Top level sections are not numbered. Adding numbers makes referring to
sections easier. For example the Maintainers page changes from
"about/3.1" to simply "1.3.1".

docs(build): clarify getting started section
The Getting started section is very difficult to follow. Building the
fip comes before building the files it needs, the BL33 requirement is
given in a somewhat hand wavy way, and the Arm Developer website
download provides a lot of targets and the guide is not clear which ones
are needed on download.
Swapping the initial build and supporting tools sections makes the flow
more natural and the supporting tools section then becomes clear.
Explicitly mentioning the GCC targets avoids confusion for people less
familiar with the project (eg. new starters).

sphinx-build is passed a blanket "." to build all docs. However, if a

to build it which will fail due to some weird files it has.

fix(rockchip): align fdt buffer on 8 bytes
Since commit 94b2f94bd632 ("feat(libfdt): upgrade libfdt source files"),
8-byte alignment of the FDT address is enforced to follow the DT
standard.
Rockchip implementation of params_early_setup loads the FDT address as
passed by the bootloader into a buffer. This buffer is currently made of
uint8_t which means it is not 8-byte aligned and might result in
fdt_open_into failing.
Instead, let's make this buffer uint64_t to make it 8-byte aligned.

refactor(security): add OpenSSL 1.x compatibility
When updated to work with OpenSSL 3.0, the host tools lost their
compatibility with previous versions (1.x) of OpenSSL. This is
mainly due to the fact that 1.x APIs became deprecated in 3.0 and
therefore their use cause compiling errors. In addition, updating
for a newer version of OpenSSL meant improving the stability
against security threats. However, although version 1.1.1 is
now deprecated, it still receives security updates, so it would
not imply major security issues to keep compatibility with it too.
This patch adds backwards compatibility with OpenSSL 1.x versions
by adding back 1.x API code. It defines a macro USING_OPENSSL3,
which will select the appropriate OpenSSL API version depending on
the OpenSSL library path chosen (which is determined by the
already-existing OPENSSL_DIR variable).
In addition, cleanup items were packed in functions and moved to
the proper modules in order to make the code more maintainable and
legible.

feat(cpus): make cache ops conditional
When a core is in debug recovery mode its caches are not invalidated
upon reset, so the L1 and L2 cache contents from before reset are
observable after reset. Similarly, debug recovery mode of DynamIQ
cluster ensures that contents of the shared L3 cache are also not
invalidated upon transition to On mode.
Booting cores in debug recovery mode means booting with caches disabled
and preserving the caches until a point where software can dump the
caches and retrieve their contents. TF-A however unconditionally cleans
and invalidates caches at multiple points during boot. This can lead to
memory corruption as well as loss of cache contents to be used for
debugging.
This patch fixes this by calling a platform hook before performing CMOs
in helper routines in cache_helpers.S. The platform hook plat_can_cmo is
an assembly routine which must not clobber x2 and x3, and avoid using
stack. The whole checking is conditional upon `CONDITIONAL_CMO` which
can be set at compile time.
instead of it being lost in the middle of supported platform ports.

compatibility policy. The combined document gets renamed into a
