Lin Huang bc5c30073e rockchip: add pmusram section
the function pmu_cpuon_entrypoint() need to run in the pmusram,
we just copy bin file to pmusram before, now we add pmusram section
and link pmu_cpuon_entrypoint() to pmusram directly

We found that the DUT will be hanged if we don't set the bit_1 of the

Soren Brinkmann aa2345e917 rk3399: Add CFI debug information to SRAM functions
Commit b91d935fee
("Add CFI debug frame information for ASM functions") modifies the
assembly macros 'func' and 'endfunc' to include CFI debug frame
information.

The rockchip platform uses a custom version of the 'func' macro with the
common 'endfunc' macro. The custom macro wasn't updated in
b91d935fee resulting in the following
build error:
  plat/rockchip/rk3399/drivers/pmu/plat_pmu_macros.S: Assembler messages:
  plat/rockchip/rk3399/drivers/pmu/plat_pmu_macros.S:155: Error: .cfi_endproc without corresponding .cfi_startproc
  Makefile:532: recipe for target 'build/rk3399/release/bl31/plat_helpers.o' failed
  make: *** [build/rk3399/release/bl31/plat_helpers.o] Error 1

Fixing this by updating the sram_func macro in the rk3399 port.

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.

TEST=daisydog checked and set value, powerd_dbus_suspend to verify.

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.

cluster enter powering off mode.

Caesar Wang 9d5aee2b1f rockchip: on rk3399 enable Schmitt trigger on 32 kHz clock
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)
