      plat: imx8mp: Add the basic support for i.MX8MP · a775ef25
      Jacky Bai authored 
      

The i.MX 8MP Media Applications Processor is part of the growing
i.MX8M family targeting the consumer and industrial market. It brings
an effective Machine Learning and AI accelerator that enables a new
class of applications. 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 core Arm Cortex-A53 cluster and
Cortex-M7 low-power coprocessor, audio digital signal processor, machine
learning and graphics accelerators.

      plat: imx8m: Move the gpc hw reg to a separate header file · 9e5c3e92
      Jacky Bai authored 
      

Although the GPC provides the similar functions for all the
i.MX8M SoC family, the HW register offset and bit defines
still have some slight difference, so move the hw reg
offset & most of the bitfield defines in 'gpc_reg.h' that
is specific to each SoC.

      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.

      plat: imx: imx8qx: provide debug uart num as build param · 30617cca
      Igor Opaniuk authored 
      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 98a69dfd

("plat: imx: imx8qm: apply clk/pinmux
configuration for DEBUG_CONSOLE")).

Usage:
$ make PLAT=imx8qx IMX_DEBUG_UART=3 DEBUG_CONSOLE=1 bl31

      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.
