feat: add support for poetry
New python dependencies are introduced by the memory mapping script.
Rather than add another `requirements.txt` utilise poetry. This is a
proper dependency management framework for Python. The two main upsides
of using poetry instead of the traditional requirements.txt are
maintainability and reproducibility.
Poetry provides a proper lock file for pinning dependencies, similar to
npm for JavaScript. This allows for separate environments (i.e. docs,
tools) to be created efficiently, and in a reproducible manner, wherever
the project is deployed. Having dependencies pinned in this manner is a
boon as a security focused project. An additional upside is that we will
receive security updates for dependencies via GitHub's Dependabot.

This change allows warm reboots of UEFI on Raspberry Pi 3B+ where

The basic idea is that some initial configuration parameters

that matters is the "slow card" bit, but the initial clock setting
also seemed wrong to me.

docs(porting): refer the reader back to the threat model
When porting TF-A to a new platform, it is essential to read the
threat model documents in conjunction with the porting guide to
understand the security responsibilities of each platform interface
to implement.
Add a note to highlight this in the porting guide.
docs(porting): move porting guide upper in table of contents
The porting guide is currently hosted under the 'Getting started'
section. Yet, porting the full firmware to a new platform is probably
not the first thing that one would do. Before delving into the
details, one would probably start by building the code for an emulated
platform, such as Arm FVP.
Furthermore, the porting guide is such a big and important document
that it probably deserves being visible in the main table of contents.
Thus, move it just above the list of supported platforms.
fix(intel): update boot scratch to indicate to Uboot is PSCI ON
There is a use case where kernel requested ATF to power off/on only CPU0.
However, after ATF power off/on CPU0, CPU0 did not back into the state
to wait for ATF. Instead, CPU0 continue to reentry SPL boot sequence
because CPU0 is master/primary core. This causing the system reboot from
SPL again, while the slave core still in kernel.
To resolve this, ATF is set the boot scratch register 8 bit 17 whenever
it is a request from kernel to power off/on only CPU0. So, if this boot
scratch bit is set, CPU 0 will be able to put into a state to wait for
ATF.
Qemu-tcg with GICv3 emulation enabled will by default configure MPIDR
topology to report up to 16 cpus per cluster. This is NOT overriden by
qemu's -smp setting, e.g. -smp 8,clusters=2,cores=4,threads=1 will still
generate MPIDR reads as if all 8 CPUs were within one cluster.
Increase the hardcoded limit to reflect that so that we accept PSCI
calls that provide MPIDRs based on what was actually read from the
emulated CPU.

This comes arguably from us somewhat abusing pointers to access MMIO

Replace the pointer-dereferencing mmio_read_8() with an implementation
that uses inline assembly, to directly generate an 8-bit load
instruction. This avoids the compiler thinking that this access is using
a pointer it needs to jealously look after.

encodes the maximum size of the arguments, not necessarily whether they
are used from AArch64 or AArch32. So while some functions exist in both
worlds (CPU_ON, for instance), some functions take no or only 32-bit

fix(fconf): fix FCONF_ARM_IO_UUID_NUMBER value
The FCONF_ARM_IO_UUID_NUMBER macro is hardcoded to the number of entries
in the `load_info` array, but this number did not match the actual
length of the array in the case that TRUSTED_BOARD_BOOT is defined, but
SPD_spmd is not defined.
This patch fixes the hardcoded length by replacing it with a more
flexible calculation which sums up the various contributing groups of
entries.

To workaround Arm(R) Ethos(TM)-N NPU erratum 2838783, the NPU has been
configured to allow being woken up by both secure and non-secure events
to make sure that an event always wakes up the NPU.
The API version has been given a minor version bump with this change to
indicate that this fix is included.

For the TZC to allow the Arm(R) Ethos(TM)-N NPU to access the buffers
allocated in a protected memory region, it must include the correct
NSAID for that region in its transactions to the memory. This change
updates the SiP service to configure the NSAIDs specified by a platform
define. When doing a protected access the SiP service now configures the
NSAIDs specified by the platform define. For unprotected access the
NSAID is set to zero.

build(fiptool): add object dependency generation
The object target in the fiptool Makefile only depends on the
corresponding source file so it won't rebuild the object, if a header
file used by the source file is changed.
To make it rebuild the object file for both source and header file
changes, a dependency file will now be generated for each object and
included in the Makefile.

TZMP1 protected memory regions have been added in the Juno platform to
store sensitive data for the Arm(R) Ethos(TM)-N NPU
This is enabled when building TF-A with ARM_ETHOSN_NPU_TZMP1.
The NPU uses two protected memory regions:
1) Firmware region to protect the NPU's firmware from being modified
from the non-secure world
2) Data region for sensitive data used by the NPU
Respective memory region can only be accessed with their unique NSAID.

This is controlled in build time by the now added build flag.
The new build flag is only supported with the Arm Juno platform and the
TZC is configured with default memory regions as if TZMP1 wasn't
enabled to facilitate adding the new memory regions later.
