This patch adds functions to save and restore GICv3 ITS registers during
system suspend. Please note that the power management of GIC ITS is
implementation defined. These functions only implements the
architectural part of the ITS power management and they do not restore
memory structures or register content required to support ITS. Even if
the ITS implementation stores structures in memory, an implementation
defined power down sequence is likely to be required to flush some
internal ITS caches to memory. If such implementation defined sequence
is not followed, the platform must ensure that the ITS is not power
gated during system suspend.

During system suspend, the GICv3 Distributor and Redistributor context
can be lost due to power gating of the system power domain. This means
that the GICv3 context needs to be saved prior to system suspend and
restored on wakeup. Currently the consensus is that the Firmware should
be in charge of this. See tf-issues#464 for more details.
This patch introduces helper APIs in the GICv3 driver to save and
restore the Distributor and Redistributor contexts. The GICv3 ITS
context is not considered in this patch because the specification says
that the details of ITS power management is implementation-defined.
These APIs are expected to be appropriately invoked by the platform
layer during system suspend.
Fixes ARM-software/tf-issues#464

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 patch enables choice of RSA version at run time to be used for
generating signatures by the cert_tool. The RSA PSS as defined in
PKCS#1 v2.1 becomes the default version and this patch enables to specify
the RSA PKCS#1 v1.5 algorithm to `cert_create` through the command line
-a option. Also, the build option `KEY_ALG` can be used to pass this
option from the build system. Please note that RSA PSS is mandated
by Trusted Board Boot requirements (TBBR) and legacy RSA support is
being added for compatibility reasons.

The `KEY_ALG` variable is used to select the algorithm for key
generation by `cert_create` tool for signing the certificates. This
variable was previously undocumented and did not have a global default
value. This patch corrects this and also adds changes to derive the
value of `TF_MBEDTLS_KEY_ALG` based on `KEY_ALG` if it not set by the
platform. The corresponding assignment of these variables are also now
removed from the `arm_common.mk` makefile.

The current build system and driver requires the CCI product to be
specified at build time. The device constraints can be determined at run
time from its ID registers, obviating the need for specifying them
ahead.
This patch adds changes to identify and validate CCI at run time. Some
global variables are renamed to be in line with the rest of the code
base.
The build option ARM_CCI_PRODUCT_ID is now removed, and user guide is
updated.

This patch adds a crypto driver which utilizes the ARM® TrustZone®
CryptoCell-712 to verify signature and hash during Trusted Board Boot. Along
with this driver, the CryptoCell SBROM library is required to successfully
build the BL image. The path to this library is specified via
the `CCSBROM_LIB_PATH` variable. Please note that, mbedTLS is still required
to do the X509 certificate ASN.1 parsing and CryptoCell is only utilized for
signature and hash verification.

mbedtls: Don't use tf_snprintf if option not defined
|
|
If `MBEDTLS_PLATFORM_SNPRINTF_ALT` isn't used, the function
`mbedtls_platform_set_snprintf()` isn't defined.
In case a platform uses a different mbed TLS configuration file than
the one provided by the Trusted Firmware, and it doesn't define the
mentioned build option, this will result in a build error.
This patch modifies the initialization code so that
`mbedtls_platform_set_snprintf()` is only used if
`MBEDTLS_PLATFORM_SNPRINTF_ALT` is defined, allowing platforms to use
it or not depending on their needs.

ARM GIC-600 IP complies with ARM GICv3 architecture, but among others,
implements a power control register in the Redistributor frame. This
register must be programmed to mark the frame as powered on, before
accessing other registers in the frame. Rest of initialization sequence
remains the same.
The driver provides APIs for Redistributor power management, and
overrides those in the generic GICv3 driver. The driver data is shared
between generic GICv3 driver and that of GIC-600.
For FVP platform, the GIC-600 driver is chosen when FVP_USE_GIC_DRIVER
is set to FVP_GIC600. Also update user guide.

mbedtls: Define optimized mbed TLS heap size
|
|
mbed TLS provides the debug API `mbedtls_memory_buffer_alloc_status()`
to analyse the RAM usage of the library.
When RSA is selected as algorithm, the maximum heap usage in FVP and
Juno has been determined empirically to be approximately 5.5 KiB.
However, The default heap size used when RSA is selected is 8 KiB.
This patch reduces the buffer from 8 KiB to 6 KiB so that the BSS
sections of both BL1 and BL2 are 2 KiB smaller when the firmware is
compiled with TBB support.

There're eight LUNs in UFS device. The UFS driver only provides

since user may want to access different LUNs.

Reduce code size when building with Trusted Board Boot enabled
|
|
The Trusted Firmware uses a subset of the APIs provided by mbed TLS.
This subset internally uses `snprintf`, but the only format specifier
used is '%d', which is supported by `tf_snprintf`.
This patch makes mbed TLS use `tf_snprintf` instead of `snprintf`,
saving 3 KB in both debug and release builds when TBBR is enabled.

Platforms aligned with TBBR are supposed to use their own OIDs, but
defining the same macros with different OIDs does not provide any
value (at least technically).
For easier use of TBBR, this commit allows platforms to reuse the OIDs
obtained by ARM Ltd. This will be useful for non-ARM vendors that
do not need their own extension fields in their certificate files.
The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h
Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by
defining USE_TBBR_DEFS as 1. USE_TBBR_DEFS is 0 by default to keep the
backward compatibility.
For clarification, I inserted a blank line between headers from the
include/ directory (#include <...>) and ones from a local directory
(#include "..." ).

An earlier patch (arm-trusted-firmware#874) migrated MBEDTLS_ suffixed
macros to have a TBBR_ suffix to avoid any potential clash with future
mbedtls macros.
But on reflection the TBBR_ suffix could be confusing as the macros
are used to drive TF-specific configuration of mbedtls. As such
this patch migrates these macros from TBBR_suffix to TF_MBEDTLS_
suffix which more accurately conveys their use.

This patch removes the code that touched UART_FCR, from
console_core_putc(). The check for whether transmit FIFO is
full is sufficient before writing to UART TX FIFO. In fact
setting UARTFCR_TXCLR immediately after a byte is written to
FIFO might even result in loss of that byte, if UART hasn't
sent that byte out yet.

C files shouldn't be included into others. This file only contains some
macros and functions that can be made `static inline`, so it is ok to
convert it into a header file.
This is the only occurrence of a C file being included in another one in
the codebase instead of using a header, other occurrences are a way of
achieving backwards-compatibility.
Functions therein have been qualified as `inline`.

These macros are not part of mbed TLS so they should not be prefixed
with `MBEDTLS_` to avoid potential collision in the future. Use the
