Move the data section to the common header.
I slightly tweaked some scripts as follows:
[1] bl1.ld.S has ALIGN(16). I added DATA_ALIGN macro, which is 1
by default, but overridden by bl1.ld.S. Currently, ALIGN(16)
of the .data section is redundant because commit 4128659076
("Fix boot failures on some builds linked with ld.lld.") padded
out the previous section to work around the issue of LLD version
<= 10.0. This will be fixed in the future release of LLVM, so
I am keeping the proper way to align LMA.
[2] bl1.ld.S and bl2_el3.ld.S define __DATA_RAM_{START,END}__ instead
of __DATA_{START,END}__. I put them out of the .data section.
[3] SORT_BY_ALIGNMENT() is missing tsp.ld.S, sp_min.ld.S, and
mediatek/mt6795/bl31.ld.S. This commit adds SORT_BY_ALIGNMENT()
for all images, so the symbol order in those three will change,
but I do not think it is a big deal.

We simulate the PSCI CPU_OFF operation by reseting the core via RMR.
For secondaries, that already puts them in the holding pen waiting for a
"warm boot" request as part of PSCI CPU_ON. For the BSP, we have to add
logic to distinguish a regular boot from a CPU_OFF state, where, like the
secondaries, the BSP needs to wait foor a "warm boot" request as part
of CPU_ON.
Testing done:
- ACS suite now passes more tests (since it repeatedly
calls code on secondaries via CPU_ON).
- Linux testing including offlining/onlineing CPU0, e.g.
"echo 0 > /sys/devices/system/cpu/cpu0/online".

When writing to arbitrary locations in memory using a constructed

BL31 behaves differently depending on whether or not the CPUs in the

regard.
This compiles a different set of CPU libraries depending on whether or

This allows the BL31 port to run with position-independent execution
enabled so that it can be ran from any address in the system.
This increases the flexibility of the image, allowing it to be ran from
other locations rather than only its hardcoded absolute address
(currently set to the typical DRAM base of 2GB). This may be useful for
future images that describe system configurations with other memory
layouts (e.g. where SRAM is included).
It does this by setting ENABLE_PIE=1 and changing the absolute
address to 0. The load address of bl31.bin can then be specified by
the -l [load address] argument in the fpga-run command (additionally,
this address is required by any preceding payloads that specify the
start address. For ELF payloads this is usually extracted automatically
by reading the entrypoint address in the header, however bl31.bin is a
different file format so has this additional dependency).

This change is part of the goal of enabling the port to be compatible
with multiple FPGA images.
The BL31 port that is uploaded as a payload to the FPGA with an image
should cater for a wide variety of system configurations. This patch
makes the necessary changes to enable it to function with images whose
cluster configurations may be larger (either by utilizing more
clusters, more CPUs per cluster, more threads in each CPU, or a
combination) than the initial image being used for testing.
As part of this, the hard-coded values that configure the size of the
array describing the topology of the power domain tree are increased
to max. 8 clusters, max. 8 cores per cluster & max 4 threads per core.
This ensures the port works with cluster configurations up to these
sizes. When there are too many entries for the number of available PEs,
e.g. if there is a variable number of CPUs between clusters, then there
will be empty entries in the array. This is permitted and the PSCI
library will still function as expected. While this increases its size,
this shouldn't be an issue in the context of the size of BL31, and is
worth the trade-off for the extra compatibility.

This adds a basic PSCI implementation allow secondary CPUs to be
released from an initial state and continue through to the warm boot
entrypoint.
Each secondary CPU is kept in a holding pen, whereby it polls the value
representing its hold state, by reading this from an array that acts as
a table for all the PEs. The hold states are initially set to 0 for all
cores to indicate that the executing core should continue polling.
To prevent the secondary CPUs from interfering with the platform's
initialization, they are only updated by the primary CPU once the cold
boot sequence has completed and fpga_pwr_domain_on(mpidr) is called.
The polling target CPU will then read 1 (which indicates that it should
branch to the warm reset entrypoint) and then jump to that address
rather than continue polling.
In addition to the initial polling behaviour of the secondary CPUs
before their warm boot reset sequence, they are also placed in a
low-power wfe() state at the end of each poll; accordingly, the PSCI
fpga_pwr_domain_on(mpidr) function also signals an event to all cores
(after updating the target CPU's hold entry) to wake them from this
state, allowing any secondary CPUs that are still polling to check
their hold state again.
This method is in accordance with both the PSCI and Linux kernel
recommendations, as the lessened overhead reduces the energy
consumption associated with the busy-loop.
The table of hold entries is implemented by a global array as shared SRAM
(which is used by other platforms in similar implementations) is not
available on the FPGA images.

