GCC version 4.8 (and presumably earlier) warn when non-standard types are
used for bitfield definitions when -pedantic is enabled. This prevents TF
from being built with such toolchains, since -Werror -pedantic options are
used.
gcc-4.9 removed this warning; -pedantic is intended to cause gcc to emit a
warning in all cases required by the standard, but the standard does not
require a warning in this case.

This patch adds flexibility to the code to initialise multiple SMMU
devices. The base address macro name has been changed to make it
explicit that we support multiple SMMUs.

This patch enables the 'xlat_table_v2' library for the Tegra Memory
Controller driver. This library allows us to dynamically map/unmap
memory regions, with MMU enabled.
The Memory Controller driver maps/unmaps non-overlapping Video Memory
region, to clean it of any secure contents, before it resizes the
region.

This patch makes the default implementation of plat_core_pos_by_mpidr()
as weakly linked, so that platforms can override it with their own.
Tegra186, for one, does not have CPU IDs 2 and 3, so it has its own
implementation of plat_core_pos_by_mpidr().

This patch adds a new SMC function ID to read the refclk and coreclk
clock counter values from the Activity Monitor. The non-secure world
requires this information to calculate the CPU's frequency.
Formula: "freq = (delta_coreclk / delta_refclk) * refclk_freq"
The following CPU registers have to be set by the non-secure driver
before issuing the SMC:
X1 = MPIDR of the target core
X2 = MIDR of the target core

Remove stream ID overrides for AON. AON drives its own stream ID when
accesing IOVA memory. However, it needs to use a physical stream ID when
accesing GSC memory. Overriding stream ids prevents AON from accessing
GSC memory, so remove them to allow AON to access GSCs.

When entering C7, ATF disables caches and flushes the L1 cache. However,
wake_time[cpu] can still remain in the L2 cache, causing later reads to it
to fetch from DRAM. This will read stale values.
Fix this by aligning wake_time[cpu] to cache lines, and explicitly cleaning it
before disabling caches.

If SCP_BL2 is passed in from the command line, it is recognized by
make_helpers/tbbr/tbbr_tools.mk, and the cert_create tool generates
the corresponding key and content certificates.
On the other hand, the top-level Makefile does not care SCP_BL2, so
the --scp-fw option is not passed to the fiptool. As far as I see
plat/arm/css/common/css_common.mk, it looks like a platform's job to
add $(eval $(call FIP_ADD_IMG,SCP_BL2,--scp-fw)).
We can make the top-level Makefile kind enough to take care of it.
This is useful when we want to have optional SCP_BL2 firmware.
Adjust css_common.mk so that Juno still requires SCP_BL2 by default.

Some header files using the ULL() macro were not directly including
utils.h where the macro definition resides. As a consequence, a linker
script with values using this macro did not see the macro definition
and kept the "ULL(<value>)" call in the preprocessed file, which lead to
link error.
Files using ULL() macro now include utils.h directly.
