+ * WFI Flags for sleep code control
+ *
+ * These flags allow PM code to exclude certain operations from happening
+ * in the low level ASM code found in sleep33xx.S and sleep43xx.S
+ *
+ * WFI_FLAG_FLUSH_CACHE: Flush the ARM caches and disable caching. Only
+ *                       needed when MPU will lose context.
+ * WFI_FLAG_SELF_REFRESH: Let EMIF place DDR memory into self-refresh and
+ *                        disable EMIF.
+ * WFI_FLAG_SAVE_EMIF: Save context of all EMIF registers and restore in
+ *                     resume path. Only needed if PER domain loses context
+ *                     and must also have WFI_FLAG_SELF_REFRESH set.
+ * WFI_FLAG_WAKE_M3: Disable MPU clock or clockdomain to cause wkup_m3 to
+ *                   execute when WFI instruction executes.
+ * WFI_FLAG_RTC_ONLY: Configure the RTC to enter RTC+DDR mode.
