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.

Unless specified in the environment, $(CC) expands to some generic
host C compiler like cc or c99. We set our own value for $(CC), but
only few lines later.

Move the first use of the $(CC) variable behind the definition to
correct this.

fconf_dyn_cfg_getter.c calls FCONF_REGISTER_POPULATOR(), which populates
the fconf_populator structure.

However, bl1/bl1.ld.S does not have:

        __FCONF_POPULATOR_START__ = .;
        KEEP(*(.fconf_populator))
        __FCONF_POPULATOR_END__ = .;

So, this is not linked to bl1.elf

We could change either bl1/bl1.lds.S or lib/fconf/fconf.mk to make
them consistent.

I chose to fix up fconf.mk to keep the current behavior.

This is a groundwork to factor out the common code from linker scripts.

sp_min.ld.S is used for aarch32.

ALIGN(4) is used for alignment of the other structures. I do not think
struct fconf_populator is a special case. Let's use ALIGN(4) here too.

Perhaps, this is just a copy-paste mistake of commit 26d1e0c3


("fconf: necessary modifications to support fconf in BL31 & SP_MIN").

-D is a preprocessor flag that defines a macro. So, adding it to
BL*_CPPFLAGS makes more sense. You can reference it not only from
.c files but also from .S files.

Currently, BL*_CFLAGS and BL*_LDFLAGS are supported.

For completion, this adds BL*_CPPFLAGS and BL*_ASFLAGS.

My main motivation is to pass -D<macro> to BL*_CPPFLAGS so that
the macro can be used from all source files.

enable_mmu_* has a different function name, so it is not handy in the
shared code. enable_mmu() calls an appropriate one depending on the
exception level.

There are some cases where we want to run EL-dependent code in the
shared code.

We could use #ifdef, but it leaves slight possibility where we do not
know the exception level at the build-time (e.g. library code).

The counter approach is to use get_current_el(), but it is run-time
detection, so all EL code is linked, some of which might be unneeded.

This commit adds get_current_el_maybe_constant(). This is a static
inline function that returns a constant value if we know the exception
level at build-time. This is mostly the case.

    if (get_current_el_maybe_constant() == 1) {
            /* do something for EL1 */
    } else if (get_current_el_maybe_constant() == 3) {
            /* do something for EL3 */
    }

If get_current_el_maybe_constant() is build-time constant, the compiler
will optimize out the unreachable code.

If such code is included from the library code, it is not built-time
constant. In this case, it falls back to get_current_el(), so it still
works.

The build system defines the IMAGE_BL* macro when compiling each image.
This is useful to distinguish which image the current file is being
built for by using #if defined(IMAGE_BL2) or #if defined(IMAGE_BL31),
or whatever.

There are some cases where we are more interested in which exception
level the current file is being built for.

include/lib/cpus/{aarch32,aarch64}/cpu_macros.S defines IMAGE_AT_EL3,
but we do not have it globally.

Pass IMAGE_AT_EL1 or IMAGE_AT_EL3 to BL*_CFLAGS so that it is available
from all C code.

The library code (libc.a, libmbedtls.a, etc.) is exceptional cases,
where the code can be shared between BL images.

Other than that, we know the exception level at the build time, and
this macro will be useful in the shared code.

This patch moves all GICv3 driver files into new added
'gicv3.mk' makefile for the benefit of the generic driver
which can evolve in the future without affecting platforms.
The patch adds GICv3 driver configuration flags
'GICV3_IMPL', 'GICV3_IMPL_GIC600_MULTICHIP' and
'GICV3_OVERRIDE_DISTIF_PWR_OPS' described in
'GICv3 driver options' section of 'build-option.rst'
document.

NOTE: Platforms with GICv3 driver need to be modified to
include 'drivers/arm/gic/v3/gicv3.mk' in their makefiles.

On DynamIQ CPU FVPs, stats test cases are failing when
hardware-assisted coherency is enabled due to a corrupt
timestamp value. Investigation of the issue indicates that
on these models the timestamp value is stored in cache
instead of memory. This patch flushes the dcache when the
timestamp is stored to make sure it is stored in memory.
