+/**********************************************************************
+ * How it works:
+ * -------------
+ * The framelist / Transfer descriptor / Queue Heads are similar like
+ * in the linux usb_uhci.c.
+ *
+ * During initialization, the following skeleton is allocated in init_skel:
+ *
+ *         framespecific           |           common chain
+ *
+ * framelist[]
+ * [  0 ]-----> TD ---------\
+ * [  1 ]-----> TD ----------> TD ------> QH -------> QH -------> QH ---> NULL
+ *   ...        TD ---------/
+ * [1023]-----> TD --------/
+ *
+ *              ^^             ^^         ^^          ^^          ^^
+ *              7 TDs for      1 TD for   Start of    Start of    End Chain
+ *              INT (2-128ms)  1ms-INT    CTRL Chain  BULK Chain
+ *
+ *
+ * Since this is a bootloader, the isochronous transfer descriptor have been removed.
+ *
+ * Interrupt Transfers.
+ * --------------------
+ * For Interupt transfers USB_MAX_TEMP_INT_TD Transfer descriptor are available. They
+ * will be inserted after the appropriate (depending the interval setting) skeleton TD.
+ * If an interrupt has been detected the dev->irqhandler is called. The status and number
+ * of transfered bytes is stored in dev->irq_status resp. dev->irq_act_len. If the
+ * dev->irqhandler returns 0, the interrupt TD is removed and disabled. If an 1 is returned,
+ * the interrupt TD will be reactivated.
+ *
+ * Control Transfers
+ * -----------------
+ * Control Transfers are issued by filling the tmp_td with the appropriate data and connect
+ * them to the qh_cntrl queue header. Before other control/bulk transfers can be issued,
+ * the programm has to wait for completion. This does not allows asynchronous data transfer.
+ *
+ * Bulk Transfers
+ * --------------
+ * Bulk Transfers are issued by filling the tmp_td with the appropriate data and connect
+ * them to the qh_bulk queue header. Before other control/bulk transfers can be issued,
+ * the programm has to wait for completion. This does not allows asynchronous data transfer.

+ * - internal clock = SYSCLK / 2
+ *
+ * EXTERNAL EFFECTS:
+ *
+ * After calling this function, the MPC860ESAR UTOPIA bus is

+   alpha=2 is the primitive element of GF(2**m)
+   HARI's COMMENT: (4/13/94) alpha_to[] can be used as follows:
+        Let @ represent the primitive element commonly called "alpha" that
+   is the root of the primitive polynomial p(x). Then in GF(2^m), for any
+   0 <= i <= 2^m-2,
+        @^i = a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
+   where the binary vector (a(0),a(1),a(2),...,a(m-1)) is the representation
+   of the integer "alpha_to[i]" with a(0) being the LSB and a(m-1) the MSB. Thus for
+   example the polynomial representation of @^5 would be given by the binary
+   representation of the integer "alpha_to[5]".
+                   Similarily, index_of[] can be used as follows:
+        As above, let @ represent the primitive element of GF(2^m) that is
+   the root of the primitive polynomial p(x). In order to find the power
+   of @ (alpha) that has the polynomial representation
+        a(0) + a(1) @ + a(2) @^2 + ... + a(m-1) @^(m-1)
+   we consider the integer "i" whose binary representation with a(0) being LSB
+   and a(m-1) MSB is (a(0),a(1),...,a(m-1)) and locate the entry
+   "index_of[i]". Now, @^index_of[i] is that element whose polynomial
+    representation is (a(0),a(1),a(2),...,a(m-1)).
+   NOTE:
+        The element alpha_to[2^m-1] = 0 always signifying that the
+   representation of "@^infinity" = 0 is (0,0,0,...,0).
+        Similarily, the element index_of[0] = A0 always signifying
+   that the power of alpha which has the polynomial representation
+   (0,0,...,0) is "infinity".

+
+  Polynomials over GF(2) are represented in binary, one bit per coefficient,
+  with the lowest powers in the most significant bit.  Then adding polynomials
+  is just exclusive-or, and multiplying a polynomial by x is a right shift by
+  one.  If we call the above polynomial p, and represent a byte as the
+  polynomial q, also with the lowest power in the most significant bit (so the
+  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
+  where a mod b means the remainder after dividing a by b.
+
+  This calculation is done using the shift-register method of multiplying and
+  taking the remainder.  The register is initialized to zero, and for each
+  incoming bit, x^32 is added mod p to the register if the bit is a one (where
+  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
+  x (which is shifting right by one and adding x^32 mod p if the bit shifted
+  out is a one).  We start with the highest power (least significant bit) of
+  q and repeat for all eight bits of q.
+
+  The table is simply the CRC of all possible eight bit values.  This is all
+  the information needed to generate CRC's on data a byte at a time for all
+  combinations of CRC register values and incoming bytes.
