When a platform enables its caches before it accesses the
psci_non_cpu_pd_nodes structure then explicit cache maintenance
is not needed.

The MMU is not disabled in this path, update the comment to
reflect this. Also clarify that both paths call prepare_cpu_pwr_dwn(),
but the second path does stack cache maintenance.

commit 97d5db8c5c reverts an update to the
MMC layer that accompanied the original submission of this MMC driver this
is the right-thing-to-do in terms of the MMC spec.
Unfortunately the reversion also breaks this driver. The issue is the i.MX
controller doesn't want MMC_RSP_48 set for MMC_RESPONSE_R2.
The appropriate place to place that constraint is obviously in
drivers/imx/usdhc/imx_usdhc.c not in the shared MMC codebase. This patch
restores the logic the i.MX controller requires without breaking it for
everyone else.

The "Secure" prefix (S-ELx) is valid only for S-EL0 and S-EL1 but is
meaningless for EL3, since EL3 is always secure. Hence, the "S" prefix
has been removed from wherever it was used as "S-EL3".

In the function, bl1_early_platform_setup in the file
plat/arm/css/sgm/sgm_bl1_setup.c:
plat_config_init();
arm_bl1_early_platform_setup();
The debug messages logged by plat_config_init() are lost because
the console is initialized in the function
arm_bl1_early_platform_setup()
To see the logs of plat_config_init, this fix re-orders above calls
so that the console is initialized before call to plat_config_init.

This way it can be reused by other platforms if needed.
Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.
Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.

Commit 79621f0038 broke sgi575.
It is possible to have a region with 0 as value for the attributes. It
means device memory, read only, secure, executable. This is legitimate
if the code is in flash and the code is executed from there.
This is the case for SGI_MAP_FLASH0_RO, defined in the file
plat/arm/css/sgi/sgi_plat.c.
This problem is solved by checking both size and attributes in xlat v1.
In xlat v2, it is enough to check the granularity, as it can never be 0.

"-s" is a command line option to the make tool, to suppress normal output,
something to the effect of prepending every line with '@' in the Makefile.
However with our V={0|1} support, we now print the shortened command line
output in any case (even with V=1, in addition to the long line!).
Normally -s helps to not miss non-fatal warnings, which tend to scroll out
of the window easily.
Introduce a new Makefile variable ECHO, to control the shortened output.
We only set it in the (current default) V=0 case, and replace every
occurence of "@echo" with that variable.
When the user specifies "-s", we set ECHO to some magic string which
changes the output line into a comment, so the output is suppressed.
Beside suppressing every output for "-s", we also avoid the redundant
short output when compiling with V=1.
This changes the output to:
==========
$ make -s PLAT=.... bl31
Built build/.../release/bl31.bin
==========
$ make PLAT=.... bl31
...
CC lib/libc/strncmp.c
CC lib/libc/strnlen.c

HOSTCC should be used in any of the tools inside the tools/ directory
instead of CC. That way it is possible to override both values from the
command line when building the Trusted Firmware and the tools at the
same time. Also, use HOSTCCFLAGS instead of CFLAGS.
Also, instead of printing the strings CC and LD in the console during
the compilation of the tools, HOSTCC and HOSTLD have to be used for
clarity. This is how it is done in other projects like U-Boot or Linux.

When attempting to compile TF-A with "SPD=something ARCH=aarch32", the
following error message is printed:
Makefile:291: *** recipe commences before first target. Stop.
This is because the call to the error function is indented using a tab
whereas it's not part of a rule's recipe. Replace the tab by spaces.

As these rules depend on non-existing headers as well (likely copy &
pasted from fiptool), they never matched, and the built-in rules were
used. That led to random breakages when e.g. CPPFLAGS was suddenly
evaluated and contained invalid options.
For the stm32image, this reveals that we were relying on the built-in
rules by passing -D_GNU_SOURCE via CPPFLAGS, rather than using CFLAGS as
used in the local rule. Fix that as well.

The BLE is the pre-TF-A boot stage required by Marvell Armada
BootROM for bringing up DRAM and allow the boot image copy to it.
Since this is not a standard boot level and only uses the TF-A
as a build environment, it was introduced out of source tree.
However it turns out that such remote location introduces additional
complexity to the upstream TF-A build process.
In order to simplify the build environment the BLE source folder
is relocated from the external repository to A8K platform directory.
The build documentation is updated accordingly.

Map the initialization code for BL31 to overlap with the memory
required for the secondary cores stack. Once BL31 has been
initialized the memory can be remapped to RW data so that it can
be used for secondary cores stacks. By moving code from .text to
.text.init the size of the BL31 image is decreased by a page.
Split arm_common.ld.S into two linker scripts, one for tzc_dram
(arm_tzc_dram.ld.S) and one for reclaiming initialization code
(arm_reclaim_init.ld.S) so that platforms can chose which memory
regions they wish to include.

Depending on the build flags it is possible that some of the memory
regions mapped in page table setup could have a size of 0. In this
case we simply want to do nothing but still wish to map the other
regions in the array. Therefore we cannot only use size == 0 as
the termination logic for the loop.
Since an attributes field with value 0 means that the region is
device memory, read only, secure and executable. Device memory
can't be executable, so this combination should never be used
and it is safe to use as a terminator value.
Therefore by changing the termination logic to use attributes
instead of size we prevent terminating the loop when we don't
intend to.
