Alexei Fedorov b3c431f35b FVP: Fix incorrect GIC mapping
This patch fixes incorrect setting for DEVICE1_SIZE
for FVP platforms with more than 8 PEs.
The current value of 0x200000 supports only 8 PEs
and causes exception for FVP platforms with the greater
number of PEs, e.g. FVP_Base_Cortex_A65AEx8 with 16 PEs
in one cluster.

Petre-Ionut Tudor 60e8f3cfd5 Read-only xlat tables for BL31 memory
This patch introduces a build flag which allows the xlat tables
to be mapped in a read-only region within BL31 memory. It makes it
much harder for someone who has acquired the ability to write to
arbitrary secure memory addresses to gain control of the
translation tables.

The memory attributes of the descriptors describing the tables
themselves are changed to read-only secure data. This change
happens at the end of BL31 runtime setup. Until this point, the
tables have read-write permissions. This gives a window of
opportunity for changes to be made to the tables with the MMU on
(e.g. reclaiming init code). No changes can be made to the tables
with the MMU turned on from this point onwards. This change is also
enabled for sp_min and tspd.

To make all this possible, the base table was moved to .rodata. The
penalty we pay is that now .rodata must be aligned to the size of
the base table (512B alignment). Still, this is better than putting
the base table with the higher level tables in the xlat_table
section, as that would cost us a full 4KB page.

Changing the tables from read-write to read-only cannot be done with
the MMU on, as the break-before-make sequence would invalidate the
descriptor which resolves the level 3 page table where that very
descriptor is located. This would make the translation required for
writing the changes impossible, generating an MMU fault.

The caches are also flushed.

Alexei Fedorov 6227cca9e8 FVP: Fix BL31 load address and image size for RESET_TO_BL31=1
When TF-A is built with RESET_TO_BL31=1 option, BL31 is the
first image to be run and should have all the memory allocated
to it except for the memory reserved for Shared RAM at the start
of Trusted SRAM.
This patch fixes FVP BL31 load address and its image size for
RESET_TO_BL31=1 option. BL31 startup address should be set to
0x400_1000 and its maximum image size to the size of Trusted SRAM
minus the first 4KB of shared memory.
Loading BL31 at 0x0402_0000 as it is currently stated in
'\docs\plat\arm\fvp\index.rst' causes EL3 exception when the
image size gets increased (i.e. building with LOG_LEVEL=50)
but doesn't exceed 0x3B000 not causing build error.

Khandelwal c6fe43b726 Corstone700: add support for mhuv2 in arm TF-A
Note: This patch implements in-band messaging protocol only.
ARM has launched a next version of MHU i.e. MHUv2 with its latest
subsystems. The main change is that the MHUv2 is now a distributed IP
with different peripheral views (registers) for the sender and receiver.

Another main difference is that MHUv1 duplex channels are now split into
simplex/half duplex in MHUv2. MHUv2 has a configurable number of
communication channels. There is a capability register (MSG_NO_CAP) to
find out how many channels are available in a system.

The register offsets have also changed for STAT, SET & CLEAR registers
from 0x0, 0x8 & 0x10 in MHUv1 to 0x0, 0xC & 0x8 in MHUv2 respectively.

0x0    0x4  0x8  0xC             0x1F
------------------------....-----
| STAT |    |    | SET |    |   |
------------------------....-----
      Transmit Channel

0x0    0x4  0x8   0xC            0x1F
------------------------....-----
| STAT |    | CLR |    |    |   |
------------------------....-----
        Receive Channel

The MHU controller can request the receiver to wake-up and once the
request is removed, the receiver may go back to sleep, but the MHU
itself does not actively put a receiver to sleep.

So, in order to wake-up the receiver when the sender wants to send data,
the sender has to set ACCESS_REQUEST register first in order to wake-up
receiver, state of which can be detected using ACCESS_READY register.
ACCESS_REQUEST has an offset of 0xF88 & ACCESS_READY has an offset
of 0xF8C and are accessible only on any sender channel.

This patch adds necessary changes in a new file required to support the
latest MHUv2 controller. This patch also needs an update in DT binding
for ARM MHUv2 as we need a second register base (tx base) which would
be used as the send channel base.

