In case of an OTP-CLOSED STM32MP15xx system, the CPU core 1 cannot be
released from endless loop in BootROM only by populating TAMP BKPxR 4
and 5 with magic and branch address and sending SGI0 interrupt from
core 0 to core 1 twice. TAMP_SMCR BKP..PROT fields must be initialized
as well to release the core 1 from endless loop during the second SGI0
handling on core 1. Initialize TAMP_SMCR to protect the first 32 backup
registers, the ones which contain the core 1 magic, branch address and
boot information.
This requirement seems to be undocumented, therefore it was necessary
to trace and analyze the STM32MP15xx BootROM using OpenOCD and objdump.
Ultimately, it turns out that a certain BootROM function reads out the
TAMP_SMCR register and tests whether the BKP..PROT fields are non-zero.
If they are zero, the BootROM code again waits for SGI0 using WFI, else
the execution moves forward until it reaches handoff to the TAMP BKPxR 5
branch address.
This fixes CPU core 1 release using U-Boot PSCI implementation on an
OTP-CLOSED system, i.e. system with fuse 0 bit 6 set.

SoC revision is only accessible via DBUMCU IDC register,
which requires BSEC.DENABLE DBGSWENABLE bit to be set to
make the register accessible, otherwise an access to the
register triggers bus fault. As BSEC.DBGSWENABLE is zero
in case of an OTP-CLOSED system, do NOT set DBGSWENABLE
bit as this might open a brief window for timing attacks.
Instead, report that this system is OTP-CLOSED and do not
report any SoC revision to avoid confusing users. Use an
SEC/C abbreviation to avoid growing SOC_NAME_SIZE .

In case the system has resumed successfully, the PSCI suspend resume
code has to jump to the 'ep' successful resume entry point code path,
otherwise the code has to jump to content of the LR register, which
points to failed resume code path.
To implement this distinction, rewrite LR register stored on stack
with 'ep' value in case of a successful resume, which is really in
every case unless some catastrophic failure occurred during suspend.
Without this change, Linux counts every resume as failed in
/sys/power/suspend_stats/fail

The PWR_MPUCR CSTBYDIS bit is set, therefore the CA cores can never

as it makes little sense to keep it set with CSTBYDIS also set.
This does however fix a problem too. When both PWR_MPUCR and PWR_MCUCR
PDDS bits are set, then the chip enters CStandby state even though the
PWR_MCUCR CSTBYDIS is set. Clearing the PWR_MPUCR PDDS prevents that
from happening.

In case the IWDG is enabled by either U-Boot or Linux, the IWDG can never
be disabled again. That includes low power states, which means that if the
IWDG is enabled, the SoC would reset itself after a while in suspend via
the IWDG. This is not desired behavior.
It is possible to enable IWDG pre-timeout IRQ which is routed into the EXTI,
and use that IRQ to wake the CPU up before the IWDG timeout is reached and
reset is triggered. This pre-timeout IRQ can be used to reload the WDT and
then suspend the CPU again every once in a while.
Implement this functionality for both IWDG1 and IWDG2 by reading out all
the unmasked IRQs, comparing the list with currently pending IRQs in GICv3:
- If any IRQ is pending and it is NOT IWDG1 or IWDG2 pre-timeout IRQ,
wake up and let OS handle the IRQs
- If IWDG1 or IWDG2 IRQ is pending and no other IRQ is pending,
ping the respective IWDG and suspend again
This does not seem to have any adverse impact on power consumption in suspend.
