2014-10-29	b1a9631 Browse files » Optimize barrier usage during Cortex-A57 power down ... This the patch replaces the DSB SY with DSB ISH after disabling L2 prefetches during the Cortex-A57 power down sequence.

	7395a72 Browse files » Apply errata workarounds only when major/minor revisions match. ... Prior to this patch, the errata workarounds were applied for any version of the CPU in the release build and in the debug build an assert failure resulted when the revision did not match. This patch applies errata workarounds in the Cortex-A57 reset handler only if the 'variant' and 'revision' fields read from the MIDR_EL1 match. In the debug build, a warning message is printed for each errata workaround which is not applied. The patch modifies the register usage in 'reset_handler` so as to adhere to ARM procedure calling standards.

	8e85791 Browse files » Add support for level specific cache maintenance operations ... This patch adds level specific cache maintenance functions to cache_helpers.S. The new functions 'dcsw_op_levelx', where '1 <= x <= 3', allow to perform cache maintenance by set/way for that particular level of cache. With this patch, functions to support cache maintenance upto level 3 have been implemented since it is the highest cache level for most ARM SoCs. These functions are now utilized in CPU specific power down sequences to implement them as mandated by processor specific technical reference manual.

2014-10-22	20d51ca Browse files » FVP: keep shared data in Trusted SRAM ... This patch deprecates the build option to relocate the shared data into Trusted DRAM in FVP. After this change, shared data is always located at the base of Trusted SRAM. This reduces the complexity of the memory map and the number of combinations in the build options.

2014-10-14	740134e Browse files » Juno: Reserve some DDR-DRAM for secure use ... This patch configures the TrustZone Controller in Juno to split the 2GB DDR-DRAM memory at 0x80000000 into Secure and Non-Secure regions: - Secure DDR-DRAM: top 16 MB, except for the last 2 MB which are used by the SCP for DDR retraining - Non-Secure DDR-DRAM: remaining DRAM starting at base address Build option PLAT_TSP_LOCATION selects the location of the secure payload (BL3-2): - 'tsram' : Trusted SRAM (default option) - 'dram' : Secure region in the DDR-DRAM (set by the TrustZone controller) The MMU memory map has been updated to give BL2 permission to load BL3-2 into the DDR-DRAM secure region.

2014-10-09	ef538c6 Browse files » Juno: Use TZC-400 driver calls ... This patch replaces direct accesses to the TZC-400 registers by the appropiate calls to the generic driver available in the Trusted Firmware in order to initialize the TrustZone Controller. Functions related to the initialization of the secure memory, like the TZC-400 configuration, have been moved to a new file 'plat_security.c'. This reorganization makes easier to set up the secure memory from any BL stage. TZC-400 initialization has been moved from BL1 to BL2 because BL1 does not access the non-secure memory. It is BL2's responsibility to enable and configure the TZC-400 before loading the next BL images. In Juno, BL3-0 initializes some of the platform peripherals, like the DDR controller. Thus, BL3-0 must be loaded before configuring the TrustZone Controller. As a consequence, the IO layer initialization has been moved to early platform initialization.

2014-09-25	d0ecd97 Browse files » Create BL stage specific translation tables ... This patch uses the IMAGE_BL<x> constants to create translation tables specific to a boot loader stage.

2014-09-22	6ab0391 Browse files » Remove BSS section access by 'plat_print_gic' during crash reporting ... This patch avoids the problem of crash reporting mechanism accessing global data in BSS by 'plat_print_gic_regs' for FVP platforms. Earlier it depended on the global 'plat_config' object for the GIC Base address in FVP platforms which would have caused exception if it were accessed before the BSS was initialized. It is now fixed by dynamically querying the V2M_SYS_ID to find the FVP model type and accordingly selecting the appropriate GIC Base address. This patch also fixes the 'plat_print_gic_regs' to use the correct GIC Distributor base address for printing GICD_IS_PENDR register values for both Juno and FVP platforms.

	27713fb Browse files » Add support for specifying pre-built BL binaries in Makefile ... This patch adds support for supplying pre-built BL binaries for BL2, BL3-1 and BL3-2 during trusted firmware build. Specifying BLx = <path_to_BLx> in the build command line, where 'x' is any one of BL2, BL3-1 or BL3-2, will skip building that BL stage from source and include the specified binary in final fip image. This patch also makes BL3-3 binary for FIP optional depending on the value of 'NEED_BL33' flag which is defined by the platform.
