Ming Huang 9feb1e2f4b plat/arm/css/sgi: Fix bl32 receive event - 0xC4000061 issue
The issue is that, when interrupt is triggered and RAS handler
is entered, after interrupt handler finishes, TF-A will re-enter
bl32 and then crash.
sdei_dispatch_event() may return failing result in some cases,
for example kernel may not have registered a handler or RAS event
may happen early during boot. We restore the NS context when
sdei_dispatch_event() returns failing result.

Jagadeesh Ujja 4d8c181963 plat/arm: css: Turn ON/OFF redistributor in sync with GIC CPU interface ON/OFF
Turn ON/OFF GIC redistributor in sync with GIC CPU interface ON/OFF.

Issue :
The Linux prompt hangs when all the cores in a cluster are turned OFF
and we try to turn ON a core in that cluster. Previously when TF-A turns
ON a core, TF-A first turns ON the redistributor followed by the core.
This did not match the flow when turning OFF a core, as TF-A did not
turn OFF redistributor when the corresponding core[s] are disabled.
This hang is resolved by disabling redistributor as cores are disabled,
keeping them in sync.

Pali Rohár a98122064d Makefile: Do not mark file targets as .PHONY target
Only non-file targets should be set a .PHONY. Otherwise if file target is
set as .PHONY then targets which depends on those file .PHONY targets would
be always rebuilt even when their prerequisites are not changed.

File target which needs to be always rebuilt can be specified in Make
system via having a prerequisite on some .PHONY target, instead of marking
whole target as .PHONY. In Makefile projects it is common to create empty
.PHONY target named FORCE for this purpose.

This patch changes all file targets which are set as .PHONY to depends on
new .PHONY target FORCE, to ensure that these file targets are always
rebuilt (as before). Basically they are those targets which calls external
make subprocess.

After FORCE target is specified in main Makefile, remove it from other
Makefile files to prevent duplicate definitions.

Alexei Fedorov 8109d2dd69 Merge "Use constant stack size with RECLAIM_INIT_CODE" into integration 2020-10-29 18:00:13 +00:00
David Horstmann 3ed5606bd1 Use constant stack size with RECLAIM_INIT_CODE
Currently, when RECLAIM_INIT_CODE is set, the
stacks are scaled to ensure that the entirety
of the init section can be reclaimed as stack.

This causes an issue in lib/psci/aarch64/psci_helpers.S,
where the stack size is used for cache operations in
psci_do_pwrdown_cache_maintenance(). If the stacks
are scaled, then the PSCI code may fail to invalidate
some of the stack memory before power down.

Resizing stacks is also not good for stability in general,
since code that works with a small number of cores may
overflow the stack when the number of cores is increased.

Change to make every stack be PLATFORM_STACK_SIZE big,
and allow the total stack to be smaller than the
init section.

Any pages of the init section not reclaimed as
stack will be set to read-only and execute-never,
for security.

Joanna Farley 943aff0c16 Merge "Increase type widths to satisfy width requirements" into integration 2020-10-18 14:51:00 +00:00
Jimmy Brisson d7b5f40823 Increase type widths to satisfy width requirements
Usually, C has no problem up-converting types to larger bit sizes. MISRA
rule 10.7 requires that you not do this, or be very explicit about this.
This resolves the following required rule:

    bl1/aarch64/bl1_context_mgmt.c:81:[MISRA C-2012 Rule 10.7 (required)]<None>
    The width of the composite expression "0U | ((mode & 3U) << 2U) | 1U |
    0x3c0U" (32 bits) is less that the right hand operand
    "18446744073709547519ULL" (64 bits).

This also resolves MISRA defects such as:

    bl2/aarch64/bl2arch_setup.c:18:[MISRA C-2012 Rule 12.2 (required)]
    In the expression "3U << 20", shifting more than 7 bits, the number
    of bits in the essential type of the left expression, "3U", is
    not allowed.

Further, MISRA requires that all shifts don't overflow. The definition of
PAGE_SIZE was (1U << 12), and 1U is 8 bits. This caused about 50 issues.
This fixes the violation by changing the definition to 1UL << 12. Since
this uses 32bits, it should not create any issues for aarch32.

This patch also contains a fix for a build failure in the sun50i_a64
platform. Specifically, these misra fixes removed a single and
instruction,

    92407e73        and     x19, x19, #0xffffffff

from the cm_setup_context function caused a relocation in
psci_cpus_on_start to require a linker-generated stub. This increased the
size of the .text section and caused an alignment later on to go over a
page boundary and round up to the end of RAM before placing the .data
section. This sectionn is of non-zero size and therefore causes a link
error.

The fix included in this reorders the functions during link time
without changing their ording with respect to alignment.

Andre Przywara 01301b116e arm_fpga: Add post-build linker script
For the Arm Ltd. FPGAs to run, we need to load several payloads into the
FPGA's memory:
- Some trampoline code at address 0x0, to jump to BL31's entry point.
- The actual BL31 binary at the beginning of DRAM.
- The (generic) DTB image to describe the hardware.
- The actual non-secure payloads (kernel, ramdisks, ...)

The latter is application specific, but the first three blobs are rather
generic.
Since the uploader tool supports ELF binaries, it seems helpful to
combine these three images into one .axf file, as this also simplifies
the command line.

Add a post-build linker script, that combines those three bits into one
ELF file, together with their specific load addresses.
Include a call to "ld" with this linker script in the platform Makefile,
so it will be build automatically. The result will be called "bl31.axf".

