Overview
---------

BOOTROM starts the cpu at EL3; In this port BL2 will therefore be entered
at this exception level (the Renesas' ATF reference tree [1] resets into
EL1 before entering BL2 - see its bl2.ld.S)

BL2 initializes DDR (and i2c to talk to the PMIC on some platforms)
before determining the boot reason (cold or warm).

During suspend all CPUs are switched off and the DDR is put in
backup mode (some kind of self-refresh mode). This means that BL2 is
always entered in a cold boot scenario.

Once BL2 boots, it determines the boot reason, writes it to shared
memory (BOOT_KIND_BASE) together with the BL31 parameters
(PARAMS_BASE) and jumps to BL31.

To all effects, BL31 is as if it is being entered in reset mode since
it still needs to initialize the rest of the cores; this is the reason
behind using direct shared memory access to  BOOT_KIND_BASE and
PARAMS_BASE instead of using registers to get to those locations (see
el3_common_macros.S and bl31_entrypoint.S for the RESET_TO_BL31 use
case).

Depending on the boot reason BL31 initializes the rest of the cores:
in case of suspend, it uses a MBOX memory region to recover the
program counters.

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

restores the logic the i.MX controller requires without breaking it for
everyone else.

This is the case for SGI_MAP_FLASH0_RO, defined in the file

This problem is solved by checking both size and attributes in xlat v1.

Makefile: Support totally quiet output with -s

"-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:
==========

tools: Make invocation of host compiler correct

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.

following error message is printed:

 Makefile:291: *** recipe commences before first target.  Stop.

tools: Fix broken object compilation rules

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.

marvell: Move BLE from external repo to the platform folder

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.

FVP: Reclaim init code for the stack

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.
