FreeBSD does not understand #interrupt-map in a device tree. This prevents the
GIC from being set up correctly. This patch removes the #interrupt-map in the
device trees for the Base and Foundation FVPs. This enables correct boot of
FreeBSD on these platforms.

These changes have been tested with FreeBSD and an Ubuntu cloud image
(ubuntu-16.04-server-cloudimg-arm64-uefi1.img) to ensure compatibility with
Linux.

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.

If UFS device is initialized, we could just make it out of
hibernation by UFS_FLAGS_SKIPINIT. And vendor's dirver is always
focus on PHY setting. We could use UFS driver directly if it
exits from hibernation.

There're eight LUNs in UFS device. The UFS driver only provides
the read/write API with LUN. User could define his own read/write
since user may want to access different LUNs.

Only the compiler is switched to ARM Compiler 6.  The assembler and linker
are provided by the GCC toolchain.

ARM Compiler 6 is used to build TF when the base name of the path assigned
to `CC` matches the string 'armclang'.

`CROSS_COMPILE` is still needed and should point to the appropriate
GCC toolchain.

Tested with ARM CC 6.7.

Collect headers shared between TF and host-tools into include/tools_share

This options enables an implementation of SHA-256 that has a smaller
code footprint (~1.6 KB less) but is also ~30% slower. For ARM
platforms, code size is currently considered more important than
execution speed in the mbed TLS crypto module.

Added a small note about this option to the documentation of the
authentication framework.

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.

This is a reduced version of `snprintf` that only supports formats '%d',
'%i' and '%u'. It can be used when the full `snprintf` is not needed in
order to save memory. If it finds an unknown format specifier, it
prints an error message and panics.

The header tbbr_oid.h contains OIDs obtained by ARM Ltd.
so there is no good reason to use platform_oid.h
Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

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 "..." ).

Some header files need to be shared between TF and host programs.
For fiptool, two headers are copied to the tools/fiptool directory,
but it looks clumsy.

This commit introduces a new directory, include/tools_share, which
collects headers that should be shared between TF and host programs.

This will clarify the interface exposed to host tools.  We should
add new headers to this directory only when we really need to do so.

The current assert_boolean does not work with variables assigned with
'=' flavor instead of ':='.

For example,

 FOO = $(BAR)
 BAR := 1

Here, $(value FOO) is evaluated to $(BAR), not 1.  This is not what
we expect.  While I am here, I simplified the implementation.