Andre Przywara f45c6d8623 arm_fpga: Add ROM trampoline
The application cores of the FPGAs used in Arm Ltd. start execution at
address 0x0. This is the location of some (emulated) ROM area (which can
be written to by the uploading tool).
Since the arm_fpga port is configured to run from DRAM, we load BL31 to
the beginning of DRAM (mapped at 2GB). This requires some small
trampoline code in the "ROM" to jump to the BL31 entry point.

To avoid some extra magic binary, add a tiny assembly file with that
trivial jump instruction to the tree, so this binary can be created
alongside BL31.

Andre Przywara b48883c79a arm_fpga: Add devicetree file
The FPGA images used in Arm Ltd. focus on CPU cores, so they share a
common platform, with a minimal set of peripherals (interconnect, GIC,
UART).
This allows to support most platforms with a single devicetree file.
The topology and number of CPU cores differ, but those will added at
runtime, in BL31. Other adjustments (GICR size, SPE node, command line)
are also done at this point.

Add the common devicetree file to TF-A's build system, so it can be
build together with BL31. At runtime, the resulting .dtb file should be
uploaded to the address given with FPGA_PRELOADED_DTB_BASE at build time.

Andre Przywara 40a0de1972 arm_fpga: Remove SPE PMU DT node if SPE is not available
The Statistical Profiling Extension (SPE) is an architectural feature we
can safely detect at runtime. However it still relies on one piece of
platform-specific information: the interrupt line it is connected
to. This requires SPE to be described in a devicetree node.

Since SPE support varies with the CPU cores found on an FPGA image, we
should detect the presence of SPE at runtime, and remove a potentially
existing SPE PMU node from the DT.

This allows to always have the SPE node in a generic devicetree file,
without risking exposing it on a CPU without this feature.

Andre Przywara 283e5595af arm_fpga: Adjust GICR size in DT to match number of cores
The size of a GICv3 redistributor region depends on the number of
cores in the system. For the ARM FPGA port, we detect the topology at
runtime, and adjust the CPU DT nodes accordingly.
Now the size of the GICR region must also be adjusted, or Linux will
fail to initialise the GICv3.

Use the newly introduced function to overwrite the GICR size entry in
the GICv3 reg property. We count the number of existing cores by
iterating over the GICR frames until we find the LAST bit set in TYPER.

Javier Almansa Sobrino 1994e56221 arm_fpga: Add support for unknown MPIDs
This patch allows the system to fallback to a default CPU library
in case the MPID does not match with any of the supported ones.

This feature can be enabled by setting SUPPORT_UNKNOWN_MPID build
option to 1 (enabled by default only on arm_fpga platform).

This feature can be very dangerous on a production image and
therefore it MUST be disabled for Release images.

At the moment BL31 dynamically discovers the CPU topology of an FPGA
system at runtime, but does not export it to the non-secure world.
Any BL33 user would typically looks at the devicetree to learn about
existing CPUs.

This patch exports a minimum /cpus node in a devicetree to satisfy
the binding. This means that no cpumaps or caches are described.
This could be added later if needed.

An existing /cpus node in the DT will make the code bail out with a
message.

Manish Pandey 990d972f1b plat/arm: enable support for Plat owned SPs
For Arm platforms SPs are loaded by parsing tb_fw_config.dts and
adding them to SP structure sequentially, which in-turn is appended to
loadable image list.

With recently introduced dualroot CoT for SPs where they are owned
either by SiP or by Platform. SiP owned SPs index starts at SP_PKG1_ID
and Plat owned SPs index starts at SP_PKG5_ID. As the start index of SP
depends on the owner, there should be a mechanism to parse owner of a SP
and put it at the correct index in SP structure.

This patch adds support for parsing a new optional field "owner" and
based on it put SP details(UUID & Load-address) at the correct index in
SP structure.

There was a collision between the name of the typedef in the CASSERT and
something else, so we make the name of the typedef unique to the
invocation of DEFFINE_SVC_UUID2 by appending the name that's passed into
the macro. This eliminates the following MISRA violation:

    bl1/bl1_main.c:233:[MISRA C-2012 Rule 5.6 (required)] Identifier
    "invalid_svc_uuid" is already used to represent a typedef.

This also resolves MISRA rule 5.9.

These renamings are as follows:
  * tzram -> secram. This matches the function call name as it has
  sec_mem in it's  name
  * fw_config_base -> config_base. This file does not mess with
  hw_conig, so there's little chance of confusion

Manish Pandey 03a5225c6a tbbr/dualroot: rename SP package certificate file
Currently only single signing domain is supported for SP packages but
there is plan to support dual signing domains if CoT is dualroot.

SP_CONTENT_CERT_ID is the certificate file which is currently generated
and signed with trusted world key which in-turn is derived from Silicon
provider RoT key.
To allow dual signing domain for SP packages, other certificate file
will be derived from Platform owned RoT key.

This patch renames "SP_CONTENT_CERT_ID" to "SIP_SP_CONTENT_CERT_ID" and
does other related changes.

Andre Przywara fa30f73b37 arm_fpga: Support uploading a custom command line
The command line for BL33 payloads is typically taken from the DTB. On
"normal" systems the bootloader will put the right version in there, but
we typically don't use one on the FPGAs.
To avoid editing (and possibly re-packaging) the DTB for every change in
the command line, try to read it from some "magic" memory location
instead. It can be easily placed there by the tool that uploads the
other payloads to the FPGA's memory. BL31 will then replace the existing
command line in the DTB with that new string.

To avoid reading garbage, check the memory location for containing a
magic value. This is conveniently chosen to be a simple ASCII string, so
it can just preceed the actual command line in a text file:
--------------------------------
CMD:console=ttyAMA0,38400n8 debug loglevel=8
--------------------------------
