fdcd54132b refactor(juno): update SDS driver calls
Update SDS driver calls to align with recent
changes [1] of the SDS driver.

- The driver now requires us to explicitly pass
  the SDS region id to act on.
- Implement plat_sds_get_regions() platform function
  which is used by the driver to get SDS region
  information per platform.

b65dfe40ae chore(auth)!: remove CryptoCell-712/713 support
CryptoCell-712 and CryptoCell-713 drivers have been deprecated since
TF-A v2.9 and their removal was announced for TF-A v2.10 release.
See [1].

As the release is approaching, this patch deletes these drivers' code as
well as all references to them in the documentation and Arm platforms
code (Nuvoton platform is taken care in a subsequent patch). Associated
build options (ARM_CRYPTOCELL_INTEG and PLAT_CRYPTOCELL_BASE) have also
been removed and thus will have no effect if defined.

This is a breaking change for downstream platforms which use these
drivers.

[1] https://trustedfirmware-a.readthedocs.io/en/v2.9/about/release-information.html#removal-of-deprecated-drivers
    Note that TF-A v3.0 release later got renumbered into v2.10.

986c4e991a feat(ethos-n): add separate RO and RW NSAIDs
To be able to further restrict the memory access for the Arm(R)
Ethos(TM)-N NPU, separate read-only and read/write NSAIDs for the

33bcaed121 feat(ethos-n)!: load NPU firmware at BL2
BL2 on Juno now loads the Arm(R) Ethos(TM)-N NPU firmware into a fixed
address, using the existing image loading framework.

Includes support for TRUSTED_BOARD_BOOT, if enabled, using the firmware
content and key certificates from the FIP.

Supports the ARM_IO_IN_DTB option so can specify the firmware location
from the dtb rather than it being hardcoded to the FIP

Update makefile to automatically embed the appropriate images into the
FIP.

BREAKING CHANGE: Building the FIP when TZMP1 support is enabled in the
NPU driver now requires a parameter to specify the NPU firmware file.

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.

5d5fb10f9c plat/arm/juno: Add support to use hw_config in BL31
To make it possible to use the hw_config device tree for dynamic
configuration in BL31 on the Arm Juno platform. A placeholder hw_config
has been added that is included in the FIP and a Juno specific BL31
setup has been added to populate fconf with the hw_config.

Juno's BL2 setup has been updated to align it with the new behavior
implemented in the Arm FVP platform, where fw_config is passed in arg1
to BL31 instead of soc_fw_config. The BL31 setup is expected to use the
fw_config passed in arg1 to find the hw_config.

e7b390892d ROMLIB: Optimize memory layout when ROMLIB is used
ROMLIB extract functions code from BL images to put them inside ROM.
This has for effect to reduce the size of the BL images.

This patch take this size reduction into consideration to optimize the

A new "PLAT_ARM_BL2_ROMLIB_OPTIMIZATION" macro is defined and used to
reduce "PLAT_ARM_MAX_BL2_SIZE". This allows to remove the gap between
BL1 and BL2 when ROMLIB is used and provides more room for BL31.

The current memory gain is 0x6000 for fvp and 0x8000 for juno.

402b3cf876 Switch AARCH32/AARCH64 to __aarch64__
NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__.

All common C compilers pre-define the same macros to signal which
architecture the code is being compiled for: __arm__ for AArch32 (or
earlier versions) and __aarch64__ for AArch64. There's no need for TF-A
to define its own custom macros for this. In order to unify code with
the export headers (which use __aarch64__ to avoid another dependency),
let's deprecate the AARCH32 and AARCH64 macros and switch the code base
over to the pre-defined standard macro. (Since it is somewhat
unintuitive that __arm__ only means AArch32, let's standardize on only
using __aarch64__.)

de8bc83ee9 n1sdp: add code for DDR ECC enablement and BL33 copy to DDR
N1SDP platform supports RDIMMs with ECC capability. To use the ECC
capability, the entire DDR memory space has to be zeroed out before
enabling the ECC bits in DMC620. Zeroing out several gigabytes of
memory from SCP is quite time consuming so functions are added that
zeros out the DDR memory from application processor which is
much faster compared to SCP. BL33 binary cannot be copied to DDR memory
before enabling ECC so this is also done by TF-A from IOFPGA-DDR3
memory to main DDR4 memory after ECC is enabled.

Original PLAT_PHY_ADDR_SPACE_SIZE was limited to 36-bits with which
the entire DDR space cannot be accessed as DRAM2 starts in base
0x8080000000. So these macros are redefined for all ARM platforms.

5b8d50e407 plat/arm: Save BL2 descriptors to reserved memory.
On ARM platforms, the BL2 memory can be overlaid by BL31/BL32. The memory
descriptors describing the list of executable images are created in BL2
R/W memory, which could be possibly corrupted later on by BL31/BL32 due
to overlay. This patch creates a reserved location in SRAM for these
descriptors and are copied over by BL2 before handing over to next BL
image.

