Varun Wadekar 8f0e22d560 Tegra194: SiP function ID to read SMMU_PER registers
This patch introduces SiP function ID, 0xC200FF00, to read SMMU_PER
error records from all supported SMMU blocks.

The register values are passed over to the client via CPU registers
X1 - X3, where

X1 = SMMU_PER[instance #1] | SMMU_PER[instance #0]
X2 = SMMU_PER[instance #3] | SMMU_PER[instance #2]
X3 = SMMU_PER[instance #5] | SMMU_PER[instance #4]

Olivier Deprez 3d5ed6dee2 spmc: manifest changes to support two sample cactus secure partitions
When using the SPM Dispatcher, the SPMC sits as a BL32 component
(BL32_IMAGE_ID). The SPMC manifest is passed as the TOS fw config
component (TOS_FW_CONFIG_ID). It defines platform specific attributes
(memory range and physical CPU layout) as well as the attributes for
each secure partition (mostly load address). This manifest is passed
to the SPMC on boot up. An SP package contains the SP dtb in the SPCI
defined partition manifest format. As the SPMC manifest was enriched
it needs an increase of tos_fw-config max-size in fvp_fw_config dts.

This patch converts the 'plat_core_pos_by_mpidr' handler into an assembly

PROGBITS, the max size of BL31 image is increased by 0x1000(4K).

Andre Przywara 9cc3fa1b8a rpi: console: Autodetect Mini-UART vs. PL011 configuration
The Raspberry Pi has two different UART devices pin-muxed to GPIO 14&15:
One ARM PL011 one and the 8250 compatible "Mini-UART".
A dtoverlay parameter in config.txt will tell the firmware to switch
between the two: it will setup the right clocks and will configure the
pinmuxes accordingly.

To autodetect the user's choice, we read the pinmux register and check
its setting: ALT5 (0x2) means the Mini-UART is used, ALT0 (0x4) points
to the PL011.
Based on that we select the UART driver to initialise.

This will allow console output in any case.

So far the Raspberry Pi 3 build needs the GPIO driver just for BL2.
Upcoming changes will require some GPIO code in BL1 and BL31 also, so
move those driver files into the common source section.

This does not affect BL31 code size at all, and bl1.bin just increases
by 144 bytes, but doesn't affect the padded binary size at all.

Andre Przywara 5e6d821cb3 rpi: Allow using PL011 UART for RPi3/RPi4
The Broadcom 283x SoCs feature multiple UARTs: the mostly used
"Mini-UART", which is an 8250 compatible IP, and at least one PL011.
While the 8250 is usually used for serial console purposes, it suffers
from a design flaw, where its clock depends on the VPU clock, which can
change at runtime. This will reliably mess up the baud rate.
To avoid this problem, people might choose to use the PL011 UART for
the serial console, which is pin-mux'ed to the very same GPIO pins.
This can be done by adding "miniuart-bt" to the "dtoverlay=" line in
config.txt.

To prepare for this situation, use the newly gained freedom of sharing
one console_t pointer across different UART drivers, to introduce the
option of choosing the PL011 for the console.

This is for now hard-coded to choose the Mini-UART by default.
A follow-up patch will introduce automatic detection.

In the wake of the upcoming unification of the console setup code

RPi3. This avoid programming any clocks or baud rate registers,
which makes the port more robust against GPU firmware changes.

Andre Przywara 0d92745e10 rpi3: gpio: Simplify GPIO setup
There is really no reason to use and pass around a struct when its only
member is the (fixed) base address.

Remove the struct and just use the base address on its own inside the
GPIO driver. Then set the base address automatically.

This simplifies GPIO setup for users, which now don't need to deal with
zeroing a struct and setting the base address anymore.

Madhukar Pappireddy 6138ffbc12 plat/arm/fvp: populate pwr domain descriptor dynamically
The motivation behind this patch and following patches is to extract
information about the platform in runtime rather than depending on
compile time macros such as FVP_CLUSTER_COUNT. This partially enables
us to use a single binary for a family of platforms which all have
similar hardware capabilities but differ in configurations.

we populate the data structure describing the power domain hierarchy
of the platform dynamically by querying the number of clusters and cpus
using fconf getter APIs. Compile time macro such as FVP_CLUSTER_COUNT
is still needed as it determines the size of related data structures.

Note that the cpu-map node in HW_CONFIG dts represents a logical
hierarchy of power domains of CPU. However, in reality, the power
domains may not have been physically built in such hierarchy.

Kalyani Chidambaram b8dbf07374 Tegra210: Remove "unsupported func ID" error msg
The platform sip is reporting a "unsupported function ID" if the
smc function id is not pmc command. When actually the smc function id
could be specific to the tegra sip handler.
This patch removes the error reported.

Pritesh Raithatha a391d4942a Tegra: smmu: remove context save sequence
SMMU and MC registers are saved as part of the System Suspend sequence.
The register list includes some NS world SMMU registers that need to be
saved by NS world software instead. All that remains as a result are
the MC registers.

This patch moves code to MC file as a result and renames all the
variables and defines to use the MC prefix instead of SMMU. The
Tegra186 and Tegra194 platform ports are updated to provide the MC
context register list to the parent driver. The memory required for
context save is reduced due to removal of the SMMU registers.

Pritesh Raithatha de3fd9b3bb Tegra194: memctrl: lock some more MC SID security configs
The platform code already contains the initial set of MC SID
security configs to be locked during boot. This patch adds some
more configs to the list. Since the reset value of these registers
is already as per expectations, there is no need to change it.

MC SID security configs
- PTCR,
- MIU6R, MIU6W, MIU7R, MIU7W,
- MPCORER, MPCOREW,
- NVDEC1SRD, NVDEC1SRD1, NVDEC1SWR.

Jeetesh Burman 029dd14e72 Tegra194: add SE support to generate SHA256 of TZRAM
The BL3-1 firmware code is stored in TZSRAM on Tegra194 platforms. This
memory loses power when we enter System Suspend and so its contents are
stored to TZDRAM, before entry. This opens up an attack vector where the
TZDRAM contents might be tampered with when we are in the System Suspend
mode. To mitigate this attack the SE engine calculates the hash of entire
TZSRAM and stores it in PMC scratch, before we copy data to TZDRAM. The
WB0 code will validate the TZDRAM and match the hash with the one in PMC
scratch.

This patch adds driver for the SE engine, with APIs to calculate the hash
and store to PMC scratch registers.

Madhukar Pappireddy 4682461ded fconf: Extract topology node properties from HW_CONFIG dtb
Create, register( and implicitly invoke) fconf_populate_topology()
function which extracts the topology related properties from dtb into
the newly created fconf based configuration structure 'soc_topology'.
Appropriate libfdt APIs are added to jmptbl.i file for use with USE_ROMLIB
build feature.

A new property which describes the power domain levels is added to the
HW_CONFIG device tree source files.

This patch also fixes a minor bug in the common device tree file
fvp-base-gicv3-psci-dynamiq-common.dtsi
As this file includes fvp-base-gicv3-psci-common.dtsi, it is necessary
to delete all previous cluster node definitons because DynamIQ based
models have upto 8 CPUs in each cluster. If not deleted, the final dts
would have an inaccurate description of SoC topology, i.e., cluster0
with 8 or more core nodes and cluster1 with 4 core nodes.
