Limit support for region overlaps in xlat_tables
The only case in which regions can now overlap is if they are
identity mapped or they have the same virtual to physical address
offset (identity mapping is just a particular case of the latter).
They must overlap completely (i.e. one of them must be completely
inside the other one) and not cover the same area.
This allow future enhancements to the xlat_tables library without
having to support unnecessarily complex edge cases.
Outer regions are now sorted by mmap_add_region() before inner
regions with the same base virtual address for consistency: all
regions contained inside another one must be placed after the outer
one in the list.
If an inner region has the same attributes as the outer ones it will
be merged when creating the tables with init_xlation_table(). This
cannot be done as regions are added because there may be cases where
adding a region makes previously mergeable regions no longer
mergeable.
If the attributes of an inner region are different than the outer
region, new pages will be generated regardless of how "restrictive"
they are. For example, RO memory is more restrictive than RW. The
old implementation would give priority to RO if there is an overlap,
the new one doesn't.
NOTE: THIS IS THEORETICALLY A COMPATABILITY BREAK FOR PLATFORMS THAT
USE THE XLAT_TABLES LIBRARY IN AN UNEXPECTED WAY. PLEASE RAISE A
TF-ISSUE IF YOUR PLATFORM IS AFFECTED.

Fix build error with optimizations disabled (-O0)
If Trusted Firmware is built with optimizations disabled (-O0), the
linker throws the following error:
undefined reference to 'xxx'
Where 'xxx' is a raw inline function defined in a header file. The
reason is that, with optimizations disabled, GCC may decide to skip
the inlining. If that is the case, an external definition to the
compilation unit must be provided. Because no external definition
is present, the linker throws the error.
This patch fixes the problem by declaring the following inline
functions static, so the internal definition is used:
- cm_set_next_context()
- bakery_lock_init()
Note that building the TF with optimizations disabled when Trusted
Board Boot is enabled is currently unsupported, as this makes the BL2
image too big to fit in memory without any adjustment of its base
address. Similarly, disabling optimizations for debug builds on FVP
is unsupported at the moment.

Give user's compiler flags precedence over default ones
The user can provide additional CFLAGS to use when building TF.
However, these custom CFLAGS are currently prepended to the
standard CFLAGS that are hardcoded in the TF build system. This
is an issue because when providing conflicting compiler flags
(e.g. different optimisations levels like -O1 and -O0), the last
one on the command line usually takes precedence. This means that
the user flags get overriden.
To address this problem, this patch separates the TF CFLAGS from
the user CFLAGS. The former are now stored in the TF_CFLAGS make
variable, whereas the CFLAGS make variable is untouched and reserved
for the user. The order of the 2 sets of flags is enforced when
invoking the compiler.

Make:Improve version string generation portability
To get round problems encountered when building in a DOS build
environment the generation of the .o file containing build identifier
strings is modified.
The problems encounterred were:
1. DOS echo doesn't strip ' characters from the output text.
2. git is not available from CMD.EXE so the BUILD_STRING value needs
some other origin.
A BUILD_STRING value of "development build" is used for now.
MAKE_BUILD_STRINGS is used to customise build string generation in a DOS
environment. This variable is not defined in the UNIX build environment
make file helper, and so the existing build string generation behaviour
is retained in these build environments.
NOTE: This commit completes a cumulative series aimed at improving
build portability across development environments.
This enables the build to run on several new build environments,
if the relevant tools are available.
At this point the build is tested on Windows 7 Enterprise SP1,
using CMD.EXE, Cygwin and Msys (MinGW),as well as a native
Linux envionment". The Windows platform builds used
aarch64-none-elf-gcc.exe 4.9.1. CMD.EXE and Msys used Gnu
Make 3.81, cygwin used Gnu Make 4.1.

Initialize secondary CPUs during cold boot
The previous reset code in BL1 performed the following steps in
order:
1. Warm/Cold boot detection.
If it's a warm boot, jump to warm boot entrypoint.
2. Primary/Secondary CPU detection.
If it's a secondary CPU, jump to plat_secondary_cold_boot_setup(),
which doesn't return.
3. CPU initialisations (cache, TLB...).
4. Memory and C runtime initialization.
For a secondary CPU, steps 3 and 4 are never reached. This shouldn't

The main concern is the lack of secondary CPU initialization when

initialisation themselves.

Extend memory attributes to map non-cacheable memory
At the moment, the memory translation library allows to create memory
mappings of 2 types:
- Device nGnRE memory (named MT_DEVICE in the library);
- Normal, Inner Write-back non-transient, Outer Write-back
non-transient memory (named MT_MEMORY in the library).
As a consequence, the library code treats the memory type field as a
boolean: everything that is not device memory is normal memory and
vice-versa.
In reality, the ARMv8 architecture allows up to 8 types of memory to
be used at a single time for a given exception level. This patch
reworks the memory attributes such that the memory type is now defined
as an integer ranging from 0 to 7 instead of a boolean. This makes it
possible to extend the list of memory types supported by the memory
translation library.
The priority system dictating memory attributes for overlapping
memory regions has been extended to cope with these changes but the
algorithm at its core has been preserved. When a memory region is
re-mapped with different memory attributes, the memory translation
library examines the former attributes and updates them only if
the new attributes create a more restrictive mapping. This behaviour
is unchanged, only the manipulation of the value has been modified
to cope with the new format.
This patch also introduces a new type of memory mapping in the memory
translation library: MT_NON_CACHEABLE, meaning Normal, Inner
Non-cacheable, Outer Non-cacheable memory. This can be useful to map
a non-cacheable memory region, such as a DMA buffer for example.
The rules around the Execute-Never (XN) bit in a translation table
for an MT_NON_CACHEABLE memory mapping have been aligned on the rules
used for MT_MEMORY mappings:
- If the memory is read-only then it is also executable (XN = 0);
- If the memory is read-write then it is not executable (XN = 1).
The shareability field for MT_NON_CACHEABLE mappings is always set as
'Outer-Shareable'. Note that this is not strictly needed since
shareability is only relevant if the memory is a Normal Cacheable
memory type, but this is to align with the existing device memory
mappings setup. All Device and Normal Non-cacheable memory regions
are always treated as Outer Shareable, regardless of the translation
table shareability attributes.
This patch also removes the 'ATTR_SO' and 'ATTR_SO_INDEX' #defines.
They were introduced to map memory as Device nGnRnE (formerly called
"Strongly-Ordered" memory in the ARMv7 architecture) but were not
used anywhere in the code base. Removing them avoids any confusion
about the memory types supported by the library.
Upstream platforms do not currently use the MT_NON_CACHEABLE memory
type.
NOTE: THIS CHANGE IS SOURCE COMPATIBLE BUT PLATFORMS THAT RELY ON THE
BINARY VALUES OF `mmap_attr_t` or the `attr` argument of
`mmap_add_region()` MAY BE BROKEN.
