Revert "rockchip: Remove unused rockchip_pd_pwr_down_wfi function"

This reverts commit b6dcbf58

.

This function wasn't used when it was removed, but it is needed to
compile the new changes proposed for Rockchip platforms.

Minor makefile fixes

Migrate secure payload dispatchers to new SMC terminology

Fix execute-never permissions in xlat tables libs

Since Issue B (November 2016) of the SMC Calling Convention document
standard SMC calls are renamed to yielding SMC calls to help avoid
confusion with the standard service SMC range, which remains unchanged.

http://infocenter.arm.com/help/topic/com.arm.doc.den0028b/ARM_DEN0028B_SMC_Calling_Convention.pd



A previous patch introduced a new define for yielding SMC call type.
This patch updates the secure payload dispatchers (except the TSPD) to
use this new define and also migrates the code to use the new
terminology.

Some recent changes have added direct use of the echo command without
parameters.  This fails on a Windows shell, because echo without
parameters reports the mode ("ECHO is on").
This is corrected using the ECHO_BLANK_LINE macro already provided
for that purpose.

2 problems were found, but are in one change to avoid submitting a patch
that might fail to build. The problems were:
1.  The macro MAKE_PREREQ_DIR has a minor bug, in that it is capable of
    generating recursive dependencies.
2.  The inclusion of BUILD_DIR in TEMP_OBJ_DIRS left no explicit
    dependency, BUILD_DIR might not exist when subdirectories are
    created by a thread on another CPU.

This fix corrects these with the following changes:
1.  MAKE_PREREQ_DIR does nothing for a direct self dependency.
2.  BUILD_DIR is built using MAKE_PREREQ_DIR.
3.  BUILD_DIR is an explicit prerequisite of all OBJ_DIRS.

Update terminology: standard SMC to yielding SMC

Translation regimes that only support one virtual address space (such as
the ones for EL2 and EL3) can flag memory regions as execute-never by
setting to 1 the XN bit in the Upper Attributes field in the translation
tables descriptors. Translation regimes that support two different
virtual address spaces (such as the one shared by EL1 and EL0) use bits
PXN and UXN instead.

The Trusted Firmware runs at EL3 and EL1, it has to handle translation
tables of both translation regimes, but the previous code handled both
regimes the same way, as if both had only 1 VA range.

When trying to set a descriptor as execute-never it would set the XN
bit correctly in EL3, but it would set the XN bit in EL1 as well. XN is
at the same bit position as UXN, which means that EL0 was being
prevented from executing code at this region, not EL1 as the code
intended. Therefore, the PXN bit was unset to 0 all the time. The result
is that, in AArch64 mode, read-only data sections of BL2 weren't
protected from being executed.

This patch adds support of translation regimes with two virtual address
spaces to both versions of the translation tables library, fixing the
execute-never permissions for translation tables in EL1.

The library currently does not support initializing translation tables
for EL0 software, therefore it does not set/unset the UXN bit. If EL1
software needs to initialize translation tables for EL0 software, it
should use a different library instead.

xlat lib: Don't set mmap_attr_t enum to be -1

-1 is not a defined mmap_attr_t type. Instead of using invalid enum
types, we can either choose to define a INVALID type OR handle the
condition specifically.

Since the usage of mmap_region_attr is limited, it is easier to just
handle the error condition specifically and return 0 or -1 depending
on success or fail.

This patch implements the handler to calculate the cluster and
system power states for the Tegra210 SoC. The power states
returned by this handler are used by the PSCI library to decide
cache maintenance operations - cluster v cpu.

This patch fixes the logic used to calculate the end of NS memory
aperture. The functions allows zero sized NS apertures as that is
a valid requirement for some use cases. e.g. VPR resize.

The video memory carveout has to be re-sized depending on the Video
content. This requires the NS world to send us new base/size values.
Before setting up the new region, we must zero out the previous memory
region, so that the video frames are not leaked to the outside world.

This patch adds the logic to zero out the previous memory carveout
region.

Earlier, we were setting "System Suspend" as the power state for all system
states. This caused incorrect system state during a cluster power down.

This patch fixes this anomaly and sets the correct power state during a
cluster/system power down.

utils.h is included in various header files for the defines in it.
Some of the other header files only contain defines.  This allows the
header files to be shared between host and target builds for shared defines.

Recently types.h has been included in utils.h as well as some function
prototypes.

Because of the inclusion of types.h conflicts exist building host tools
abd these header files now.  To solve this problem,
move the defines to utils_def.h and have this included by utils.h and
change header files to only include utils_def.h and not pick up the new
types.h being introduced.
