16 * WFI Flags for sleep code control

18 * These flags allow PM code to exclude certain operations from happening
19 * in the low level ASM code found in sleep33xx.S and sleep43xx.S
20 *
21 * WFI_FLAG_FLUSH_CACHE: Flush the ARM caches and disable caching. Only
22 * needed when MPU will lose context.
23 * WFI_FLAG_SELF_REFRESH: Let EMIF place DDR memory into self-refresh and
24 * disable EMIF.
25 * WFI_FLAG_SAVE_EMIF: Save context of all EMIF registers and restore in
26 * resume path. Only needed if PER domain loses context
27 * and must also have WFI_FLAG_SELF_REFRESH set.
28 * WFI_FLAG_WAKE_M3: Disable MPU clock or clockdomain to cause wkup_m3 to
29 * execute when WFI instruction executes.
30 * WFI_FLAG_RTC_ONLY: Configure the RTC to enter RTC+DDR mode.
