Pali Rohár ff46a41dc2 docs: marvell: Replace ESPRESSObin-Ultra TF-A build example by full example how to build production release of Marvell firmware image
ESPRESSObin-Ultra TF-A build example was now just a copy+paste of previous
mentioned example. It produced debug binary with custom log level, which
was not described. So rather replace this duplicate build example by a full
example with all steps how to build production release of Marvell firmware
image for EspressoBin with 1GHz CPU and 1GB DDR4 RAM.

Pali Rohár 711a6bb79b docs: marvell: Update info about WTMI_IMG option
Default WTMI_IMG value was documented incorrectly. Also WTMI_IMG name may
be misleading as this option does not specify full WTMI image, just a main
loop (e.g. fuse.bin or custom RTOS image) without hardware initialization
code (DDR, CPU and clocks).

Pali Rohár 8b92097366 plat: marvell: armada: a3k: Add a new target mrvl_uart which builds UART image
This change separates building of flash and UART images, so it is possible
to build only one of these images. Also this change allows make to build
them in parallel.

Target mrvl_flash now builds only flash image and mrvl_uart only UART
image. This change reflects it also in the documentation.

Pali Rohár 8708a884ae plat: marvell: armada: a3k: Allow use of the system Crypto++ library
This change introduces two new A3720 parameters, CRYPTOPP_LIBDIR and
CRYPTOPP_INCDIR, which can be used to specify directory paths to
pre-compiled Crypto++ library and header files.

When both new parameters are specified then the source code of Crypto++ via
CRYPTOPP_PATH parameter is not needed. And therefore it allows TF-A build
process to use system Crypto++ library.

Marek Behún d9243f264b plat: marvell: armada: a3k: support doing system reset via CM3 secure coprocessor
Introduce a new build option CM3_SYSTEM_RESET for A3700 platform, which,
when enabled, adds code to the PSCI reset handler to try to do system
reset by the WTMI firmware running on the Cortex-M3 secure coprocessor.
(This function is exposed via the mailbox interface.)

The reason is that the Turris MOX board has a HW bug which causes reset
to hang unpredictably. This issue can be solved by putting the board in
a specific state before reset.

Javier Almansa Sobrino 0063dd1708 Add support for FEAT_MTPMU for Armv8.6
If FEAT_PMUv3 is implemented and PMEVTYPER<n>(_EL0).MT bit is implemented
as well, it is possible to control whether PMU counters take into account
events happening on other threads.

If FEAT_MTPMU is implemented, EL3 (or EL2) can override the MT bit
leaving it to effective state of 0 regardless of any write to it.

This patch introduces the DISABLE_MTPMU flag, which allows to diable
multithread event count from EL3 (or EL2). The flag is disabled
by default so the behavior is consistent with those architectures
that do not implement FEAT_MTPMU.

Jimmy Brisson 831b0e9824 Don't return error information from console_flush
And from crash_console_flush.

We ignore the error information return by console_flush in _every_
place where we call it, and casting the return type to void does not
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.

Cortex A77 erratum 1925769 is a Cat B erratum, present in older
revisions of the Cortex A77 processor core.  The workaround is to
set bit 8 in the ECTLR_EL1 register, there is a small performance cost
(<0.5%) for setting this bit.

- Added detection of AMUv1 for ARMv8.6
- 'PLAT_AMU_GROUP1_NR_COUNTERS' build option is removed and
number of group1 counters 'AMU_GROUP1_NR_COUNTERS' is now
calculated based on 'AMU_GROUP1_COUNTERS_MASK' value
- Added bit fields definitions and access functions for
AMCFGR_EL0/AMCFGR and AMCGCR_EL0/AMCGCR registers
- Unification of amu.c Aarch64 and Aarch32 source files
- Bug fixes and TF-A coding style compliant changes.

Grant Likely 29214e95c4 Use abspath to dereference $BUILD_BASE
If the user tries to change BUILD_BASE to put the build products outside
the build tree the compile will fail due to hard coded assumptions that
$BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE))
to rationalize to an absolute path every time and remove the relative
path assumptions.

This patch also adds documentation that BUILD_BASE can be specified by
the user.

Manish V Badarkhe 6f0a2f04ab SMCCC: Introduce function to check SMCCC function availability
Currently, 'SMCCC_ARCH_FEATURES' SMC call handler unconditionally
returns 'SMC_OK' for 'SMCCC_ARCH_SOC_ID' function. This seems to
be not correct for the platform which doesn't implement soc-id
functionality i.e. functions to retrieve both soc-version and
soc-revision.
Hence introduced a platform function which will check whether SMCCC
feature is available for the platform.

