2017-06-20Resolve build errors flagged by GCC 6.2David Cunado
With GCC 6.2 compiler, more C undefined behaviour is being flagged as warnings, which result in build errors in ARM TF build. This patch addresses issue caused by enums with values that exceed maximum value for an int. For these cases the enum is converted to a set of defines.

2017-03-31Add support for GCC stack protectionDouglas Raillard
Introduce new build option ENABLE_STACK_PROTECTOR. It enables compilation of all BL images with one of the GCC -fstack-protector-* options. A new platform function plat_get_stack_protector_canary() is introduced. It returns a value that is used to initialize the canary for stack corruption detection. Returning a random value will prevent an attacker from predicting the value and greatly increase the effectiveness of the protection. A message is printed at the ERROR level when a stack corruption is detected. To be effective, the global data must be stored at an address lower than the base of the stacks. Failure to do so would allow an attacker to overwrite the canary as part of an attack which would void the protection. FVP implementation of plat_get_stack_protector_canary is weak as there is no real source of entropy on the FVP. It therefore relies on a timer's value, which could be predictable.

2017-03-31Add console_core_flush() in upstream platformsAntonio Nino Diaz
It is needed to add placeholders for this function because, as this is not a `plat_xxx()` function, there aren't weak definitions of it in any file. If `console_flush()` is used and there isn't an implementation of `console_core_flush()` in any file, the compilation will fail.

2017-02-06Introduce unified API to zero memoryDouglas Raillard
Introduce zeromem_dczva function on AArch64 that can handle unaligned addresses and make use of DC ZVA instruction to zero a whole block at a time. This zeroing takes place directly in the cache to speed it up without doing external memory access. Remove the zeromem16 function on AArch64 and replace it with an alias to zeromem. This zeromem16 function is now deprecated. Remove the 16-bytes alignment constraint on __BSS_START__ in firmware-design.md as it is now not mandatory anymore (it used to comply with zeromem16 requirements). Change the 16-bytes alignment constraints in SP min's linker script to a 8-bytes alignment constraint as the AArch32 zeromem implementation is now more efficient on 8-bytes aligned addresses. Introduce zero_normalmem and zeromem helpers in platform agnostic header that are implemented this way: * AArch32: * zero_normalmem: zero using usual data access * zeromem: alias for zero_normalmem * AArch64: * zero_normalmem: zero normal memory using DC ZVA instruction (needs MMU enabled) * zeromem: zero using usual data access Usage guidelines: in most cases, zero_normalmem should be preferred. There are 2 scenarios where zeromem (or memset) must be used instead: * Code that must run with MMU disabled (which means all memory is considered device memory for data accesses). * Code that fills device memory with null bytes. Optionally, the following rule can be applied if performance is important: * Code zeroing small areas (few bytes) that are not secrets should use memset to take advantage of compiler optimizations. Note: Code zeroing security-related critical information should use zero_normalmem/zeromem instead of memset to avoid removal by compilers' optimizations in some cases or misbehaving versions of GCC.

2017-01-24Use #ifdef for IMAGE_BL* instead of #ifMasahiro Yamada
One nasty part of ATF is some of boolean macros are always defined as 1 or 0, and the rest of them are only defined under certain conditions. For the former group, "#if FOO" or "#if !FOO" must be used because "#ifdef FOO" is always true. (Options passed by $(call add_define,) are the cases.) For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because checking the value of an undefined macro is strange. Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like follows: $(eval IMAGE := IMAGE_BL$(call uppercase,$(3))) $(OBJ): $(2) @echo " CC $$<" $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@ This means, IMAGE_BL* is defined when building the corresponding image, but *undefined* for the other images. So, IMAGE_BL* belongs to the latter group where we should use #ifdef or #ifndef. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

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

Disable PL011 UART before configuring it
2016-02-01Use tf_printf() for debug logs from xlat_tables.cSoby Mathew
The debug prints used to debug translation table setup in xlat_tables.c used the `printf()` standard library function instead of the stack optimized `tf_printf()` API. DEBUG_XLAT_TABLE option was used to enable debug logs within xlat_tables.c and it configured a much larger stack size for the platform in case it was enabled. This patch modifies these debug prints within xlat_tables.c to use tf_printf() and modifies the format specifiers to be compatible with tf_printf(). The debug prints are now enabled if the VERBOSE prints are enabled in Trusted Firmware via LOG_LEVEL build option. The much larger stack size definition when DEBUG_XLAT_TABLE is defined is no longer required and the platform ports are modified to remove this stack size definition.
