+ * Public Functions
+ ****************************************************************************/
+
+/****************************************************************************
+ * Name: up_fillpage()
+ *
+ * Description:
+ * After a page is allocated and mapped by up_allocpage(), the actual
+ * filling of the page with data from the non-volatile, must be performed
+ * by a separate call to the architecture-specific function, up_fillpage().
+ * This function is non-blocking, it will start an asynchronous page fill.
+ * The common paging logic will provide a callback function, pg_callback,
+ * that will be called when the page fill is finished (or an error occurs).
+ * This callback is assumed to occur from an interrupt level when the
+ * device driver completes the fill operation.
+ *
+ * NOTE 1: Allocating and filling a page is a two step process. up_allocpage()
+ * allocates the page, and up_fillpage() fills it with data from some non-
+ * volatile storage device. This distinction is made because up_allocpage()
+ * can probably be implemented in board-independent logic whereas up_fillpage()
+ * probably must be implemented as board-specific logic.
+ *
+ * NOTE 2: The initial mapping of vpage will be read-able, write-able,
+ * but non-cacheable. No special actions will be required of
+ * up_fillpage() in order to write into this allocated page. If the
+ * virtual address maps to a text region, however, this function should
+ * remap the region so that is is read/execute only. It should be made
+ * cache-able in any case.
+
+ * Input Parameters:
+ * tcb - A reference to the task control block of the task that needs to
+ * have a page fill. Architecture-specific logic can retrieve page
+ * fault information from the architecture-specific context
+ * information in this TCB to perform the fill.
+ * pg_callbck - The function to be called when the page fill is complete.
+ *
+ * Returned Value:
+ * This function will return zero (OK) if the page fill was successfully
+ * started (the result of the page fill is passed to the callback function
+ * as the result argument). A negated errno value may be returned if an
+ * error occurs. All errors, however, are fatal.
+ *
+ * NOTE: -EBUSY has a special meaning. It is used internally to mean that
+ * the callback function has not executed. Therefore, -EBUSY should
+ * never be provided in the result argument of pg_callback.
+ *
+ * Assumptions:
+ * - This function is called from the normal tasking context (but
+ * interrupts siabled). The implementation must take whatever actions
+ * are necessary to assure that the operation is safe within this context.
+ * - Upon return, the caller will sleep waiting for the page fill callback
+ * to occur. The callback function will perform the wakeup.

+ * Micron Initialization Sequence from their data sheet for the Micron
+ * MT48LC32M16A2 32M x 16 SDRAM chip:
+ *
+ * "SDRAMs must be powered up and initialized in a predefined manner.
+ * Operational procedures other than those specified may result in
+ * undefined operation. Once power is applied to VDD and VDDQ
+ * (simultaneously) and the clock is stable (stable clock is defined as
+ * a signal cycling within timing constraints specified for the clock
+ * pin), the SDRAM requires a 100µs delay prior to issuing any command
+ * other than a COMMAND INHIBIT or NOP.
+ *
+ * "Starting at some point during this 100µs period and continuing at least
+ * through the end of this period, COMMAND INHIBIT or NOP commands should
+ * be applied. Once the 100µs delay has been satisfied with at least one
+ * COMMAND INHIBIT or NOP command having been applied, a PRECHARGE command
+ * should be applied. All banks must then be precharged, thereby placing
+ * the device in the all banks idle state.
+ *
+ * "Once in the idle state, two AUTO REFRESH cycles must be performed. After
+ * the AUTO REFRESH cycles are complete, the SDRAM is ready for mode
+ * register programming.
+ *
+ * "Because the mode register will power up in an unknown state, it should
+ * be loaded prior to applying any operational command."
+ *
+ * The JEDEC recommendation for initializing SDRAM is:
+ *
+ * APPLY POWER (Vdd/Vddq equally, and CLK is stable)
+ * Wait 200uS
+ * PRECHARGE all
+ * 8 AUTO REFRESH COMMANDS
+ * LOAD MODE REGISTER
+ * SDRAM is ready for operation
+ *
+ * The Micron SDRAM parts will work fine with the JEDEC sequence, but also
+ * allow for a quicker init sequence of:
+ *
+ * APPLY POWER (Vdd/Vddq equally, and CLK is stable)
+ * Wait at least 100uS (during which time start applying and
+ * continue applying NOP or COMMAND INHIBIT)
+ * PRECHARGE all
+ * 2 AUTO REFRESH COMMANDS (min requirement, more than 2 is also ok)

+ * 4. The handle returned by up_spiinitialize() may then be used to bind the
