For rk3399, the L2ACTLR[14] is 0 by default, as ACE CCI-500 doesn't
support WriteEvict. and you will hit the condition L2ACTLR[3] with 0,
as the Evict transactions should propagate to CCI-500 since it has
snoop filters.

Maybe this erratum applies to all Cortex-A53 cores so far, especially
if RK3399's A53 is a r0p4. we should enable it to avoid data corruption,

For some reason, HDCP key decrytion can't open source in ATF, so we
build it as hdcp.bin. Besides declare the handler for decrypting.

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

These source file definitions should be defined in generic
Makefiles so that all platforms can benefit. Ensure that the
symbols are properly marked as weak so they can be overridden
by platforms.

NOTE: This change is a potential compatibility break for
non-upstream platforms.

The goal is that make clear the secure and SoC codes. Now cleaning them
will help secure code extensions for RK3399 in the future.

We used dcf do ddr frequency scaling, but we just include a dcf
binary, it hard to maintain later, we have M0 compile flow in ATF,
and M0 can also work for ddr frequency scaling, so let's use it.

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).

This patch intend to support save the registers of the DDR controller
and PHY before suspend, and restore them after resume.

This renames dram.c and dram.h to dfs.c and dfs.h respectively. This
is to make room for common functionality between frequency scaling and
suspend code for the DRAM in a pair of common files named dram.c and
dram.h. It also removes a duplicate enum definition from
dram_spec_timing.h

This CL supports add M0 source code to built into the bl31.bin, the
goal is that we can load the M0 code binary into SRAM and execute it.

We need the M0 help us to clean the power_mode_en bit during the AP
PMU enter the state machine with interrupt, and avoid to the AP can
not exit the loop forever.

Add the common extra.ld.S and customized rk3399.ld.S to extend
to more features for different platforms.
For example, we can add SRAM section and specific address to
load there if we need it, and the common bl31.ld.S not need to
be modified.

Therefore, we can remove the unused codes which copying explicitly
from the function pmusram_prepare(). It looks like more clear.

This patch updates some things for rk3399, as following:

1) Add the new file to handle the pwm. (e.g. the pwm regulator)
Make sure that good deal with the pwm related things.
Also, remove some pwm setting for pmu.c.

2) Set the plls slow mode and bypass in suspend, and restore them.

Software executing in the normal world and in the trusted world at
exception levels lower than EL3 will request runtime services using the
SMC instruction.

See the documentation here:
https://github.com/ARM-software/arm-trusted-firmware/blob/master/docs/
rt-svc-writers-guide.md

This to be implemented as an EL3 Runtime Service in rockchip BL31
platform port, using the "SiP Service Call" range as specified in the
SMC Calling Convention.
This doesn't support any SMC yet, we will support it in later.

We add plat parameter structs to support BL2 to pass variable-length,
variable-type parameters to BL31. The parameters are structured as a
link list. During bl31 setup time, we travse the list to process each
parameter. throuth this way, we can get the reset or power off gpio
parameter, and do hardware control in BL31. This structure also can
pass other parameter to BL31 in future.

There are 5 groups of GPIO (GPIO0~GPIO4), totally have 122 GPIOs
on rk3399 platform.
The pull direction(pullup or pulldown) for all of GPIOs are
software-programmable.
At the moment, we add the gpio basic driver since reset or power off
the devices from gpio configuration for BL31.

Use the generic delay timer instead of having a specific platform
file for configuring it.

as it is not specific to AArch64.

This patch adds to support the RK3368 and RK3399 SoCs.

RK3368/RK3399 is one of the Rockchip family SoCs, which is an
multi-cores ARM SoCs.

This patch adds support to boot the Trusted Firmware on RK3368/RK3399
SoCs, and adds support to boot secondary CPUs, enter/exit core
power states for all CPUs in the slow/fast clusters.

This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs)
* Support arm gicv2 & gicv3.
* Boot up multi-cores CPU.
* Add generic CPU helper functions.
* Support suspend/resume.
* Add system_off & system_reset implementation.
* Add delay timer platform implementation.
* Support the new porting interface for the PSCI implementation.