This makes use of the PRELOADED_BL33_BASE flag to indicate to BL31 that
the BL33 payload (kernel) has already been loaded and resides in memory;
BL31 will then jump to the non-secure address.
For this port the BL33 payload is the Linux kernel, and in accordance
with the pre-kernel setup requirements (as specified in the `Booting
AArch64 Linux' documentation:
https://www.kernel.org/doc/Documentation/arm64/booting.txt),
this change also sets up the primary CPU's registers x0-x3 so they are
the expected values, which includes the address of the DTB at x0.
An external linker script is currently required to combine BL31, the
BL33 payload, and any other software images to create an ELF file that
can be uploaded to the FPGA board along with the bit file. It therefore
has dependencies on the value of PRELOADED_BL33_BASE (kernel base) and

Arm, such that BL31 runs as a payload for an image.
Future changes will enable the port for a wide range of system

It is expected that this will replace the FPGA fork of the Linux kernel
bootwrapper by performing similar secure-world initialization and setup
through the use of drivers and other well-established methods, before
passing control to the kernel, which will act as the BL33 payload and
run in EL2NS.

This function gets the DDR size from DT, and withdraws (if defined) the
sizes of secure DDR and shared memory areas.
This function also checks DT values fits the default DDR range.
This non-secure memory is available for BL33 and non-secure OS.

This patch increases the maximum timeout value for SE operation
completion to 1 second. This takes care of some corner cases where
an operation might take more time than the previous timeout value
of 100ms.

When SPD=spmd and SPMD_SPM_AT_SEL2=0, that is SPMC sits at S-EL1
then there is no need for TF-A to load secure partitions individually.
In this configuration, SPMC handles secure partition loading at
S-EL1/EL0 levels.

Correct the following sparse warnings:
plat/st/common/stm32mp_dt.c:103:5: warning:
symbol 'fdt_get_node_parent_address_cells' was not declared.
Should it be static?
plat/st/common/stm32mp_dt.c:123:5: warning:
symbol 'fdt_get_node_parent_size_cells' was not declared.
Should it be static?
As those 2 functions are only used by assert(), put them under
ENABLE_ASSERTIONS flag.

1. This removes hardcoded iomux/clk/addr configuration for debug uart,
provides possibility (as a workaround, till that information isn't
provided via DT) to set this configuration during compile time via
IMX_DEBUG_UART build flag.
Also for Colibri i.MX8QXP different pinmux configuration is applied
for UART3, FLEXCAN2_RX/TX pads are muxed to ADMA_UART3_RX/TX.
2. Having DEBUG_CONSOLE enabled without enabling DEBUG_CONSOLE_A35
doesn't make sense (since UART pinmux/clock configuration is applied
for UART only when DEBUG_CONSOLE_A35 is enabled. Check similar commit
for i.MX8QM 98a69dfd4a("plat: imx: imx8qm: apply clk/pinmux
configuration for DEBUG_CONSOLE")).
Usage:
$ make PLAT=imx8qx IMX_DEBUG_UART=3 DEBUG_CONSOLE=1 bl31

The base address for both the GPIO and the clock unit of the H6 memory map
have been typo-ed. Fix them to match the Linux DT and the manual.
The H6 code use neither of them, so this doesn't change or fix anything
in the real world, but should be corrected anyway.
The issue was found and reported by Github user "armlabs".

MISRA rules request that the cluster and CPU counter be unsigned
values and have a suffix 'U'. If the define located in the makefile,
this cannot be done.
This patch moves the PLATFORM_CLUSTER_COUNT and PLATFORM_MAX_CPUS_PER_CLUSTER
macros to tegra_def.h as a result.

Hotplug poweron is not working for boot CPU as it's being
triggerred using PMC and not with Flow Controller. This is
happening because "cpu_powergate_mask" is only getting set
for non-boot CPU's as the boot CPU's first bootup follows
different code path. The patch is marking a CPU as ON within
"cpu_powergate_mask" when turning its power domain on
during power on. This will ensure only first bootup on all
CPU's is using PMC and subsequent hotplug poweron will be
using Flow Controller.