Also, updated porting guide for the newly added platform function.

Cortex A76 erratum 1800710 is a Cat B erratum, present in older

Andre Przywara b4ad365a46 GICv3: GIC-600: Detect GIC-600 at runtime
The only difference between GIC-500 and GIC-600 relevant to TF-A is the
differing power management sequence.
A certain GIC implementation is detectable at runtime, for instance by
checking the IIDR register. Let's add that test before initiating the
GIC-600 specific sequence, so the code can be used on both GIC-600 and
GIC-500 chips alike, without deciding on a GIC chip at compile time.

This means that the GIC-500 "driver" is now redundant. To allow minimal
platform support, add a switch to disable GIC-600 support.

Usama Arif f5c58af653 plat/arm: Introduce TC0 platform
This patch adds support for Total Compute (TC0) platform. It is an
initial port and additional features are expected to be added later.

TC0 has a SCP which brings the primary Cortex-A out of reset
which starts executing BL1. TF-A optionally authenticates the SCP
ram-fw available in FIP and makes it available for SCP to copy.

Some of the major features included and tested in this platform
port include TBBR, PSCI, MHUv2 and DVFS.

johpow01 6cac724d52 Enable v8.6 WFE trap delays
This patch enables the v8.6 extension to add a delay before WFE traps
are taken. A weak hook plat_arm_set_twedel_scr_el3 has been added in
plat/common/aarch64/plat_common.c that disables this feature by default
but platform-specific code can override it when needed.

The only hook provided sets the TWED fields in SCR_EL3, there are similar
fields in HCR_EL2, SCTLR_EL2, and SCTLR_EL1 to control WFE trap delays in
lower ELs but these should be configured by code running at EL2 and/or EL1
depending on the platform configuration and is outside the scope of TF-A.

Manish V Badarkhe 45aecff003 Implement workaround for AT speculative behaviour
During context switching from higher EL (EL2 or higher)
to lower EL can cause incorrect translation in TLB due to
speculative execution of AT instruction using out-of-context
translation regime.

Workaround is implemented as below during EL's (EL1 or EL2)
"context_restore" operation:
1. Disable page table walk using SCTLR.M and TCR.EPD0 & EPD1
   bits for EL1 or EL2 (stage1 and stage2 disabled)
2. Save all system registers except TCR and SCTLR (for EL1 and EL2)
3. Do memory barrier operation (isb) to ensure all
   system register writes are done.
4. Restore TCR and SCTLR registers (for EL1 and EL2)

Errata details are available for various CPUs as below:
Cortex-A76: 1165522
Cortex-A72: 1319367
Cortex-A57: 1319537
Cortex-A55: 1530923
Cortex-A53: 1530924

More details can be found in mail-chain:
https://lists.trustedfirmware.org/pipermail/tf-a/2020-April/000445.html

disabled.

The maintainers.rst file provides the list of all TF-A modules and their

Introduce categories (core code, drivers/libraries/framework, ...) and
classify each module in the right one.

Note that the core code category is pretty much empty right now but the
plan would be to expand it with further modules (e.g. PSCI, SDEI, TBBR,
...) in a future patch.

Alexei Fedorov a6ea06f563 TF-A GICv3 driver: Introduce makefile
This patch moves all GICv3 driver files into new added
'gicv3.mk' makefile for the benefit of the generic driver
which can evolve in the future without affecting platforms.
The patch adds GICv3 driver configuration flags
'GICV3_IMPL', 'GICV3_IMPL_GIC600_MULTICHIP' and
'GICV3_OVERRIDE_DISTIF_PWR_OPS' described in
'GICv3 driver options' section of 'build-option.rst'
document.

NOTE: Platforms with GICv3 driver need to be modified to
include 'drivers/arm/gic/v3/gicv3.mk' in their makefiles.

Louis Mayencourt a6de824f7e fconf: Clean Arm IO
Merge the previously introduced arm_fconf_io_storage into arm_io_storage. This
removes the duplicate io_policies and functions definition.

This patch:
- replace arm_io_storage.c with the content of arm_fconf_io_storage.c
- rename the USE_FCONF_BASED_IO option into ARM_IO_IN_DTB.
- use the ARM_IO_IN_DTB option to compile out io_policies moved in dtb.
- propagate DEFINES when parsing dts.
- use ARM_IO_IN_DTB to include or not uuid nodes in fw_config dtb.
- set the ARM_IO_IN_DTB to 0 by default for fvp. This ensure that the behavior
  of fvp stays the same as it was before the introduction of fconf.
