherwise mistakes in coding an
+* "add" would represent a nightmare in maintenance.
+*
+* Jason ported this file to u-boot. place all the function pointer in
+* the got2 sector. Removed some opcode.

+*
+* Description: This file contains the code to implement the primitive
+* machine operations used by the emulation code in ops.c
+*
+* Carry Chain Calculation
+*
+* This represents a somewhat expensive calculation which is
+* apparently required to emulate the setting of the OF343364 and AF flag.
+* The latter is not so important, but the former is. The overflow
+* flag is the XOR of the top two bits of the carry chain for an
+* addition (similar for subtraction). Since we do not want to
+* simulate the addition in a bitwise manner, we try to calculate the
+* carry chain given the two operands and the result.
+*
+* So, given the following table, which represents the addition of two
+* bits, we can derive a formula for the carry chain.
+*
+* a b cin r cout
+* 0 0 0 0 0
+* 0 0 1 1 0
+* 0 1 0 1 0
+* 0 1 1 0 1
+* 1 0 0 1 0
+* 1 0 1 0 1
+* 1 1 0 0 1
+* 1 1 1 1 1
+*
+* Construction of table for cout:
+*
+* ab
+* r \ 00 01 11 10
+* |------------------
+* 0 | 0 1 1 1
+* 1 | 0 0 1 0
+*
+* By inspection, one gets: cc = ab + r'(a + b)
+*
+* That represents alot of operations, but NO CHOICE....
+*
+* Borrow Chain Calculation.
+*
+* The following table represents the subtraction of two bits, from
+* which we can derive a formula for the borrow chain.
+*
+* a b bin r bout
+* 0 0 0 0 0
+* 0 0 1 1 1
+* 0 1 0 1 1
+* 0 1 1 0 1
+* 1 0 0 1 0
+* 1 0 1 0 0
+* 1 1 0 0 0
+* 1 1 1 1 1
+*
+* Construction of table for cout:
+*
+* ab
+* r \ 00 01 11 10
+* |------------------
+* 0 | 0 1 0 0
+* 1 | 1 1 1 0
+*
+* By inspection, one gets: bc = a'b + r(a' + b)

+ * Notes :
+ * 1. #define __SIMULATE_ERROR__ to inject a CRC error into every 2nd TX
+ * packet to force the USB re-transmit protocol.
+ *
+ * 2. #define __DEBUG_UDC__ to switch on debug tracing to serial console
+ * be careful that tracing doesn't create Hiesen-bugs with respect to
+ * response timeouts to control requests.
+ *
+ * 3. This driver should be able to support any higher level driver that
+ * that wants to do either of the two standard UDC implementations
+ * Control-Bulk-Interrupt or Bulk-IN/Bulk-Out standards. Hence
+ * gserial and cdc_acm should work with this code.
+ *
+ * 4. NAK events never actually get raised at all, the documentation
+ * is just wrong !
+ *
+ * 5. For some reason, cbd_datlen is *always* +2 the value it should be.
+ * this means that having an RX cbd of 16 bytes is not possible, since
+ * the same size is reported for 14 bytes received as 16 bytes received
+ * until we can find out why this happens, RX cbds must be limited to 8
+ * bytes. TODO: check errata for this behaviour.
+ *
+ * 6. Right now this code doesn't support properly powering up with the USB
+ * cable attached to the USB host my development board the Adder87x doesn't
+ * have a pull-up fitted to allow this, so it is necessary to power the
+ * board and *then* attached the USB cable to the host. However somebody
+ * with a different design in their board may be able to keep the cable
+ * constantly connected and simply enable/disable a pull-up re
+ * figure 31.1 in MPC885RM.pdf instead of having to power up the board and
+ * then attach the cable !