Also this patch increases the PLAT_ARM_MAX_BL2_SIZE for juno when TBBR
is enabled.

09d40e0e08 Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

0f58d4f2c8 plat/arm: Remove file arm_board_def.h
This file is shared between FVP and all CSS platforms. While it may be
true that some definitions can be common, it doesn't make sense
conceptually. For example, the stack size depends on the platform and so
does the SRAM size.

After removing them, there are not enough common definitions to justify
having this header, so the other definitions have been moved to the
platform_def.h of FVP, board_css_def.h and arm_def.h.

FVP, SGI and SGM were using the definitions in board_arm_def.h. The
definitions have been copied to each platform's platform_def.h. Juno
was already using the ones in platform_def.h, so there have been no
changes.

d323af9e3d Rework page table setup for varying number of mem regions
Change arm_setup_page_tables() to take a variable number of memory
regions. Remove coherent memory region from BL1, BL2 and BL2U as
their coherent memory region doesn't contain anything and
therefore has a size of 0. Add check to ensure this
doesn't change without us knowing.

2013d8f05a Juno: Bump up the BL1-RW size
This patch bumps up the BL1-RW size for Juno and at the same time reduces
the BL2 size when TBB is enabled, TF_MBEDTLS_KEY_ALG=rsa+ecdsa. The BL2
size for this config is reduced as it was observed that the peak memory
usage is only reached when SPD=opteed and the dual rsa+ecdsa support is
not needed for this case.

c099cd3942 ARM platforms: Move BL31 below BL2 to enable BL2 overlay
The patch changes the layout of BL images in memory to enable
more efficient use of available space. Previously BL31 was loaded
with the expectation that BL2 memory would be reclaimed by BL32
loaded in SRAM. But with increasing memory requirements in the
firmware, we can no longer fit BL32 in SRAM anymore which means the
BL2 memory is not reclaimed by any runtime image. Positioning BL2
below BL1-RW and above BL31 means that the BL31 NOBITS can be
overlaid on BL2 and BL1-RW.

This patch also propogates the same memory layout to BL32 for AArch32
mode. The reset addresses for the following configurations are also
changed :
   * When RESET_TO_SP_MIN=1 for BL32 in AArch32 mode
   * When BL2_AT_EL3=1 for BL2

The restriction on BL31 to be only in DRAM when SPM is enabled
is now removed with this change. The update to the firmware design
guide for the BL memory layout is done in the following patch.

638b034cc3 ARM platforms: Demonstrate mem_protect from el3_runtime
Previously mem_protect used to be only supported from BL2. This is not
helpful in the case when ARM TF-A BL2 is not used. This patch demonstrates
mem_protect from el3_runtime firmware on ARM Platforms specifically
when RESET_TO_BL31 or RESET_TO_SP_MIN flag is set as BL2 may be absent
in these cases. The Non secure DRAM is dynamically mapped into EL3 mmap
tables temporarily and then the protected regions are then cleared. This
avoids the need to map the non secure DRAM permanently to BL31/sp_min.

The stack size is also increased, because DYNAMIC_XLAT_TABLES require
a bigger stack.

83a2376e18 Juno: Increase bl2 max size to fix build when SPD=opteed
Building TBBR(SPD=opteed) and non-TBBR TF-A images is breaking for
Juno for different configurations listed below:

* Overflow error of 4096 bytes for rsa algorithm.
* Overflow error of 8192 bytes for ecdsa algorithm.
* Overflow error of 4096 bytes for rsa+ecdsa algorithm.
* Overflow error of 4096 bytes for non-TBBR case.

So this patch increments macro PLAT_ARM_MAX_BL2_SIZE for all the above
cases accordingly.

cab0b5b045 ARM Platforms: Load HW_CONFIG in BL2
The patch adds the necessary changes to load HW_CONFIG in BL2 for
ARM Platforms :

1. The load address of HW_CONFIG is specified via the `hw_config_addr`
property in TB_FW_CONFIG is loaded by BL1. The `hw_config_max_size`
property defines the maximum size to be expected for the HW_CONFIG.
The `arm_dyn_cfg_helpers.c` and corresponding header implements
utility functions to parse these DT properties defined.
The `arm_dyn_cfg.c` implements wrappers to these helpers to enable
them to be invoked from ARM platform layer.

2. `HW_CONFIG` is added to the `bl2_mem_params_descs[]` array which is
the list of images to be loaded by BL2.

3. The `libfdt` sources are now included when BL2 is built

4. A new helper `populate_next_bl_params_config()` is introduced in
desc_image_load.c to populate the subsequent executable BL images
with the `hw_config` and the corresponding `fw_config` if available.
The `plat_get_next_bl_params()` API for ARM platforms is modified to
invoke this new helper.

5. The implementation of `bl2_early_platform_setup2()` is modified to
consider `arg0` as well in addition to `arg1` passed from BL1.

6. Bump up the BL2 size for Juno to accommodate the inclusion of libfdt.
