Siva Durga Prasad Paladugu 96cd17f49d zynqmp: pm: Correct WDT clock database
WDT used by APU is FPD_WDT. FPD WDT clock is controlled by
FPD_SLCR.WDT_CLK_SEL register. Correct the same in WDT clock
database.

As per FPD_SLCR.WDT_CLK_SEL register, there can be only two
parents of WDT clock not three. Fix the same by correcting it's
parents in clock database.

Siva Durga Prasad Paladugu 9a2850e5fa zynqmp: pm: Add IOCTL to set boot health status
Since the MMIO read/write APIs are removed from Linux user space,
Linux cannot directly write to the Global General Storage Register 4
any more to set healthy boot status.

Create an IOCTL to allow Linux to set boot health status.

Siva Durga Prasad Paladugu 7c0b17e34b zynqmp: pm_service: Add support for resetting ULPI transceiver
To make ULPI transceiver work, a HIGH - LOW - HIGH pulse needs
to be given to resetb pin of ULPI chip. In ZYNQMP, this resetb
pin is being driven by BOOT MODE PIN 1. The BOOT MODE PIN's
are controlled by BOOT_PIN_CTRL register present in CRL_APB
address region. Since CRL_APB can be resticted to secure access,
this pin should be controlled by ATF.

This patch adds the support for the same.

Siva Durga Prasad Paladugu 91bf4c5c15 zynqmp: Fix EG/EV detection logic
The vcu disable bit in efuse ipdisable register is valid
only if PL powered up so, consider PL powerup status for
determing EG/EV part. If PL is not powered up, display
EG/EV as a part of string. The PL powerup status will
be filled by pmufw based on PL PROGB status in the
9th bit of version field.This patch also used IPI
to get this info from pmufw instead of directly accessing
the registers. Accessing this info from pmufw using
IPI fixes the issue of PMUFW access denied error for
reading IPDISABLE register.

Naga Sureshkumar Relli 06526c9797 zynqmp: Add RW access to L2ACTLR_EL1 and CPUACTLR_EL1
Arm provided error injection support. To enable this error injection,
we need to set L2DEIEN in L2ACTLR_EL1 register and L1DEIEN in
CPUACTLR_EL1 register.

This is needed for our cortexa53 edac linux driver testing.
These registers need write access from non secure EL1 i.e linux
at the time of setting the above bits.

 - ZYNQMP_ATF_MEM_BASE
 - ZYNQMP_ATF_MEM_SIZE
 - ZYNQMP_BL32_MEM_BASE
 - ZYNQMP_BL32_MEM_SIZE
can be used to freely configure the memory locations used for ATF and
secure payload.

Also, allow setting the BL33 entry point via PRELOADED_BL33_BASE.
