- Migrate to bl31_early_platform_setup2().
- Remove references to removed build options.
- Replace zeromem16() by zeromem().
- Use private definition of bl31_params_t.

This is an incomplete migration, the platform doesn't currently compile.

The type `unsigned long` is 32 bit wide in AArch32, but 64 bit wide in
AArch64. This is inconsistent and that's why we avoid using it as per
the Coding Guidelines. This patch changes all `UL` occurrences to `U`
or `ULL` depending on the context so that the size of the constant is
clear.

This problem affected the macro `BIT(nr)`. As long as this macro is used
to fill fields of registers, that's not a problem, since all registers
are 32 bit wide in AArch32 and 64 bit wide in AArch64. However, if the
macro is used to fill the fields of a 64-bit integer, it won't be able
to set the upper 32 bits in AArch32.

By changing the type of this macro to `unsigned long long` the behaviour
is always the same regardless of the architecture, as this type is
64-bit wide in both cases.

Some Tegra platform files have been modified by this patch.

This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions to this change in order to retain
header groupings and where there are headers within #if statements.

Main fixes:

* Use int32_t replace int, use uint32_t replace unsign int [Rule 4.6]
* Added explicit casts (e.g. 0U) to integers in order for them to be
  compatible with whatever operation they're used in [Rule 10.1]
* Force operands of an operator to the same type category [Rule 10.4]
* Fixed assert/if statements conditions to be essentially boolean [Rule 14.4]
* Added curly braces ({}) around if statements in order to
  make them compound [Rule 15.6]
* Convert macros form headers to unsigned ints

This patch modifies the secure IRQ registration process to allow platforms
to specify the target CPUs as well as the owner of the IRQ. IRQs "owned"
by the EL3 would return INTR_TYPE_EL3 whereas those owned by the Trusted
OS would return INTR_TYPE_S_EL1 as a result.

Tegra chips support multiple FIQ interrupt sources. These interrupts
are enabled in the GICD/GICC interfaces by the tegra_gic driver. A
new FIQ handler would be added in a subsequent change which can be
registered by the platform code.

This patch adds the GIC programming as part of the tegra_gic_setup()
which now takes an array of all the FIQ interrupts to be enabled for
the platform. The Tegra132 and Tegra210 platforms right now do not
register for any FIQ interrupts themselves, but will definitely use
this support in the future.

In order to handle secure/non-secure interrupts, overload the plat_ic_*
functions and copy GIC helper functions from arm_gic.c. Use arm_gic.c
as the reference to add Tegra's GIC helper functions.

Now that Tegra has its own GIC implementation, we have no use for
plat_gic.c and arm_gic.c files.

T210 is the latest chip in the Tegra family of SoCs from NVIDIA. It is an
ARM v8 dual-cluster (A57/A53) SoC, with any one of the clusters being active
at a given point in time.

This patch adds support to boot the Trusted Firmware on T210 SoCs. The patch
also adds support to boot secondary CPUs, enter/exit core power states for
all CPUs in the slow/fast clusters. The support to switch between clusters
is still not available in this patch and would be available later.

This patch adds support for ARM Cortex-A72 processor in the CPU
specific framework.

Change-Id: I5986855fc1b875aadf3eba8c36e989d8a05e5175

This patch adds the initial port of the ARM Trusted Firmware on the Juno
development platform. This port does not support a BL3-2 image or any PSCI APIs
apart from PSCI_VERSION and PSCI_CPU_ON. It enables workarounds for selected
Cortex-A57 (#806969 & #813420) errata and implements the workaround for a Juno
platform errata (Defect id 831273).

Change-Id: Ib3d92df3af53820cfbb2977582ed0d7abf6ef893

This patch adds workarounds for selected errata which affect the Cortex-A57 r0p0
part. Each workaround has a build time flag which should be used by the platform
port to enable or disable the corresponding workaround. The workarounds are
disabled by default. An assertion is raised if the platform enables a workaround
which does not match the CPU revision at runtime.

This patch adds handlers for dumping Cortex-A57 and Cortex-A53 specific register
state to the CPU specific operations framework. The contents of CPUECTLR_EL1 are
dumped currently.

This patch adds CPU core and cluster power down sequences to the CPU specific
operations framework introduced in a earlier patch. Cortex-A53, Cortex-A57 and
generic AEM sequences have been added. The latter is suitable for the
Foundation and Base AEM FVPs. A pointer to each CPU's operations structure is
saved in the per-cpu data so that it can be easily accessed during power down
seqeunces.

An optional platform API has been introduced to allow a platform to disable the
Accelerator Coherency Port (ACP) during a cluster power down sequence. The weak
definition of this function (plat_disable_acp()) does not take any action. It
should be overriden with a strong definition if the ACP is present on a
platform.

* Move TSP platform porting functions to new file:
  include/bl32/tsp/platform_tsp.h.

* Create new TSP_IRQ_SEC_PHY_TIMER definition for use by the generic
  TSP interrupt handling code, instead of depending on the FVP
  specific definition IRQ_SEC_PHY_TIMER.

* Rename TSP platform porting functions from bl32_* to tsp_*, and
  definitions from BL32_* to TSP_*.

* Update generic TSP code to use new platform porting function names
  and definitions.

* Update FVP port accordingly and move all TSP source files to:
  plat/fvp/tsp/.

* Update porting guide with above changes.

Note: THIS CHANGE REQUIRES ALL PLATFORM PORTS OF THE TSP TO
      BE UPDATED

Reduce the number of header files included from other header
files as much as possible without splitting the files. Use forward
declarations where possible. This allows removal of some unnecessary
"#ifndef __ASSEMBLY__" statements.

Also, review the .c and .S files for which header files really need
including and reorder the #include statements alphabetically.
