Report errata workaround status to console The errata reporting policy is as follows: - If an errata workaround is enabled: - If it applies (i.e. the CPU is affected by the errata), an INFO message is printed, confirming that the errata workaround has been applied. - If it does not apply, a VERBOSE message is printed, confirming that the errata workaround has been skipped. - If an errata workaround is not enabled, but would have applied had it been, a WARN message is printed, alerting that errata workaround is missing. The CPU errata messages are printed by both BL1 (primary CPU only) and runtime firmware on debug builds, once for each CPU/errata combination. Relevant output from Juno r1 console when ARM Trusted Firmware is built with PLAT=juno LOG_LEVEL=50 DEBUG=1: VERBOSE: BL1: cortex_a57: errata workaround for 806969 was not applied VERBOSE: BL1: cortex_a57: errata workaround for 813420 was not applied INFO: BL1: cortex_a57: errata workaround for disable_ldnp_overread was applied WARNING: BL1: cortex_a57: errata workaround for 826974 was missing!

Remove vpath usage in makefiles Remove all usage of the vpath keyword in makefiles as it was prone to mistakes. Specify the relative paths to source files instead. Also reorder source files in makefiles alphabetically. Fixes ARM-software/tf-issues#121 Change-Id: Id15f60655444bae60e0e2165259efac71a50928b

AArch32: Add generic changes in BL1 This patch adds generic changes in BL1 to support AArch32 state. New AArch32 specific assembly/C files are introduced and some files are moved to AArch32/64 specific folders. BL1 for AArch64 is refactored but functionally identical. BL1 executes in Secure Monitor mode in AArch32 state. NOTE: BL1 in AArch32 state ONLY handles BL1_RUN_IMAGE SMC. Change-Id: I6e2296374c7efbf3cf2aa1a0ce8de0732d8c98a5

Move plat/common source file definitions to generic Makefiles 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.

bl2-el3: Don't compile BL1 when BL2_AT_EL3 is defined in FVP This patch modifies the makefiles to avoid the definition of BL1_SOURCES and BL2_SOURCES in the tbbr makefiles, and it lets to the platform makefiles to define them if they actually need these images. In the case of BL2_AT_EL3 BL1 will not be needed usually because the Boot ROM will jump directly to BL2.

FWU: Add Generic Firmware Update framework support in BL1 Firmware update(a.k.a FWU) feature is part of the TBB architecture. BL1 is responsible for carrying out the FWU process if platform specific code detects that it is needed. This patch adds support for FWU feature support in BL1 which is included by enabling `TRUSTED_BOARD_BOOT` compile time flag. This patch adds bl1_fwu.c which contains all the core operations of FWU, which are; SMC handler, image copy, authentication, execution and resumption. It also adds bl1.h introducing #defines for all BL1 SMCs. Following platform porting functions are introduced: int bl1_plat_mem_check(uintptr_t mem_base, unsigned int mem_size, unsigned int flags); This function can be used to add platform specific memory checks for the provided base/size for the given security state. The weak definition will invoke `assert()` and return -ENOMEM. __dead2 void bl1_plat_fwu_done(void *cookie, void *reserved); This function can be used to initiate platform specific procedure to mark completion of the FWU process. The weak definition waits forever calling `wfi()`. plat_bl1_common.c contains weak definitions for above functions. FWU process starts when platform detects it and return the image_id other than BL2_IMAGE_ID by using `bl1_plat_get_next_image_id()` in `bl1_main()`. NOTE: User MUST provide platform specific real definition for bl1_plat_mem_check() in order to use it for Firmware update. Change-Id: Ice189a0885d9722d9e1dd03f76cac1aceb0e25ed
