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

2015-12-14Replace all SCP FW (BL0, BL3-0) referencesJuan Castillo
This patch replaces all references to the SCP Firmware (BL0, BL30, BL3-0, bl30) with the image terminology detailed in the TF wiki (https://github.com/ARM-software/arm-trusted-firmware/wiki): BL0 --> SCP_BL1 BL30, BL3-0 --> SCP_BL2 bl30 --> scp_bl2 This change affects code, documentation, build system, tools and platform ports that load SCP firmware. ARM plaforms have been updated to the new porting API. IMPORTANT: build option to specify the SCP FW image has changed: BL30 --> SCP_BL2 IMPORTANT: This patch breaks compatibility for platforms that use BL2 to load SCP firmware. Affected platforms must be updated as follows: BL30_IMAGE_ID --> SCP_BL2_IMAGE_ID BL30_BASE --> SCP_BL2_BASE bl2_plat_get_bl30_meminfo() --> bl2_plat_get_scp_bl2_meminfo() bl2_plat_handle_bl30() --> bl2_plat_handle_scp_bl2() Change-Id: I24c4c1a4f0e4b9f17c9e4929da815c4069549e58
2015-12-14TBB: apply TBBR naming convention to certificates and extensionsJuan Castillo
This patch applies the TBBR naming convention to the certificates and the corresponding extensions defined by the CoT: * Certificate UUID names * Certificate identifier names * OID names Changes apply to: * Generic code (variables and defines) * The default certificate identifiers provided in the generic code * Build system * ARM platforms port * cert_create tool internal definitions * fip_create and cert_create tools command line options * Documentation IMPORTANT: this change breaks the compatibility with platforms that use TBBR. The platform will need to adapt the identifiers and OIDs to the TBBR naming convention introduced by this patch: Certificate UUIDs: UUID_TRUSTED_BOOT_FIRMWARE_BL2_CERT --> UUID_TRUSTED_BOOT_FW_CERT UUID_SCP_FIRMWARE_BL30_KEY_CERT --> UUID_SCP_FW_KEY_CERT UUID_SCP_FIRMWARE_BL30_CERT --> UUID_SCP_FW_CONTENT_CERT UUID_EL3_RUNTIME_FIRMWARE_BL31_KEY_CERT --> UUID_SOC_FW_KEY_CERT UUID_EL3_RUNTIME_FIRMWARE_BL31_CERT --> UUID_SOC_FW_CONTENT_CERT UUID_SECURE_PAYLOAD_BL32_KEY_CERT --> UUID_TRUSTED_OS_FW_KEY_CERT UUID_SECURE_PAYLOAD_BL32_CERT --> UUID_TRUSTED_OS_FW_CONTENT_CERT UUID_NON_TRUSTED_FIRMWARE_BL33_KEY_CERT --> UUID_NON_TRUSTED_FW_KEY_CERT UUID_NON_TRUSTED_FIRMWARE_BL33_CERT --> UUID_NON_TRUSTED_FW_CONTENT_CERT Certificate identifiers: BL2_CERT_ID --> TRUSTED_BOOT_FW_CERT_ID BL30_KEY_CERT_ID --> SCP_FW_KEY_CERT_ID BL30_CERT_ID --> SCP_FW_CONTENT_CERT_ID BL31_KEY_CERT_ID --> SOC_FW_KEY_CERT_ID BL31_CERT_ID --> SOC_FW_CONTENT_CERT_ID BL32_KEY_CERT_ID --> TRUSTED_OS_FW_KEY_CERT_ID BL32_CERT_ID --> TRUSTED_OS_FW_CONTENT_CERT_ID BL33_KEY_CERT_ID --> NON_TRUSTED_FW_KEY_CERT_ID BL33_CERT_ID --> NON_TRUSTED_FW_CONTENT_CERT_ID OIDs: TZ_FW_NVCOUNTER_OID --> TRUSTED_FW_NVCOUNTER_OID NTZ_FW_NVCOUNTER_OID --> NON_TRUSTED_FW_NVCOUNTER_OID BL2_HASH_OID --> TRUSTED_BOOT_FW_HASH_OID TZ_WORLD_PK_OID --> TRUSTED_WORLD_PK_OID NTZ_WORLD_PK_OID --> NON_TRUSTED_WORLD_PK_OID BL30_CONTENT_CERT_PK_OID --> SCP_FW_CONTENT_CERT_PK_OID BL30_HASH_OID --> SCP_FW_HASH_OID BL31_CONTENT_CERT_PK_OID --> SOC_FW_CONTENT_CERT_PK_OID BL31_HASH_OID --> SOC_AP_FW_HASH_OID BL32_CONTENT_CERT_PK_OID --> TRUSTED_OS_FW_CONTENT_CERT_PK_OID BL32_HASH_OID --> TRUSTED_OS_FW_HASH_OID BL33_CONTENT_CERT_PK_OID --> NON_TRUSTED_FW_CONTENT_CERT_PK_OID BL33_HASH_OID --> NON_TRUSTED_WORLD_BOOTLOADER_HASH_OID BL2U_HASH_OID --> AP_FWU_CFG_HASH_OID SCP_BL2U_HASH_OID --> SCP_FWU_CFG_HASH_OID NS_BL2U_HASH_OID --> FWU_HASH_OID Change-Id: I1e047ae046299ca913911c39ac3a6e123bd41079
2015-12-09FWU: Add Firmware Update support in BL1 for ARM platformsYatharth Kochar
This patch adds Firmware Update support for ARM platforms. New files arm_bl1_fwu.c and juno_bl1_setup.c were added to provide platform specific Firmware update code. BL1 now includes mmap entry for `ARM_MAP_NS_DRAM1` to map DRAM for authenticating NS_BL2U image(For both FVP and JUNO platform). Change-Id: Ie116cd83f5dc00aa53d904c2f1beb23d58926555
2015-11-02Remove deprecated IO return definitionsJuan Castillo
