Pali Rohár 0d06b058a5 marvell: uart: a3720: Increase TX FIFO EMPTY timeout from 2ms to 3ms
TX FIFO has space for 32 characters. With default UART baudrate 115200 it
takes more than 2ms to transmit all 32 characters, so wait at least 3ms
before flushing TX FIFO.

If WTMI firmware transmitted something via UART before TF-A was booted,
some characters may still wait in TX FIFO when TF-A is initializing UART
driver. So wait at least 3ms to ensure that HW has enough time to transmit
all characters waiting in TX FIFO.

This fixes an issue where sometimes characters transmitted on UART by our
custom WTMI image are lost.

Console initialization function needs to wait at least minimal specified

wait at least for 100 us on 1200 MHz variant too. The slowest Armada 3720
CPU is 600 MHz and in this case delay loop would take just 2 times more,
which is not a problem.

it can't get the real filter number to construct the bit flag for all

FILTER_BIT_ALL to tzc400_configure_region() will cause assertion or
misconfiguration. So adjust the bit flag against the real filter

In function gicv3_spis_config_defaults(), the variable num_ints is set

logical bug in the "for" loops, for the INTID of num_eints is also
valid and the check should be inclusive.

Fix this by setting num_eints to (maximum ESPI INTID + 1) as well.

Heyi Guo deb18901d1 drivers/gicv3: fix potential GICD context override with ESPI enabled
RESTORE/SAVE_GICD_EREGS uses (int_id - (MIN_ESPI_ID - MIN_SPI_ID)) to
get the context array index for ESPI, which will override the space of
standard SPI starting from (MIN_SPI_ID + MIN_SPI_ID).

However, using TOTAL_SPI_INTR_NUM to replace the above MIN_SPI_ID
cannot totally fix the issue, for TOTAL_SPI_INTR_NUM is not well
aligned and the array index will be rounded down by the shifting
operation if being shifted more than 2 bits. It will cause buffer
override again when the existing maximum SPI reaches 1019.

So round up TOTAL_SPI_INTR_NUM with (1 << REG##R_SHIFT) for GICD
context arrays.

Heyi Guo 60cd8030bf drivers/gicv3: use mpidr to probe GICR for current CPU
In function gicv3_rdistif_probe(), line #1322 implies
gicv3_driver_data->mpidr_to_core_pos() may be null, but the original
code uses this interface to get current CPU index unconditionally.

It is better to use MPIDR to probe GICR which does not depend on
gicv3_driver_data->mpidr_to_core_pos().

Pali Rohár b8e637f49e marvell: uart: a3720: Fix macro name for 6th bit of Status Register
This patch does not change code, it only updates comments and macro name
for 6th bit of Status Register. So TF-A binary stay same.

6th bit of the Status Register is named TX EMPTY and is set to 1 when both
Transmitter Holding Register (THR) or Transmitter Shift Register (TSR) are
empty. It is when all characters were already transmitted.

There is also TX FIFO EMPTY bit in the Status Register which is set to 1
only when THR is empty.

In both console_a3700_core_init() and console_a3700_core_flush() functions
we should wait until both THR and TSR are empty therefore we should check
6th bit of the Status Register.

So current code is correct, just had misleading macro names and comments.
This change fixes this "documentation" issue, fixes macro name for 6th bit
of the Status Register and also updates comments.

Michal Simek 0b3d4273fa cadence: Change logic in uart driver
Write char if fifo is empty. If this is done like this all chars are
printed. Because origin code just put that chars to fifo and in case of
reset messages were missing.

Before this change chars are put to fifo and only check before adding if
fifo is full. The patch is changing this logic that it is adding char only
when fifo is empty to make sure that in case of reset (by another SW for
example) all chars are printed. Maybe one char can be missed but for IP
itself it is much easier to send just one char compare to full fifo.

Marek Vasut 605767475e rcar_gen3: drivers: console: Treat log as device memory
The BL31 log driver is registered before the xlat tables are initialized,
at that point the log memory is configured as device memory and can only
be accessed with up-to-32bit aligned accesses. Adjust the driver to do
just that.

The memset() call has to be replaced by a loop of 32bit writes to the log,
the memcpy() is trivial to replace with a single 32bit write of the entire
TLOG word. In the end, this even simplifies the code.

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.

johpow01 20d384978b Fix casting bug in gicv2_main.c
In the function gicv2_set_spi_routing, the signed value proc_num is cast
to unsigned int before being compared to other unsigned values in two
assert calls.  The value proc_num can be a negative value, and once the
negative value is cast to unsigned it becomes a very large number which
will trigger the assert.  This patch changes the assert cast so that the
unsigned values are cast to signed instead, keeping the same functionality
but allowing proc_num to be negative.

This bug can be seen when running the SDEI RM_ANY routing mode test in
TFTF on the Juno platform.

This patch also makes the usage of the proc_num variable in other gicv2
functions more clear.

A GICv3 interrupt controller will be instantiated for a certain number
of cores. This will result in the respective number of GICR frames. The
last frame will have the "Last" bit set in its GICR_TYPER register.

For platforms with a topology unknown at build time (the Arm FPGAs, for
instance), we need to learn the number of used cores at runtime, to size
the GICR region in the devicetree accordingly.

