2019-09-25Migrate ARM platforms to use the new GICv3 APIMadhukar Pappireddy
This patch invokes the new function gicv3_rdistif_probe() in the ARM platform specific gicv3 driver. Since this API modifies the shared GIC related data structure, it must be invoked coherently by using the platform specific pwr_domain_on_finish_late hook.

2019-08-01Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__Julius Werner
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.

2019-04-17plat/arm: introduce wrapper functions to setup secure watchdogAditya Angadi
The BL1 stage setup code for ARM platforms sets up the SP805 watchdog controller as the secure watchdog. But not all ARM platforms use SP805 as the secure watchdog controller. So introduce two new ARM platform code specific wrapper functions to start and stop the secure watchdog. These functions then replace the calls to SP805 driver in common BL1 setup code. All the ARM platforms implement these wrapper functions by either calling into SP805 driver or the SBSA watchdog driver.

This file is used when building the cert_create tool without using the 'standard' set of Arm OID values as defined in the TBBR specification (see tbbr_oid.h). This configuration is enabled by setting USE_TBBR_DEFS to 0 during build. At the moment this will fail because the header file included by this file was removed in commit bb41eb7a9dc3 ("cert: move platform_oid.h to include/tools_share for all platforms"). For the SGM platform this means that there is no current use for this file. Change-Id: I3c82983ada62330f1ab6be6d6c0cf489adabae7b Signed-off-by: Paul Beesley <paul.beesley@arm.com>

Many parts of the code were duplicating symbols that are defined in include/common/bl_common.h. It is better to only use the definitions in this header. As all the symbols refer to virtual addresses, they have to be uintptr_t, not unsigned long. This has also been fixed in bl_common.h.

2019-01-23plat/arm: Save BL2 descriptors to reserved memory.Sathees Balya
On ARM platforms, the BL2 memory can be overlaid by BL31/BL32. The memory descriptors describing the list of executable images are created in BL2 R/W memory, which could be possibly corrupted later on by BL31/BL32 due to overlay. This patch creates a reserved location in SRAM for these descriptors and are copied over by BL2 before handing over to next BL image. Also this patch increases the PLAT_ARM_MAX_BL2_SIZE for juno when TBBR is enabled.

2019-01-15plat/arm: Fix header dependenciesAntonio Nino Diaz
From now on, platform_def.h must include any header with definitions that are platform-specific (like arm_def.h) and the included headers mustn't include back platform_def.h, and shouldn't be used by other files. Only platform_def.h should be included in other files. This will ensure that all needed definitions are present, rather than needing to include all the headers in all the definitions' headers just in case. This also prevents problems like cyclic dependencies. Change-Id: I9d3cf4d1de4b956fa035c79545222697acdaf5ca Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

2019-01-04Sanitise includes across codebaseAntonio Nino Diaz
Enforce full include path for includes. Deprecate old paths. The following folders inside include/lib have been left unchanged: - include/lib/cpus/${ARCH} - include/lib/el3_runtime/${ARCH} The reason for this change is that having a global namespace for includes isn't a good idea. It defeats one of the advantages of having folders and it introduces problems that are sometimes subtle (because you may not know the header you are actually including if there are two of them). For example, this patch had to be created because two headers were called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: 46f9b2c3a282 ("drivers: add tzc380 support"). This problem was introduced in commit 4ecca33988b9 ("Move include and source files to logical locations"). At that time, there weren't too many headers so it wasn't a real issue. However, time has shown that this creates problems. Platforms that want to preserve the way they include headers may add the removed paths to PLAT_INCLUDES, but this is discouraged.

On SGI platforms that include Ares CPUs, the 'CORE_PWRDN_EN' bit of 'CPUPWRCTLR_EL1' register requires an explicit write to clear it to enable hotplug and idle to function correctly.
