+ * This function creates a "TO-DO list" (operations) for the sp code.

+ * 1. Transfer: Issue DMA transfer request for copying grid cells from DDR to
+ *    accelerator space (NOTE that this space is limited) associated data:
+ *    DDR address + accelerator's config set index(acc's address).
+ *
+ * 2. Issue "Process Lines Command" to shd accelerator
+ *    associated data: #lines + which config set to use (actually, accelerator
+ *    will use x AND (x+1)%num_of_sets - NOTE that this implies the restriction
+ *    of not touching config sets x & (x+1)%num_of_sets when process_lines(x)
+ *    is active).
+ *
+ * Basically there are 2 types of operations "chunks":
+ * 1. "initial chunk": Initially, we do as much transfers as we can (and need)
+ *    [0 - max sets(3) ] followed by 1 or 2 "process lines" operations.
+ *
+ * 2. "regular chunk" - 1 transfer followed by 1 process line operation.
+ *    (in some cases we might need additional transfer ate the last chunk).
+ *
+ * for some case:
+ * --> init
+ *	tr (0)
+ *	tr (1)
+ *	tr (2)
+ *	pl (0)
+ *	pl (1)
