Address edge case for stale PSCI CPU data in cache
There is a theoretical edge case during CPU_ON where the cache
may contain stale data for the target CPU data - this can occur
under the following conditions:
- the target CPU is in another cluster from the current
- the target CPU was the last CPU to shutdown on its cluster
- the cluster was removed from coherency as part of the CPU shutdown
In this case the cache maintenace that was performed as part of the
target CPUs shutdown was not seen by the current CPU's cluster. And
so the cache may contain stale data for the target CPU.
This patch adds a cache maintenance operation (flush) for the
cache-line containing the target CPU data - this ensures that the
target CPU data is read from main memory.

In a previous patch, the xlat_ctx_t type has been made public.
This patch now makes the *_ctx() APIs public.
Each API now has a *_ctx() variant. Most of them were already implemented

Now that all these APIs are public, there's no good reason for splitting
them accross 2 files (xlat_tables_internal.c and xlat_tables_common.c).
Therefore, this patch moves all code into xlat_tables_internal.c and
removes xlat_tables_common.c. It removes it from the library's makefile
as well.
This last change introduces a compatibility break for platform ports
that specifically include the xlat_tables_common.c file instead of
including the library's Makefile. The UniPhier platform makefile has
been updated to now omit this file from the list of source files.
The prototype of mmap_add_region_ctx() has been slightly changed. The
mmap_region_t passed in argument needs to be constant because it gets
called from map_add(), which receives a constant region. The former
implementation of mmap_add() used to cast the const qualifier away,
which is not a good practice.
Also remove init_xlation_table(), which was a sub-function of

init_xlat_tables_ctx()). Both names were too similar, which was

After disconnect Jumper pin 1-2 in J15 header, the signal VBUS_DET is to
be pulled down to low level. This will assert the interrupt signal in
PMIC and trigger IRQ in GIC; the asserted signal from VBUS_DET is level
triggered and kernel reports the warning for unhooked interrupt handling;
and VBUS_DET stays with low level, this triggers IRQ storm in kernel.
This patch is to disable interrupt for VBUS_DET in PMIC, this can
dismiss the verbose log and IRQ storm after kernel booting.

xlat lib v2: Export translation context as an opaque type
At the moment, the translation context type (xlat_ctx_t) is a private
type reserved for the internal usage of the translation table library.
All exported APIs (implemented in xlat_tables_common.c) are wrappers
over the internal implementations that use such a translation context.
These wrappers unconditionally pass the current translation context
representing the memory mappings of the executing BL image. This means
that the caller has no control over which translation context the
library functions act on.
As a first step to make this code more flexible, this patch exports
the 'xlat_ctx_t' type. Note that, although the declaration of this type
is now public, its definition stays private. A macro is introduced to
statically allocate and initialize such a translation context.
The library now internally uses this macro to allocate the default
translation context for the running BL image.

xlat lib: Reorganize architectural defs
Move the header files that provide translation tables architectural
definitions from the library v2 source files to the library include
directory. This allows to share these definitions between both
versions (v1 and v2) of the library.
Create a new header file that includes the AArch32 or AArch64
definitions based on the AARCH32 build flag, so that the library user
doesn't have to worry about handling it on their side.
Also repurpose some of the definitions the header files provide to
concentrate on the things that differ between AArch32 and AArch64.
As a result they now contain the following information:
- the first table level that allows block descriptors;
- the architectural limits of the virtual address space;
- the initial lookup level to cover the entire address space.
Additionally, move the XLAT_TABLE_LEVEL_MIN macro from
xlat_tables_defs.h to the AArch32/AArch64 architectural definitions.
This new organisation eliminates duplicated information in the AArch32
and AArch64 versions. It also decouples these architectural files from
any platform-specific information. Previously, they were dependent on
the address space size, which is platform-specific.
Finally, for the v2 of the library, move the compatibility code for
ADDR_SPACE_SIZE into a C file as it is not needed outside of this
file. For v1, this code hasn't been changed and stays in a header
file because it's needed by several files.

This patch updates the user guide documentation to reflect the version of
the Foundation, AEM and Cortex Models that Trusted Firmware has been
tested against.

rockchip: implement hdcp key decryption feature for rk3399
Decrypt device private keys which transfer from kernel, then stuff it to
DP controller. So that DP driver could start HDCP authentication in
kernel.

rockchip/rk3399: fixes the typo and the WARNINGS during suspend/resume
This patch fixes the two things as follows:
1) rk3399_flash_l2_b" seems to be a typo. That's "flush", not "flash".
2) fixes the warnings log.
We always hit the warnings thing during the suspend, as below log:
..
[ 51.022334] CPU5: shutdown
[ 51.025069] psci: CPU5 killed.
INFO: sdram_params->ddr_freq =
928000000
WARNING: rk3399_flash_l2_b:reg
28830380,wait
When the L2 completes the clean and invalidate sequence, it asserts the
L2FLUSHDONE signal. The SoC can now deassert L2FLUSHREQ signal and then
the L2 deasserts L2FLUSHDONE.
Then, a loop without a delay isn't really great to measure time. We should
probably add a udelay(10) or so in there and then maybe replace the WARN()
after the loop. In the actual tests, the L2 cache will take ~4ms by
default for big cluster.
In the real world that give 10ms for the enough margin, like the
ddr/cpu/cci frequency and other factors that will affect it.
