The IPI hardware is secure and managed by ATF, nevertheless we deliver

We have do something for clocks gate.

Fox example as the below:

resume:

SO, add the plls_suspend_prepare() and plls_resume_finish() are not
necessary to S2R, that will save S2R time if remove them.

Caesar Wang a14e091621 rockchip: disable watchdog during suspend
The CA53 and CM0 WDT clock gating in rk3399 SGRF, and ATF is in charge of
it because the kernel can't touch SGRF.

Basically the WDT didn't stop at suspend time, it just switched from the
24M to the 32k clock. That meant that the WDT would fire if you slept for
long enough. In other word, the watchdog timer over count will increase to
750 (24*1000/32) times.
The RK3399 HW watchdog interval is 21 seconds. When machine enters the
suspend, the watchdog will reset the system after 35.7 (750/21) hours.

BUG=chrome-os-partner:59257
TEST=daisydog checked and set value, powerd_dbus_suspend to verify.

Julius Werner e77ade2887 rockchip: Clean up parent directory creation for M0
The dependencies in the M0 Makefile are not correctly laid out, which
may lead to errors with make -j if the binary target gets evaluated
before the target that creates the directory. In addition, the M0
Makefile just calls mkdir without using the platform-independent macros
from the main ARM TF build system. This patch fixes those issues,
removes some unused (and broken) M0 build targets and merges the two M0
output directories into one (since there's no real point splitting it up
and it creates more hassle).

Caesar Wang 4c127e687f rockchip: close the PD center logic during suspend
The RK3399 supports close the center logic enter power mode,
so we can close PD_CENTER to save more power during suspend.
Therefore, we need to support save/restore the DDR PHY and
controller registers during suspend/resume.

Also, need CL (http://crosreview.com/397399) to check disabling
center logic.

Caesar Wang 7ac520067c rockchip: clear the power mode status via M0
Due to the PMU design, the PMU may not clear the WAKEUP bit after
wakeup, therefore, the state machine at the power mode may enter
the infinite loop during WFI.

There is a solution that we can use the M0 to monitor the WAKEUP
bit and clear it during power mode, then the state machine will be
recovered immediately. Then, the DUT can exit the WFI normally.

  -Refactor the signatures for bl31_early_platform_setup()

   `void *` instead of `bl31_params_t *`.
  -Introduce `plat_arm_bl2_handle_scp_bl2()` to handle
   loading of SCP_BL2 image from BL2.
  -Remove usage of reserve_mem() function from
   `arm_bl1_early_platform_setup()`
  -Extract BL32 & BL33 entrypoint info, from the link list
   passed by BL2, in `arm_bl31_early_platform_setup()`
  -Provides weak definitions for following platform functions:
     plat_get_bl_image_load_info
     plat_get_next_bl_params
     plat_flush_next_bl_params
     bl2_plat_handle_post_image_load
  -Instantiates a descriptor array for ARM platforms
   describing image and entrypoint information for
   `SCP_BL2`, `BL31`, `BL32` and `BL33` images.

All the above changes are conditionally compiled using the
`LOAD_IMAGE_V2` flag.

Filip Drazic b516b7dc5d zynqmp: pm: Call set_wakeup_source for all wake devices on sys-suspend
During system suspend, identify slaves which are configured
as wake sources and call pm_set_wakeup_source API for each of them.

Identifying if device may wake the system is done by checking if any
interrupt of that device is enabled in GICD_ISENABLER when the APU is
about to enter SUSPEND_TO_RAM state. If such interrupt is found,
pm_set_wakeup_source is called with corresponding PM node ID as
argument.

- PM_APU_STATE_CPU_IDLE - processor power down, all memories remain
  on
- PM_APU_STATE_SUSPEND_TO_RAM - all processors powered down, L2$
  powered down, all OCM banks in retention and DDR in

If we don't enable the Schmitt trigger on the 32 kHz clock then systems
won't always resume from suspend properly.  Presumably anything else in
the system that relies on the 32 kHz clock also will have problems
without the Schmitt trigger enabled.

