GICv3: Enable multi socket GIC redistributor frame discovery

2019-09-26T03:01:28Z

This patch provides declaration and definition of new GICv3 driver API: gicv3_rdistif_probe().This function delegates the responsibility of discovering the corresponding Redistributor base frame to each CPU itself. It is a modified version of gicv3_rdistif_base_addrs_probe() and is executed by each CPU in the platform unlike the previous approach in which only the Primary CPU did the discovery of all the Redistributor frames for every CPU. The flush operations as part of gicv3_driver_init() function are made necessary even for platforms with WARMBOOT_ENABLE_DCACHE_EARLY because the GICv3 driver data structure contents are accessed by CPU with D-Cache turned off during power down operations.

Replace ASSEMBLY with compiler-builtin ASSEMBLER

2019-08-01T20:14:12Z

NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__. All common C compilers predefine a macro called __ASSEMBLER__ when preprocessing a .S file. There is no reason for TF-A to define it's own __ASSEMBLY__ macro for this purpose instead. To unify code with the export headers (which use __ASSEMBLER__ to avoid one extra dependency), let's deprecate __ASSEMBLY__ and switch the code base over to the predefined standard.

cryptocell: add product version awareness support

2019-07-25T10:38:07Z

Add support for multiple Cryptocell revisions which use different APIs. This commit only refactors the existing code in preperation to the addition of another Cryptocell revisions later on. Signed-off-by: Gilad Ben-Yossef Change-Id: I16d80b31afb6edd56dc645fee5ea619cc74f09b6

cryptocell: move Cryptocell specific API into driver

2019-07-25T10:29:15Z

Code using Cryptocell specific APIs was used as part of the arm common board ROT support, instead of being abstracted in Cryptocell specific driver code, creating two problems: - Any none arm board that uses Cryptocell wuld need to copy and paste the same code. - Inability to cleanly support multiple versions of Cryptocell API and products. Move over Cryptocell specific API calls into the Cryptocell driver, creating abstraction API where needed. Signed-off-by: Gilad Ben-Yossef Change-Id: I9e03ddce90fcc47cfdc747098bece86dbd11c58e

SMMUv3: Abort DMA transactions

2019-05-10T15:09:19Z

For security DMA should be blocked at the SMMU by default unless explicitly enabled for a device. SMMU is disabled after reset with all streams bypassing the SMMU, and abortion of all incoming transactions implements a default deny policy on reset. This patch also moves "bl1_platform_setup()" function from arm_bl1_setup.c to FVP platforms' fvp_bl1_setup.c and fvp_ve_bl1_setup.c files.

SMMUv3: refactor the driver code

2019-05-03T09:27:46Z

This patch is a preparation for the subsequent changes in SMMUv3 driver. It introduces a new "smmuv3_poll" function and replaces inline functions for accessing SMMU registers with mmio read/write operations. Also the infinite loop for the poll has been replaced with a counter based timeout. Change-Id: I7a0547beb1509601f253e126b1a7a6ab3b0307e7 Signed-off-by: Alexei Fedorov

drivers/sbsa: add sbsa watchdog driver

Add a driver for configuring the SBSA Generic Watchdog which aids in the detection of errant system behaviour. Change-Id: I5a1e7149c69fd8b85be7dfbcf511f431339946f4 Signed-off-by: Aditya Angadi

tzc: remove deprecated types

Remove several warnings reported with W=1

2019-04-01T09:43:42Z

Improved support for W=1 compilation flag by solving missing-prototypes and old-style-definition warnings. The libraries are compiling with warnings (which turn into errors with the Werror flag). Outside of libraries, some warnings cannot be fixed without heavy structural changes. Change-Id: I1668cf99123ac4195c2a6a1d48945f7a64c67f16 Signed-off-by: Ambroise Vincent

plat/arm: mhu: make mhu driver generic

2019-03-13T00:54:35Z

MHU doorbell driver requires arm platform specific macro "PLAT_CSS_MHU_BASE". Rename it to "PLAT_MHUV2_BASE", so that platforms other than arm can use generic MHU doorbell driver. Signed-off-by: Masahisa Kojima
