2020-10-09Don't return error information from console_flushJimmy Brisson
And from crash_console_flush. We ignore the error information return by console_flush in _every_ place where we call it, and casting the return type to void does not work around the MISRA violation that this causes. Instead, we collect the error information from the driver (to avoid changing that API), and don't return it to the caller.

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.

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.

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.

2020-03-05imx: console: Use CONSOLE_T_BASE for UART base addressAndre Przywara
Since commit ac71344e9eca we have the UART base address in the generic console_t structure. For most platforms the platform-specific struct console is gone, so we *must* use the embedded base address, since there is no storage behind the generic console_t anymore. Replace the usage of CONSOLE_T_DRVDATA with CONSOLE_T_BASE to fix this.

2020-01-28Enable -Wredundant-decls warning checkMadhukar Pappireddy
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; Change-Id: If4835d1ee462d52b75e5afd2a59b64828707c5aa Signed-off-by: Madhukar Pappireddy <madhukar.pappireddy@arm.com>

2019-08-01Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__Julius Werner
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.

Work around this by parsing the ROM header and checking if OCOTP register 0x40 is stuck at 0xff0055aa. Determining this inside TF-A makes life easier for OS, see for example this linux discussion: https://lkml.org/lkml/2019/5/3/465 The soc revision can also be useful inside TF-A itself, for example for the non-upstream DDR DVFS "busfreq" feature is affected by 8mq erratas. The clock for OCOTP block can be disabled by OS so only initialize soc revision once at boot time.