Enable it always since having the 32 kHz clock on GPIO0_A0 isn't
exactly an optional feature, so all boards using rk3399 will need this.

Caesar Wang 0786d68853 rockchip: on rk3399 init the PMU counts at boot; set 24M/32k properly
In a previous change we mistakenly thought that PMU_24M_EN_CFG directly
controlled whether the PMU counts ran off the 32k vs. 24M clock.
Apparently that's not true.  Real logic is now documented in code.

Also in the previous change we mistaknely though that PMU_24M_EN_CFG was
normally supposed to be 1 and we should "restore" it at resume time.
This is a terrible idea and made the system totally unreliable after
resume.  Apparently PMU_24M_EN_CFG should always be 0 with all the
current code and settings.

Let's fix the above two problems.  While we're changing all of this,
let's also:

1. Init at boot time.  Many of these counts are used when the system is
   running normally.  We want the behavior at boot to match the behavior
   after suspend/resume.

2. Init CPU counts to be 1 us.  Although old code was trying to set this
   to 1 ms (1000x slower) at suspend/resume time, we've been testing the
   kernel with 1 us for a long time now.  That's because the kernel (at
   boot time) set these values to 24.  Let's keep at 24 until we know
   that's wrong.

3. Init GPU counts to be 1 us.  Old code wasn't touching the GPU, but as
   documented in comments it makes sense to init here.  Do it.

4. Document the crap out of this code, since the SoC's behavior is
   confusing and poorly documented in the TRM.

5. Increase some stabilization times to 30 ms (from 3 ms).  It's unclear
   that a full 30 ms is needed, but let's be safe for now.

This also inits the counts for the GPU.

(Thanks to Doug's patch that come from https://crosreview.com/372381)

Antonio Nino Diaz 0289970d6c ARM platforms: Define common image sizes
Compile option `ARM_BOARD_OPTIMISE_MMAP` has been renamed to
`ARM_BOARD_OPTIMISE_MEM` because it now applies not only to defines
related to the translation tables but to the image size as well.

The defines `PLAT_ARM_MAX_BL1_RW_SIZE`, `PLAT_ARM_MAX_BL2_SIZE` and
`PLAT_ARM_MAX_BL31_SIZE` have been moved to the file board_arm_def.h.
This way, ARM platforms no longer have to set their own values if
`ARM_BOARD_OPTIMISE_MEM=0` and they can specify optimized values
otherwise. The common sizes have been set to the highest values used
for any of the current build configurations.

This is needed because in some build configurations some images are
running out of space. This way there is a common set of values known
to work for all of them and it can be optimized for each particular
platform if needed.

The space reserved for BL2 when `TRUSTED_BOARD_BOOT=0` has been
increased. This is needed because when memory optimisations are
disabled the values for Juno of `PLAT_ARM_MMAP_ENTRIES` and
`MAX_XLAT_TABLES` are higher. If in this situation the code is
compiled in debug mode and with "-O0", the code won't fit.

This patch moves the PSCI services and BL31 frameworks like context
management and per-cpu data into new library components `PSCI` and
`el3_runtime` respectively. This enables PSCI to be built independently from
BL31. A new `psci_lib.mk` makefile is introduced which adds the relevant
PSCI library sources and gets included by `bl31.mk`. Other changes which
are done as part of this patch are:

* The runtime services framework is now moved to the `common/` folder to
  enable reuse.
* The `asm_macros.S` and `assert_macros.S` helpers are moved to architecture
  specific folder.
* The `plat_psci_common.c` is moved from the `plat/common/aarch64/` folder
  to `plat/common` folder. The original file location now has a stub which
  just includes the file from new location to maintain platform compatibility.

Most of the changes wouldn't affect platform builds as they just involve
changes to the generic bl1.mk and bl31.mk makefiles.

NOTE: THE `plat_psci_common.c` FILE HAS MOVED LOCATION AND THE STUB FILE AT
THE ORIGINAL LOCATION IS NOW DEPRECATED. PLATFORMS SHOULD MODIFY THEIR
MAKEFILES TO INCLUDE THE FILE FROM THE NEW LOCATION.
