Jens Wiklander f58237ccd9 feat(plat/qemu): add SPMD support with SPMC at S-EL1
Adds support for SPMD with SPMC at S-EL1. A new config option SPMC_OPTEE
is added to support loading the special OP-TEE images when configured
with SPD=spmd. With or without SPMC_OPTEE. It should still be possible
to load another BL32 payload implementing a SPMC, provided that entry
point is the same as load address, that is, BL32_BASE.

Chris Kay 1fa05dab07 build(fdt-wrappers): introduce FDT wrappers makefile
This has been introduced to simplify dependencies on the FDT wrappers.
We generally want to avoid pulling in components on a file-by-file
basis, particularly as we are trying to draw conceptual boxes around
components in preparation for transitioning the build system to CMake,
where dependencies are modelled on libraries rather than files.

We ignore the error information return by console_flush in _every_

work around the MISRA violation that this causes. Instead, we collect
the error information from the driver (to avoid changing that API), and
don't return it to the caller.

Issue seems to be occurred when 'ROT key' is generated before creating
the platform build folder(for e.g.build/qemu/debug).

Changes are made to fix this issue by adding orderly dependancy of
the platform folder for the 'ROT key' creation which ensures that
platform folder is created before generating 'ROT key'.

Radoslaw Biernacki fa405e3b82 qemu/qemu_sbsa: Adding memory mapping for both FLASH0/FLASH1
This patch adds mapping for secure FLASH0 for qemu/virt and
qemu/qemu_sbsa platforms. This change is targeted for sbsa but since both
platforms share common code, changes in common defines was necessary.

For qemu_sbsa, this patch adds necessary mapping in order to boot without
semi-hosting from secure FLASH0. EFI need to stay in FLASH1 (share it with
variables) since it need to "run in place" in non secure domain. Changes
for this are under RFC at edk2-platforms mailing list:
https://patches.linaro.org/patch/171327/
(edk2-platforms/Platform/Qemu/SbsaQemu/SbsaQemu.dsc).

In docs qemu/virt is described as using semi-hosting, therefore this change
should be orthogonal to existing assumptions while giving possibility to
store both bl1 and fip in FLASH0 at some point (additional changes required
for that).

Radoslaw Biernacki 9a006ad105 qemu: Simplify the image size calculation
Patch introduce the macro NS_IMAGE_MAX_SIZE to simplify the image size
calculation. Use of additional parenthesis removes the possibility of
improper calculations due nested macro expansion for subtraction.
In case of platforms with DRAM window over 32bits, patch also removes
potential problems with type casting, as meminfo.image_size is uint32_t
but macro calculations were done in 64bit space.

Radoslaw Biernacki 301d27d998 qemu: introducing sub-platforms to qemu platform
This commit change the plat/qemu directory structure into:

`-- plat
    `-- qemu
        |-- common    (files shared with all qemu subplatforms)
        |-- qemu      (original qemu platform)
        |-- qemu_sbsa (new sqemu_sbsa platform)
        |-- subplat1
        `-- subplat2

This opens the possibility of adding new qemu sub-platforms which reuse
existing common platform code. The first platform which will leverage new
structure will be SBSA platform.

Andre Przywara f240728b76 qemu: Move and generalise FDT PSCI fixup
The QEMU platform port scans its device tree to advertise PSCI as the
CPU enable method. It does this by scanning *every* node in the DT and
check whether its compatible string starts with "arm,cortex-a". Then it
sets the enable-method to PSCI, if it doesn't already have one.

Other platforms might want to use this functionality as well, so let's
move it out of the QEMU platform directory and make it more robust by
fixing some shortcomings:
- A compatible string starting with a certain prefix is not a good way
to find the CPU nodes. For instance a "arm,cortex-a72-pmu" node will
match as well and is in turn favoured with an enable-method.
- If the DT already has an enable-method, we won't change this to PSCI.

Those two issues will for instance fail on the Raspberry Pi 4 DT.
To fix those problems, we adjust the scanning method:
The DT spec says that all CPU nodes are subnodes of the mandatory
/cpus node, which is a subnode of the root node. Also each CPU node has
to have a device_type = "cpu" property. So we find the /cpus node, then
scan for a subnode with the proper device_type, forcing the
enable-method to "psci".
We have to restart this search after a property has been patched, as the
node offsets might have changed meanwhile.

This allows this routine to be reused for the Raspberry Pi 4 later.

Julius Werner 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__.)

Hongbo Zhang d27c880a36 plat/qemu: add gicv3 support for qemu
This patch adds gicv3 support for qemu, in order not to break any legacy
use case, gicv2 is still set by default, gicv3 can be selected by
compiling parameter QEMU_USE_GIC_DRIVER=QEMU_GICV3.
