If ATF loads OP-TEE, it will pass OP-TEE base
address and size to the u-boot through boot information.
This will help u-boot update device tree accordingly.
Note that u-boot on i.MX 8QxP does not need this information
to configure memory mapping. Query to the SC Firmware
is used instead

This patch adds support for cpuidle with CPU powerdown,
there will be 3 idle states in Linux kernel:
1: wfi;
2: cpu power down;
3: cluster power down.
As Linux kernel needs a broadcast timer for waking up
CPU when whole CLUSTER is powerdown, GPT is adopted as
broadcast timer, and to make the clock & power management
easy for Linux kernel to avoid many workaround/hake in
Linux kernel, TF-A will handle GPT's power & clock management
as well as registers save/restore when suspend/resume.
Also, psci power states are used to determine CORE/CLUSTER/SYSTEM
power state to distinguish CPU idle and SYSTEM suspend which share
same domain_suspend callback.
The SoC IPs register mmap regions are merged into 1 large
section to cover all the SoC IPs register ranges TF-A needs,
this is to save mmap regions and make it simple.

The Trusty OS binary will be installed into
container.img and loaded into 0x84000000.
Due Trusty OS addresss is in 0xfe000000 which
ROM cannot reach, so use ATF to copy it into
the target address.
Mapped the BL32 code into MMU due the Trusty
SPD need to check the code status and decide
the CPU executing mode.
To reserve and protect the memory for secure
world, modify the partition code to keep
BL32 spaces in secure_part.

Using sc_pm_set_cpu_resume API instead of sc_pm_set_cpu_resume_addr
to support random CPU resume for system suspend, as Linux kernel
now supports non CPU0 suspend, we have to specify the CPU ID for
SCFW to wake up when system resume.

With flash_uboot_cm4ddr in imx-mkimage, the m4 code will access ddr.
However after m4 core moved to non-secure partition, the ddr memory
is still in secure partition. Then m4 core will fault.
So postpone moving resources including m4 core, until other resources,
such as memory/pin moved to non-secure partition.

With default configuration, M4 and A35 in one partition, M4 is loaded by ROM.
"err = sc_rm_move_all(ipc_handle, secure_part, os_part, true, true);"
M4 core will first be moved to non-secure OS part, then the resource used
by M4 will be moved to non-secure OS part later. But before the resource be
moved to non-secure OS part, M4 core is still running, so a non-secure M4
core access a secure resource will trigger error in M4 side.
First mark M4 core as non-movable, after all other resoures moved to OS
part, move M4 to OS part. No need to check whether M4 is created a new
partition by SCFW, if a partition already created, the call to mark
M4 as non-removable will fail, because it M4 is in its own partition.

the DBLOG need to be put into low power mode.
GIC need to be power off to save power. before GIC

Not only the resources, but also the memory regions need to assign to
non-secure partition. Otherwise, when the boot partition is secured,
the OS non-secure partition can't access any memory.
This patch currently assign all memory to NS partition, since it is not
isolated, the current secure partition also can access them. In future,
may need to change the regions for reserving some memory in secure
partition for ATF and BL32.