Add a generic function that iterates over all GICR frames until it
encounters one with the "Last" bit set. It returns the number of cores
the GICv3 has been configured for.

Andre Przywara 93fa305c0a plat/allwinner: Only enable DRIVEVBUS if really needed
The DRIVEVBUS power rail of the AXP803 PMIC is mostly used to supply
the USB bus power on micro USB sockets, when used in host mode. As this
is a dynamic operation, and mostly we want micro USB sockets to act in
client mode initially, BL31 should not actually enable this power line.
However, on some boards DRIVEVBUS is used to supply power to normal
USB-A sockets. Failing to activate this line there results in
non-functional USB in U-Boot on those boards.

For that reason we were enabling DRIVEVBUS so far, as it did not seem to
cause any harm to the other boards. However it turns out that on the
Pinephone (and other systems with a battery), actually enabling DRIVEVBUS
unconditionally causes serious problems (reboot loop).

To accommodate both use cases, without reverting to a build time option,
check the default OTG configuration in the devicetree. For boards with
USB-A sockets this is set to "host", on boards with micro-B sockets to
"otg". Depending on this setting, we either enable DRIVEVBUS or leave it
alone.

This fixes TF-A on the Pinephone and potentially other battery powered
devices.

Sandeep Tripathy 5eb16c4717 TF-A GIC driver: Add barrier before eoi
It is desired to have the peripheral writes completed to clear the
interrupt condition and de-assert the interrupt request to GIC before
EOI write. Failing which spurious interrupt will occurred.

A barrier is needed to ensure peripheral register write transfers are
complete before EOI is done.

GICv2 memory mapped DEVICE nGnR(n)E writes are ordered from core point
of view. However these writes may pass over different interconnects,
bridges, buffers leaving some rare chances for the actual write to
complete out of order.

GICv3 ICC EOI system register writes have no ordering against nGnR(n)E
memory writes as they are over different interfaces.

Hence a dsb can ensure from core no writes are issued before the previous
writes are *complete*.

Etienne Carriere 7d6fa6ecbe drivers/scmi-msg: smt entry points for incoming messages
This change implements SCMI channels for reading a SCMI message from a
shared memory and call the SCMI message drivers to route the message
to the target platform services.

SMT refers to the shared memory management protocol which is used
to get/put message/response in shared memory. SMT is a 28byte header
stating shared memory state and exchanged protocol data.

The processing entry for a SCMI message can be a secure interrupt
or fastcall SMCCC invocation.

SMT description in this implementation is based on the OP-TEE
project [1] itself based in the SCP-firmware implementation [2].

Etienne Carriere 75366ccd9b drivers/scmi-msg: driver for processing scmi messages
This change introduces drivers to allow a platform to create a basic
SCMI service and register handlers for client request (SCMI agent) on
system resources. This is the first piece of the drivers: an entry
function, the SCMI base protocol support and helpers for create
the response message.

With this change, scmi_process_message() is the entry function to
process an incoming SCMI message. The function expect the message
is already copied from shared memory into secure memory. The message
structure stores message reference and output buffer reference where
response message shall be stored.

scmi_process_message() calls the SCMI protocol driver according to
the protocol ID in the message. The SCMI protocol driver will call
defined platform handlers according to the message content.

This change introduces only the SCMI base protocol as defined in
SCMI specification v2.0 [1]. Not all the messages defined
in the specification are supported.

The SCMI message implementation is derived from the OP-TEE project [2]
itself based on the SCP-firmware implementation [3] of the SCMI protocol
server side.

Manish Pandey 68758dd60a tbbr: add chain of trust for Secure Partitions
with sha 44f1aa8, support for Silicon Provider(SiP) owned Secure
Partition(SP) was added for dualroot CoT. This patch extends this
support for tbbr CoT.

Earlier tbbr CoT for SPs was left to avoid adding new image types in
TBBR which could possibly be seen as deviation from specification.
But with further discussions it is understood that TBBR being a
*minimal* set of requirements that can be extended as long as we don't
violate any of the musts, which is the case with adding SP support.

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.

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.

Etienne Carriere 8ae08dcd19 drivers: stm32mp1 clocks: support shifted clock selector bit masks
The current implementation optimizes memory consumed by gateable
clock table by storing bit mask and bit shift with 1 byte each.
The issue is that register selector bit masks above the 7th LSBit
cannot be stored.

This change uses the shift info to shift the mask before it is used,
allowing clock selector register bit fields to be spread on the 32 bits
of the register as long as the mask fits in 8 contiguous bit at most.

This change is needed to add the RTC clock to the gateable clocks table.

The STM32 platform port parse DT nodes to find base address to
peripherals. It does this by using its own implementation, even though
this functionality is generic and actually widely useful outside of the
STM32 code.

Re-implement fdt_get_reg_props_by_name() on top of the newly introduced
fdt_get_reg_props_by_index() function, and move it to fdt_wrapper.c.
This is removes the assumption that #address-cells and #size-cells are
always one.

Remove the implementation of fdt_read_uint32_default() and implement it

all users over.

This also fixes two callers, which were slightly abusing the "default"
semantic.
