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.

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.

This Linaro release updates just the binaries:
Linaro binaries upgraded 16.12 --> 17.01
The toolchain remains at 5.3-2015.05 (gcc 5.3) for both AArch64
and AArch32.
The ARM TF codebase has been tested against these new binaries. This patch
updates the User Guide to reflect that the 17.01 release is now a supported
Linaro Release.

The behaviour of assert() now depends on the value of the new optional
platform define `PLAT_LOG_LEVEL_ASSERT`. This defaults to `LOG_LEVEL` if
not defined by the platform.
- If `PLAT_LOG_LEVEL_ASSERT` >= `LOG_LEVEL_VERBOSE`, it prints the file
name, line and asserted expression.
- If `PLAT_LOG_LEVEL_ASSERT` >= `LOG_LEVEL_INFO`, it prints the file
name and line.
- If not, it doesn't print anything.
Note the old behaviour was to print the function name whereas now it
prints the file name. This reduces memory usage because the file name is
shared between all assert calls in a given file. Also, the default
behaviour in debug builds is to no longer print the asserted expression,
greatly reducing the string usage.
For FVP debug builds this change saves approximately:

This patch adds `TRUSTED_BOARD_BOOT` support for AArch32 mode.
To build this patch the "mbedtls/include/mbedtls/bignum.h"
needs to be modified to remove `#define MBEDTLS_HAVE_UDBL`
when `MBEDTLS_HAVE_INT32` is defined. This is a workaround
for "https://github.com/ARMmbed/mbedtls/issues/708"

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.

The current SMC context data structure `smc_ctx_t` and related helpers are
optimized for case when SMC call does not result in world switch. This was
the case for SP_MIN and BL1 cold boot flow. But the firmware update usecase
requires world switch as a result of SMC and the current SMC context helpers
were not helping very much in this regard. Therefore this patch does the
following changes to improve this:
1. Add monitor stack pointer, `spmon` to `smc_ctx_t`
The C Runtime stack pointer in monitor mode, `sp_mon` is added to the
SMC context, and the `smc_ctx_t` pointer is cached in `sp_mon` prior
to exit from Monitor mode. This makes is easier to retrieve the
context when the next SMC call happens. As a result of this change,
the SMC context helpers no longer depend on the stack to save and
restore the register.
This aligns it with the context save and restore mechanism in AArch64.
2. Add SCR in `smc_ctx_t`
Adding the SCR register to `smc_ctx_t` makes it easier to manage this
register state when switching between non secure and secure world as a
result of an SMC call.
