+ * Each clock can have zero, one, or two dividers which change the
+ * output rate of the clock. Each divider can be either fixed or
+ * variable. If there are two dividers, they are the "pre-divider"
+ * and the "regular" or "downstream" divider. If there is only one,
+ * there is no pre-divider.
+ *
+ * A fixed divider is any non-zero (positive) value, and it
+ * indicates how the input rate is affected by the divider.
+ *
+ * The value of a variable divider is maintained in a sub-field of a
+ * 32-bit divider register. The position of the field in the
+ * register is defined by its offset and width. The value recorded
+ * in this field is always 1 less than the value it represents.
+ *
+ * In addition, a variable divider can indicate that some subset
+ * of its bits represent a "fractional" part of the divider. Such
+ * bits comprise the low-order portion of the divider field, and can
+ * be viewed as representing the portion of the divider that lies to
+ * the right of the decimal point. Most variable dividers have zero
+ * fractional bits. Variable dividers with non-zero fraction width
+ * still record a value 1 less than the value they represent; the
+ * added 1 does *not* affect the low-order bit in this case, it
+ * affects the bits above the fractional part only. (Often in this
+ * code a divider field value is distinguished from the value it
+ * represents by referring to the latter as a "divisor".)
+ *
+ * In order to avoid dealing with fractions, divider arithmetic is
+ * performed using "scaled" values. A scaled value is one that's
+ * been left-shifted by the fractional width of a divider. Dividing
+ * a scaled value by a scaled divisor produces the desired quotient
+ * without loss of precision and without any other special handling
+ * for fractions.
+ *
+ * The recorded value of a variable divider can be modified. To
+ * modify either divider (or both), a clock must be enabled (i.e.,
+ * using its gate). In addition, a trigger register (described
+ * below) must be used to commit the change, and polled to verify

 		CONFIG_SYS_LS_MC_DRAM_BLOCK_MIN_SIZE will be assumed.
 
+mcinitcmd:	This environment variable is defined to initiate MC and DPL deployment
+		from the location where it is stored(NOR, NAND, SD, SATA, USB)during
+		u-boot booting.If this variable is not defined then MC_BOOT_ENV_VAR

+		The variable needs to be set from the console once and then on
+		rebooting the parameters set in the varible will automatically be
+		executed. The commmand is demostrated taking an example of mc boot
+		using NOR Flash i.e. MC, DPL, and DPC is stored in the NOR flash:
+

+		noted that these addresses in 'fsl_mc start mc 0x580300000 0x580800000;fsl_mc apply DPL 0x580700000'
