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.

These errata are only applicable to AArch64 state. See the errata notice
for more details:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.epm048406/index.html
Introduce the build options ERRATA_A53_835769 and ERRATA_A53_843419.
Enable both of them for Juno.
Apply the 835769 workaround as following:
* Compile with -mfix-cortex-a53-835769
* Link with --fix-cortex-a53-835769
Apply the 843419 workaround as following:
* Link with --fix-cortex-a53-843419
The erratum 843419 workaround can lead the linker to create new sections
suffixed with "*.stub*" and 4KB aligned. The erratum 835769 can lead the
linker to create new "*.stub" sections with no particular alignment.
Also add support for LDFLAGS_aarch32 and LDFLAGS_aarch64 in Makefile for
architecture-specific linker options.

TLBI instructions for monitor mode won't have the desired effect under
specific circumstances in Cortex-A57 r0p0. The workaround is to
execute DSB and TLBI twice each time.
Even though this errata is only needed in r0p0, the current errata
framework is not prepared to apply run-time workarounds. The current one
is always applied if compiled in, regardless of the CPU or its revision.
The `DSB` instruction used when initializing the translation tables has
been changed to `DSB ISH` as an optimization and to be consistent with
the barriers used for the workaround.
NOTE: This workaround is present in AArch64 TF and already enabled by
default on Juno.

SPE is only supported in non-secure state. Accesses to SPE specific
registers from SEL1 will trap to EL3. During a world switch, before
`TTBR` is modified the SPE profiling buffers are drained. This is to
avoid a potential invalid memory access in SEL1.
SPE is architecturally specified only for AArch64.

This patch updates the el3_arch_init_common macro so that it fully
initialises essential control registers rather then relying on hardware
to set the reset values.
The context management functions are also updated to fully initialise
the appropriate control registers when initialising the non-secure and
secure context structures and when preparing to leave EL3 for a lower
EL.
This gives better alignement with the ARM ARM which states that software
must initialise RES0 and RES1 fields with 0 / 1.
This patch also corrects the following typos:
"NASCR definitions" -> "NSACR definitions"

This patch fixes the following issues in Firmware Update (FWU) code:
1. The FWU layer maintains a list of loaded image ids and
while checking for image overlaps, INVALID_IMAGE_IDs were not
skipped. The patch now adds code to skip INVALID_IMAGE_IDs.
2. While resetting the state corresponding to an image, the code
now resets the memory used by the image only if the image were
copied previously via IMAGE_COPY smc. This prevents the invalid
zeroing of image memory which are not copied but are directly
authenticated via IMAGE_AUTH smc.

Currently, ROTPK_NOT_DEPLOYED flag is set in plat_get_rotpk_info().
It is up to users how to retrieve ROTPK if the ROT verification is
desired. This is not nice.
This commit improves plat_get_rotpk_info() implementation and automates
the ROTPK deployment. UniPhier platform has no ROTPK storage, so it
should be embedded in BL1/BL2, like ARM_ROTPK_LOCATION=devel_rsa case.
This makes sense because UniPhier platform implements its internal ROM
i.e. BL1 is used as updatable pseudo ROM.
Things work like this:
- ROT_KEY (default: $(BUILD_PLAT)/rot_key.pem) is created if missing.
Users can override ROT_KEY from the command line if they want to
use a specific ROT key.
- ROTPK_HASH is generated based on ROT_KEY.
- ROTPK_HASH is included by uniphier_rotpk.S and compiled into BL1/BL2.
- ROT_KEY is input to cert_create tool.

In CPU off callback function, the old code uses the function
hisi_test_pwrdn_allcores() to check if all CPUs in cluster have been
powered off and if it's valid then power off the whole cluster. But the
function hisi_test_pwrdn_allcores() only maintains the different power
states only for CPU suspend/resume flow, so it cannot return correct
states for CPU on/off flow.
This patch is to change use hisi_test_cpu_down() to check if all CPUs
have been powered off, so that can power off the whole cluster properly
when all CPUs in cluster have been hotplugged off.

The ARM_PLAT_MT bit enables the support for MT bit in
MPIDR format. This means that the level 0 affinity
represents the thread and CPU / Cluster levels are
at affinity level 1 and 2 respectively.
This was not catered for in the scpi 'css_scp_get_power_state, API.
Since the SCPI driver can only cater for single threaded CPUs,
this patch fixes the problem by catering for this shift by
effectively ignoring the Thread (level 0) affinity level.
