Present framework restricts platform to pass desired shareability attribute
for normal memory region mapped in MMU. it defaults to inner shareability.
There are platforms where memories (like SRAM) are not placed at snoopable
region in advaned interconnect like CCN/CMN hence snoopable transaction is
not possible to these memory. Though These memories could be mapped in MMU
as MT_NON_CACHEABLE, data caches benefits won't be available.
If these memories are mapped as cacheable with non-shareable attribute,
when only one core is running like at boot time, MMU data cached could be
used for faster execution. Hence adding support to pass the shareability
attribute for memory regions.

The platform io policies array is now always accessed through a fconf getter.
This gives us an ideal spot to check for out-of-bound accesses.
Remove the assertion in plat_get_image_source(), which is now redundant.

This is not used in BL31 or Bl32 for this platform.
Pass it to BL2_CPPFLAGS instead of defining it for all BL images.
This will produce slightly smaller BL31 and Bl32.

As GCC manual says, -D option defines a macro as 1, if =<value> is omitted.
-D <name>
Predefine <name> as a macro, with definition 1.
The same applied with Clang, too.
In the context of -D option, =1 is always redundant.

Commit d5e97a1d2c ("Build: define IMAGE_AT_EL1 or IMAGE_AT_EL3
globally for C files") does not have commit 848a7e8ce1 ("Build:
introduce per-BL CPPFLAGS and ASFLAGS") as an ancestor because
they were pulled almost at the same time.
This is a follow-up conversion to be consistent with commit
11a3c5ee73 ("plat: pass -D option to BL*_CPPFLAGS instead of
BL*_CFLAGS").
With this change, the command line option, IMAGE_AT_EL3, will be
passed to .S files as well.
I remove the definition in include/lib/cpus/aarch64/cpu_macros.S
Otherwise, the following error would happen.
include/lib/cpus/aarch64/cpu_macros.S:29:0: error: "IMAGE_AT_EL3" redefined [-Werror]

If PLAT_RO_XLAT_TABLES is defined, the base xlat table goes to the
.rodata section instead of .bss section.
This causes a warning like:
/tmp/ccswitLr.s: Assembler messages:
/tmp/ccswitLr.s:297: Warning: setting incorrect section attributes for .rodata
It is practically no problem, but I want to keep the build log clean.
Put the base table into the "base_xlat_table" section to suppress the
assembler warnings.
The linker script determines its final destination; rodata section if
PLAT_RO_XLAT_TABLES=1, or bss section otherwise. So, the result is the
same.

Move the bss section to the common header. This adds BAKERY_LOCK_NORMAL
and PMF_TIMESTAMP, which previously existed only in BL31. This is not
a big deal because unused data should not be compiled in the first
place. I believe this should be controlled by BL*_SOURCES in Makefiles,
not by linker scripts.
I investigated BL1, BL2, BL2U, BL31 for plat=fvp, and BL2-AT-EL3,
BL31, BL31 for plat=uniphier. I did not see any more unexpected
code addition.
The bss section has bigger alignment. I added BSS_ALIGN for this.
Currently, SORT_BY_ALIGNMENT() is missing in sp_min.ld.S, and with this
change, the BSS symbols in SP_MIN will be sorted by the alignment.
This is not a big deal (or, even better in terms of the image size).

The common section data are repeated in many linker scripts (often
twice in each script to support SEPARATE_CODE_AND_RODATA). When you
add a new read-only data section, you end up with touching lots of
places.
After this commit, you will only need to touch bl_common.ld.h when
you add a new section to RODATA_COMMON.
Replace a series of RO section with RODATA_COMMON, which contains
6 sections, some of which did not exist before.
This is not a big deal because unneeded data should not be compiled
in the first place. I believe this should be controlled by BL*_SOURCES
in Makefiles, not by linker scripts.
When I was working on this commit, the BL1 image size increased
due to the fconf_populator. Commit c452ba159c ("fconf: exclude
fconf_dyn_cfg_getter.c from BL1_SOURCES") fixed this issue.
I investigated BL1, BL2, BL2U, BL31 for plat=fvp, and BL2-AT-EL3,

These are mostly used to collect data from special structure,
and repeated in many linker scripts.
To differentiate the alignment size between aarch32/aarch64, I added
a new macro STRUCT_ALIGN.
While I moved the PMF_SVC_DESCS, I dropped #if ENABLE_PMF conditional.
As you can see in include/lib/pmf/pmf_helpers.h, PMF_REGISTER_SERVICE*
are no-op when ENABLE_PMF=0. So, pmf_svc_descs and pmf_timestamp_array
data are not populated.

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".

[Andre: adapt to unified plat_helpers.S, smaller fixes]
Signed-off-by: Andre Przywara <andre.przywara@arm.com>
When writing to arbitrary locations in memory using a constructed
pointer, there is no guarantee that the compiler does not optimise away
the access, since it cannot detect any dependency.
One typical solution is to use the "volatile" keyword, but using MMIO
accessors in usually the better answer, to avoid torn writes.
Replace the usage of an array with such an MMIO accessor function in
rpi3_pwr_domain_on(), to make sure the write is really happening.

The plat_helpers.S file was almost identical between its RPi3 and RPi4
versions. Unify the two files, moving it into the common/ directory.
This adds a plat_rpi_get_model() function, which can be used to trigger
RPi4 specific action, detected at runtime. We use that to do the RPi4
specific L2 cache initialisation.

BL2 for this platform uses mmap_add_dynamic_region(), but BL31 and

At the moment, OP-TEE has no support to receive a DTB in Secure Memory
so it cannot receive TOS_FW_CONFIG_ID as it is supposed to happen on
any BL32 image. Instead, when OP-TEE is enable as BL32 payload,
NT_FW_CONFIG_ID is passed.
This MUST be reverted as soon as OP-TEE has support for receiving
DTBs from Secure Memory.
