      TF-A GICv3 driver: Introduce makefile · a6ea06f5
      Alexei Fedorov authored 
      

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.

      Enable -Wredundant-decls warning check · ca661a00
      Madhukar Pappireddy authored 
      

This flag warns if anything is declared more than once in the same
scope, even in cases where multiple declaration is valid and changes
nothing.

Consequently, this patch also fixes the issues reported by this
flag. Consider the following two lines of code from two different source
files(bl_common.h and bl31_plat_setup.c):

IMPORT_SYM(uintptr_t, __RO_START__, BL_CODE_BASE);
IMPORT_SYM(unsigned long, __RO_START__, BL2_RO_BASE);

The IMPORT_SYM macro which actually imports a linker symbol as a C expression.
The macro defines the __RO_START__ as an extern variable twice, one for each
instance. __RO_START__ symbol is defined by the linker script to mark the start
of the Read-Only area of the memory map.

Essentially, the platform code redefines the linker symbol with a different
(relevant) name rather than using the standard symbol. A simple solution to
fix this issue in the platform code for redundant declarations warning is
to remove the second IMPORT_SYM and replace it with following assignment

static const unsigned long BL2_RO_BASE = BL_CODE_BASE;

      Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__ · d5dfdeb6
      Julius Werner authored 
      

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

      Mbed TLS: Remove weak heap implementation · 2374ab17
      Ambroise Vincent authored 
      

The implementation of the heap function plat_get_mbedtls_heap() becomes
mandatory for platforms supporting TRUSTED_BOARD_BOOT.

The shared Mbed TLS heap default weak function implementation is
converted to a helper function get_mbedtls_heap_helper() which can be
used by the platforms for their own function implementation.

      plat: imx8m: Add the basic support for imx8mm · 179f82a2
      Jacky Bai authored 
      

The i.MX8M Mini is new SOC of the i.MX8M family. it is
focused on delivering the latest and greatest video and
audio experience combining state-of-the-art media-specific
features with high-performance processing while optimized
for lowest power consumption. The i.MX 8M Mini Media Applications
Processor is  14nm FinFET product of the growing i.MX8M family
targeting the consumer & industrial market. It is built in 14LPP
to achieve both high performance and low power consumption
and relies on a powerful fully coherent core complex based on
a quad Cortex-A53 cluster with video and graphics accelerators

this patch add the basic support for i.MX8MM.

      imx: make sure GIC redistributor is awake before initialization · e655fefc
      Anson Huang authored 
      

GICR_WAKER.ProcessorSleep can only be set to zero when:
— GICR_WAKER.Sleep bit[0] == 0.
— GICR_WAKER.Quiescent bit[31] == 0.

On some platforms, when system reboot with GIC in sleep
mode but with power ON, such as on NXP's i.MX8QM, Linux
kernel enters suspend but could be requested to reboot,
and GIC is in sleep mode and it is inside a power domain
which is ON in this scenario, when CPU reset, the GIC
driver trys to set CORE's redistributor interface to awake,
with GICR_WAKER.Sleep bit[0] and GICR_WAKER.Quiescent bit[31]
both set, the ProcessorSleep bit[1] will never be clear
and cause system hang.

This patch makes sure GICR_WAKER.Sleep bit[0] and
GICR_WAKER.Quiescent bit[31] are both zeor before clearing
ProcessorSleep bit[1].
