2017-04-06zynqmp: Enable workaround for errata 855873Soren Brinkmann
Zynqmp implements a version of the Cortex A53 affected by errata 855873. Enable the workaround for the errata and silence the warning: "WARNING: BL31: cortex_a53: errata workaround for 855873 was missing!". Signed-off-by: Soren Brinkmann <soren.brinkmann@xilinx.com>
2017-03-20Move plat/common source file definitions to generic Makefilesdp-arm
These source file definitions should be defined in generic Makefiles so that all platforms can benefit. Ensure that the symbols are properly marked as weak so they can be overridden by platforms. NOTE: This change is a potential compatibility break for non-upstream platforms. Change-Id: I7b892efa9f2d6d216931360dc6c436e1d10cffed Signed-off-by: dp-arm <dimitris.papastamos@arm.com>
2017-02-06Replace some memset call by zeromemDouglas Raillard
Replace all use of memset by zeromem when zeroing moderately-sized structure by applying the following transformation: memset(x, 0, sizeof(x)) => zeromem(x, sizeof(x)) As the Trusted Firmware is compiled with -ffreestanding, it forbids the compiler from using __builtin_memset and forces it to generate calls to the slow memset implementation. Zeromem is a near drop in replacement for this use case, with a more efficient implementation on both AArch32 and AArch64.

2017-01-18Move BL_COHERENT_RAM_BASE/END defines to common_def.hMasahiro Yamada
We have lots of duplicated defines (and comment blocks too). Move them to include/plat/common/common_def.h. While we are here, suffix the end address with _END instead of _LIMIT. The _END is a better fit to indicate the linker-derived real end address. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-01-18Use *_END instead of *_LIMIT for linker derived end addressesMasahiro Yamada
The usage of _LIMIT seems odd here, so rename as follows: BL_CODE_LIMIT --> BL_CODE_END BL_RO_DATA_LIMIT --> BL_RO_DATA_END BL1_CODE_LIMIT --> BL1_CODE_END BL1_RO_DATA_LIMIT --> BL1_RO_DATA_END Basically, we want to use _LIMIT and _END properly as follows: *_SIZE + *_MAX_SIZE = *_LIMIT *_SIZE + *_SIZE = *_END The _LIMIT is generally defined by platform_def.h to indicate the platform-dependent memory constraint. So, its typical usage is ASSERT(. <= BL31_LIMIT, "BL31 image has exceeded its limit.") in a linker script. On the other hand, _END is used to indicate the end address of the compiled image, i.e. we do not know it until the image is linked. Here, all of these macros belong to the latter, so should be suffixed with _END. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2016-12-21zynqmp: add "override" directive to mandatory optionsMasahiro Yamada
The platform.mk sets build options required for ZynqMP, but users can still change them from the command line, like: make PLAT=zynqmp RESET_TO_BL31=0 CROSS_COMPILE=... Then, the makefile shows an error message in that case: Using BL31 as the reset vector is only one option supported on ZynqMP. Please set RESET_TO_BL31 to 1. If the option is not user-configurable, the makefile can specify "override" to prevent users from changing it. We do not need the error message for the case that never happens. Likewise, ENABLE_PLAT_COMPAT := 0 and PROGRAMMABLE_RESET_ADDRESS := 1 are mandatory to avoid build error.

2016-12-05Define and use no_ret macro where no return is expectedJeenu Viswambharan
There are many instances in ARM Trusted Firmware where control is transferred to functions from which return isn't expected. Such jumps are made using 'bl' instruction to provide the callee with the location from which it was jumped to. Additionally, debuggers infer the caller by examining where 'lr' register points to. If a 'bl' of the nature described above falls at the end of an assembly function, 'lr' will be left pointing to a location outside of the function range. This misleads the debugger back trace. This patch defines a 'no_ret' macro to be used when jumping to functions from which return isn't expected. The macro ensures to use 'bl' instruction for the jump, and also, for debug builds, places a 'nop' instruction immediately thereafter (unless instructed otherwise) so as to leave 'lr' pointing within the function range.

During system suspend, identify slaves which are configured as wake sources and call pm_set_wakeup_source API for each of them. Identifying if device may wake the system is done by checking if any interrupt of that device is enabled in GICD_ISENABLER when the APU is about to enter SUSPEND_TO_RAM state. If such interrupt is found, pm_set_wakeup_source is called with corresponding PM node ID as argument. Signed-off-by: Filip Drazic <filip.drazic@aggios.com>

2016-07-08ARM platforms: Add support for SEPARATE_CODE_AND_RODATASandrine Bailleux
The arm_setup_page_tables() function used to expect a single set of addresses defining the extents of the whole read-only section, code and read-only data mixed up, which was mapped as executable. This patch changes this behaviour. arm_setup_page_tables() now expects 2 separate sets of addresses: - the extents of the code section; - the extents of the read-only data section. The code is mapped as executable, whereas the data is mapped as execute-never. New #defines have been introduced to identify the extents of the code and the read-only data section. Given that all BL images except BL1 share the same memory layout and linker script structure, these #defines are common across these images. The slight memory layout differences in BL1 have been handled by providing values specific to BL1. Note that this patch also affects the Xilinx platform port, which uses the arm_setup_page_tables() function. It has been updated accordingly, such that the memory mappings on this platform are unchanged. This is achieved by passing null values as the extents of the read-only data section so that it is ignored. As a result, the whole read-only section is still mapped as executable.

2016-07-08Introduce utils.h header fileSandrine Bailleux
This patch introduces a new header file: include/lib/utils.h. Its purpose is to provide generic macros and helper functions that are independent of any BL image, architecture, platform and even not specific to Trusted Firmware. For now, it contains only 2 macros: ARRAY_SIZE() and IS_POWER_OF_TWO(). These were previously defined in bl_common.h and xlat_tables.c respectively. bl_common.h includes utils.h to retain compatibility for platforms that relied on bl_common.h for the ARRAY_SIZE() macro. Upstream platform ports that use this macro have been updated to include utils.h. Change-Id: I960450f54134f25d1710bfbdc4184f12c049a9a9
2016-07-08Introduce arm_setup_page_tables() functionSandrine Bailleux
This patch introduces the arm_setup_page_tables() function to set up page tables on ARM platforms. It replaces the arm_configure_mmu_elx() functions and does the same thing except that it doesn't enable the MMU at the end. The idea is to reduce the amount of per-EL code that is generated by the C preprocessor by splitting the memory regions definitions and page tables creation (which is generic) from the MMU enablement (which is the only per-EL configuration). As a consequence, the call to the enable_mmu_elx() function has been moved up into the plat_arch_setup() hook. Any other ARM standard platforms that use the functions `arm_configure_mmu_elx()` must be updated. Change-Id: I6f12a20ce4e5187b3849a8574aac841a136de83d
