Madhukar Pappireddy 10640d2459 Merge "GICv3: GIC-600: Detect GIC-600 at runtime" into integration 2020-06-09 20:17:39 +00:00
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.

Manish Pandey 44f1aa8efe dualroot: add chain of trust for secure partitions
A new certificate "sip-sp-cert" has been added for Silicon Provider(SiP)
owned Secure Partitions(SP). A similar support for Platform owned SP can
be added in future. The certificate is also protected against anti-
rollback using the trusted Non-Volatile counter.

To avoid deviating from TBBR spec, support for SP CoT is only provided
in dualroot.
Secure Partition content certificate is assigned image ID 31 and SP
images follows after it.

The CoT for secure partition look like below.

Grzegorz Jaszczyk c3c51b3283 plat: marvell: ap807: update configuration space of each CP
By default all external CPs start with configuration address space set to
0xf200_0000. To overcome this issue, go in the loop and initialize the
CP one by one, using temporary window configuration which allows to access
each CP and update its configuration space according to decoding
windows scheme defined for each platform.

In case of cn9130 after this procedure bellow addresses will be used:
CP0 - f2000000
CP1 - f4000000
CP2 - f6000000

When the re-configuration is done there is need to restore previous
decoding window configuration(init_io_win).

Etienne Carriere 45c70e6867 drivers: stm32_reset adapt interface to timeout argument
Changes stm32mp1 reset driver to API to add a timeout argument
to stm32mp_reset_assert() and stm32mp_reset_deassert() and
a return value.

With a supplied timeout, the functions wait the target reset state
is reached before returning. With a timeout of zero, the functions
simply load target reset state in SoC interface and return without
waiting.

Helper functions stm32mp_reset_set() and stm32mp_reset_release()
use a zero timeout and return without a return code.

This change updates few stm32 drivers and plat/stm32mp1 blé_plat_setup.c
accordingly without any functional change.

Andre Przywara 52a616b48c plat/stm32: Use generic fdt_read_uint32_array() implementation
The device tree parsing code for the STM32 platform is using its own FDT
helper functions, some of them being rather generic.
In particular the existing fdt_read_uint32_array() implementation is now
almost identical to the new generic code in fdt_wrappers.c, so we can
remove the ST specific version and adjust the existing callers.

Compared to the original ST implementation the new version takes a
pointer to the DTB as the first argument, and also swaps the order of
the number of cells and the pointer.

Andre Przywara ac71344e9e console: Integrate UART base address in generic console_t
*All* UART drivers in TF-A are storing their base address as a uintptr_t
pointer in the first location of the UART specific driver data.
Since the base address is a pretty natural and generic data item, we
should integrate this into the generic console_t structure.

That will not only allow to remove a lot of seemingly UART specific data
structures, but also enables to simplify runtime choices between different
UARTs, since they can share the same pointer.

This patch just adds the new member, the existing data structures will
be handled on a per-UART base in follow-up patches.

Aditya Angadi 31e703f995 drivers/arm/scmi: allow use of multiple SCMI channels
On systems that have multiple platform components that can interpret the
SCMI messages, there is a need to support multiple SCMI channels (one
each to those platform components). Extend the existing SCMI interface
that currently supports only a single SCMI channel to support multiple
SCMI channels.

Aditya Angadi f893160690 drivers/mhu: derive doorbell base address
In order to allow the MHUv2 driver to be usable with multiple MHUv2
controllers, use the base address of the controller from the platform
information instead of the MHUV2_BASE_ADDR macro.

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.

Grzegorz Jaszczyk 8164605513 plat: marvell: armada: add support for loading MG CM3 images
In order to access MG SRAM, the amb bridge needs to be configured which is
done in bl2 platform init.

For MG CM3, the image is only loaded to its SRAM and the CM3 itself is
left in reset. It is because the next stage bootloader (e.g. u-boot)
will trigger action which will take it out of reset when needed. This
can happen e.g. when appropriate device-tree setup (which has enabled
802.3 auto-neg) will be chosen. In other cases the MG CM3 should not be
running.
