+/*
+ * This function creates a "TO-DO list" (operations) for the sp code.
+ *
+ * There are 2 types of operations:
+ * 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)
+ * --> ack (0)
+ * tr (3)
+ * pl (2)
+ * --> ack (1)
+ * pl (3)
+ * --> ack (2)
+ * do nothing
+ * --> ack (3)