Patch 7e26fe1f deprecates IO specific return definitions in favour of standard errno codes. This patch removes those definitions and its usage from the IO framework, IO drivers and IO platform layer. Following this patch, standard errno codes must be used when checking the return value of an IO function. Change-Id: Id6e0e9d0a7daf15a81ec598cf74de83d5768650f
2015-06-25Use numbers to identify images instead of namesJuan Castillo
The Trusted firmware code identifies BL images by name. The platform port defines a name for each image e.g. the IO framework uses this mechanism in the platform function plat_get_image_source(). For a given image name, it returns the handle to the image file which involves comparing images names. In addition, if the image is packaged in a FIP, a name comparison is required to find the UUID for the image. This method is not optimal. This patch changes the interface between the generic and platform code with regard to identifying images. The platform port must now allocate a unique number (ID) for every image. The generic code will use the image ID instead of the name to access its attributes. As a result, the plat_get_image_source() function now takes an image ID as an input parameter. The organisation of data structures within the IO framework has been rationalised to use an image ID as an index into an array which contains attributes of the image such as UUID and name. This prevents the name comparisons. A new type 'io_uuid_spec_t' has been introduced in the IO framework to specify images identified by UUID (i.e. when the image is contained in a FIP file). There is no longer need to maintain a look-up table [iname_name --> uuid] in the io_fip driver code. Because image names are no longer mandatory in the platform port, the debug messages in the generic code will show the image identifier instead of the file name. The platforms that support semihosting to load images (i.e. FVP) must provide the file names as definitions private to the platform. The ARM platform ports and documentation have been updated accordingly. All ARM platforms reuse the image IDs defined in the platform common code. These IDs will be used to access other attributes of an image in subsequent patches. IMPORTANT: applying this patch breaks compatibility for platforms that use TF BL1 or BL2 images or the image loading code. The platform port must be updated to match the new interface.

2015-04-28Add common ARM and CSS platform codeDan Handley
This major change pulls out the common functionality from the FVP and Juno platform ports into the following categories: * (include/)plat/common. Common platform porting functionality that typically may be used by all platforms. * (include/)plat/arm/common. Common platform porting functionality that may be used by all ARM standard platforms. This includes all ARM development platforms like FVP and Juno but may also include non-ARM-owned platforms. * (include/)plat/arm/board/common. Common platform porting functionality for ARM development platforms at the board (off SoC) level. * (include/)plat/arm/css/common. Common platform porting functionality at the ARM Compute SubSystem (CSS) level. Juno is an example of a CSS-based platform. * (include/)plat/arm/soc/common. Common platform porting functionality at the ARM SoC level, which is not already defined at the ARM CSS level. No guarantees are made about the backward compatibility of functionality provided in (include/)plat/arm. Also remove any unnecessary variation between the ARM development platform ports, including: * Unify the way BL2 passes `bl31_params_t` to BL3-1. Use the Juno implementation, which copies the information from BL2 memory instead of expecting it to persist in shared memory. * Unify the TZC configuration. There is no need to add a region for SCP in Juno; it's enough to simply not allow any access to this reserved region. Also set region 0 to provide no access by default instead of assuming this is the case. * Unify the number of memory map regions required for ARM development platforms, although the actual ranges mapped for each platform may be different. For the FVP port, this reduces the mapped peripheral address space. These latter changes will only be observed when the platform ports are migrated to use the new common platform code in subsequent patches. Change-Id: Id9c269dd3dc6e74533d0e5116fdd826d53946dc8
