Antonio Nino Diaz	09d40e0e08	Sanitise includes across codebase 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: `e0ea0928d5` ("Fix gpio includes of mt8173 platform to avoid collision."). More recently, this patch has had similar problems: `46f9b2c3a2` ("drivers: add tzc380 support"). This problem was introduced in commit `4ecca33988` ("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.

Masahiro Yamada	3d8256b2a1	Use #ifdef for IMAGE_BL* instead of #if One nasty part of ATF is some of boolean macros are always defined as 1 or 0, and the rest of them are only defined under certain conditions. For the former group, "#if FOO" or "#if !FOO" must be used because "#ifdef FOO" is always true. (Options passed by $(call add_define,) are the cases.) For the latter, "#ifdef FOO" or "#ifndef FOO" should be used because checking the value of an undefined macro is strange. Here, IMAGE_BL* is handled by make_helpers/build_macro.mk like follows: $(eval IMAGE := IMAGE_BL$(call uppercase,$(3))) $(OBJ): $(2) @echo " CC $$<" $$(Q)$$(CC) $$(TF_CFLAGS) $$(CFLAGS) -D$(IMAGE) -c $$< -o $$@ This means, IMAGE_BL* is defined when building the corresponding image, but undefined for the other images. So, IMAGE_BL* belongs to the latter group where we should use #ifdef or #ifndef. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>	8 years ago
Sandrine Bailleux	ed81f3ebbf	Introduce utils.h header file 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	8 years ago
Tony Xie	6fba6e0490	Support for Rockchip's family SoCs This patch adds to support the RK3368 and RK3399 SoCs. RK3368/RK3399 is one of the Rockchip family SoCs, which is an multi-cores ARM SoCs. This patch adds support to boot the Trusted Firmware on RK3368/RK3399 SoCs, and adds support to boot secondary CPUs, enter/exit core power states for all CPUs in the slow/fast clusters. This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs) * Support arm gicv2 & gicv3. * Boot up multi-cores CPU. * Add generic CPU helper functions. * Support suspend/resume. * Add system_off & system_reset implementation. * Add delay timer platform implementation. * Support the new porting interface for the PSCI implementation.

Achin Gupta	27573c59a6	Rework use of ARM GIC drivers on ARM platforms Suport for ARM GIC v2.0 and v3.0 drivers has been reworked to create three separate drivers instead of providing a single driver that can work on both versions of the GIC architecture. These drivers correspond to the following software use cases: 1. A GICv2 only driver that can run only on ARM GIC v2.0 implementations e.g. GIC-400 2. A GICv3 only driver that can run only on ARM GIC v3.0 implementations e.g. GIC-500 in a mode where all interrupt regimes use GICv3 features 3. A deprecated GICv3 driver that operates in legacy mode. This driver can operate only in the GICv2 mode in the secure world. On a GICv3 system, this driver allows normal world to run in either GICv3 mode (asymmetric mode) or in the GICv2 mode. Both modes of operation are deprecated on GICv3 systems. ARM platforms implement both versions of the GIC architecture. This patch adds a layer of abstraction to help ARM platform ports chose the right GIC driver and corresponding platform support. This is as described below: 1. A set of ARM common functions have been introduced to initialise the GIC and the driver during cold and warm boot. These functions are prefixed as "plat_arm_gic_". Weak definitions of these functions have been provided for each type of driver. 2. Each platform includes the sources that implement the right functions directly into the its makefile. The FVP can be instantiated with different versions of the GIC architecture. It uses the FVP_USE_GIC_DRIVER build option to specify which of the three drivers should be included in the build. 3. A list of secure interrupts has to be provided to initialise each of the three GIC drivers. For GIC v3.0 the interrupt ids have to be further categorised as Group 0 and Group 1 Secure interrupts. For GIC v2.0, the two types are merged and treated as Group 0 interrupts. The two lists of interrupts are exported from the platform_def.h. The lists are constructed by adding a list of board specific interrupt ids to a list of ids common to all ARM platforms and Compute sub-systems. This patch also makes some fields of `arm_config` data structure in FVP redundant and these unused fields are removed. Change-Id: Ibc8c087be7a8a6b041b78c2c3bd0c648cd2035d8	9 years ago
