Instead of stringizing the paths to binary files, add them as string
defines on the command line (e.g. -DFOO=\"BAR\" instead of -DFOO=BAR).
This prevents macros from being expanded inside the string value itself.
For example, -DFOO=/path/with-linux-in-it would have been expanded to
"/path/with-1-in-it" because `linux=1` is one of the standard GCC
defines.

When a Firmware is complied as Position Independent Executable it needs
to request GDT fixup by passing size of the memory region to
el3_entrypoint_common macro.
The Global descriptor table fixup will be done early on during cold boot
process of primary core.
Currently only BL31 supports PIE, but in future when BL2_AT_EL3 will be
compiled as PIE, it can simply pass fixup size to the common el3
entrypoint macro to fixup GDT.
The reason for this patch was to overcome the bug introduced by SHA
330ead806 which called fixup routine for each core causing
re-initializing of global pointers thus overwriting any changes
done by the previous core.

Currently tb_fw_cfg_dtb size is fixed to max, which is generally a page

with the libfdt "fdt_totalsize" function.
This avoid flushing extra memory after updating the dtb with mbedtls
heap information when shared heap is used.

Currently, sections within .text/.rodata/.data/.bss are emitted in the
order they are seen by the linker. This leads to wasted space, when a
section with a larger alignment follows one with a smaller alignment.
We can avoid this wasted space by sorting the sections.
To take full advantage of this, we must disable generation of common
symbols, so "common" data can be sorted along with the rest of .bss.
An example of the improvement, from `make DEBUG=1 PLAT=sun50i_a64 bl31`:
.text => no change
.rodata => 16 bytes saved
.data => 11 bytes saved
.bss => 576 bytes saved
As a side effect, the addition of `-fno-common` in TF_CFLAGS makes it
easier to spot bugs in header files.

The current range check for the offset is wrong: it is counting bytes,
while indexing an array of uint32_t. Since the offset is always zero,
the parameter is unnecessary. Instead of adding more code to fix the
check, remove the parameter to avoid the problem entirely.

-Wunused-const-variable=1 is already included by -Wunused-variable,
which is part of -Wall. -Wunused-const-variable=2, which is what we have
been using as part of W=1, warns for unused static const variables in
headers, which will likely produce a lot of false positives that will
take a large effort to fix.
Additionally, some of these issues may be caused by different builds of
TF-A where some features are used in some builds and ignored in others.

This patch enables LTO for TF-A when compiled with GCC.
LTO is disabled by default and is enabled by
ENABLE_LTO=1 build option.
LTO is enabled only for aarch64 as there seem to be
a bug in the aarch32 compiler when LTO is enabled.
The changes in the makefiles include:
- Adding -flto and associated flags to enable LTO.
- Using gcc as a wrapper at link time instead of ld.
This is recommended when using LTO as gcc internally
takes care of invoking the necessary plugins for LTO.
- Adding switches to pass options to ld.
- Adding a flag to disable fix for erratum cortex-a53-843419
unless explicitly enabled. This is needed because GCC
seem to automatically add the erratum fix when used
as a wrapper for LD.
Additionally, this patch updates the TF-A user guide with
the new build option.

This patch introduces the 'plat_enable_console' handler to allow
the platform to enable the right console. Tegra194 platform supports
multiple console, while all the previous platforms support only one
console.
For Tegra194 platforms, the previous bootloader checks the platform
config and sets the uart-id boot parameter, to 0xFE. On seeing this
boot parameter, the platform port uses the proper memory aperture
base address to communicate with the SPE. This functionality is
currently protected by a platform macro, ENABLE_CONSOLE_SPE.