Vijayenthiran Subramaniam 2d4b719cc6 board/rdn1edge: add support for dual-chip configuration
RD-N1-Edge based platforms can operate in dual-chip configuration
wherein two rdn1edge SoCs are connected through a high speed coherent
CCIX link.

This patch adds a function to check if the RD-N1-Edge platform is
operating in multi-chip mode by reading the SID register's NODE_ID
value. If operating in multi-chip mode, initialize GIC-600 multi-chip
operation by overriding the default GICR frames with array of GICR
frames and setting the chip 0 as routing table owner.

The address space of the second RD-N1-Edge chip (chip 1) starts from the
address 4TB. So increase the physical and virtual address space size to
43 bits to accommodate the multi-chip configuration. If the multi-chip
mode configuration is detected, dynamically add mmap entry for the
peripherals memory region of the second RD-N1-Edge SoC. This is required
to let the BL31 platform setup stage to configure the devices in the
second chip.

PLATFORM_CORE_COUNT macro is set to be multiple of CSS_SGI_CHIP_COUNT
and topology changes are added to represent the dual-chip configuration.

In order the build the dual-chip platform, CSS_SGI_CHIP_COUNT macro
should be set to 2:
export CROSS_COMPILE=<path-to-cross-compiler>
make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

two processing elements (PE) per CPU. Commit a9fbf13e04 (plat/arm/sgi:
move topology information to board folder) defined the RD-E1-Edge
topology tree to have two clusters with eight CPUs each but PE per CPU
entries were not added. This patch fixes the topology tree accordingly.

Vijayenthiran Subramaniam 4d37aa76fd plat/arm/sgi: introduce number of chips macro
Introduce macro 'CSS_SGI_CHIP_COUNT' to allow Arm CSS platforms with
multi-chip support to define number of chiplets on the platform. By
default, this flag is set to 1 and does not affect the existing single
chip platforms.

For multi-chip platforms, override the default value of
CSS_SGI_CHIP_COUNT with the number of chiplets supported on the
platform. As an example, the command below sets the number of chiplets
to two on the RD-N1-Edge multi-chip platform:

export CROSS_COMPILE=<path-to-cross-compiler>
make PLAT=rdn1edge CSS_SGI_CHIP_COUNT=2 ARCH=aarch64 all

Louis Mayencourt 9739982125 arm-io: Panic in case of io setup failure
Currently, an IO setup failure will be ignored on arm platform release
build. Change this to panic instead.

Louis Mayencourt d6dcbcad18 MISRA fix: Use boolean essential type
Change the return type of "arm_io_is_toc_valid()" and
"plat_arm_bl1_fwu_needed()" to bool, to match function behavior.

Louis Mayencourt 0a6e7e3b76 fconf: Move platform io policies into fconf
Use the firmware configuration framework to store the io_policies
information inside the configuration device tree instead of the static
structure in the code base.

The io_policies required by BL1 can't be inside the dtb, as this one is
loaded by BL1, and only available at BL2.

This change currently only applies to FVP platform.

Louis Mayencourt 25ac87940c fconf: Add dynamic config DTBs info as property
This patch introduces a better separation between the trusted-boot
related properties, and the dynamic configuration DTBs loading
information.

The dynamic configuration DTBs properties are moved to a new node:
`dtb-registry`. All the sub-nodes present will be provided to the
dynamic config framework to be loaded. The node currently only contains
the already defined configuration DTBs, but can be extended for future
features if necessary.
The dynamic config framework is modified to use the abstraction provided
by the fconf framework, instead of directly accessing the DTBs.

The trusted-boot properties are kept under the "arm,tb_fw" compatible
string, but in a separate `tb_fw-config` node.
The `tb_fw-config` property of the `dtb-registry` node simply points
to the load address of `fw_config`, as the `tb_fw-config` is currently
part of the same DTB.

Louis Mayencourt 3b5ea741fd fconf: Load config dtb from bl1
Move the loading of the dtb from arm_dym_cfg to fconf. The new loading
function is not associated to arm platform anymore, and can be moved
to bl_main if wanted.
