To make software license auditing simpler, use SPDX[0] license identifiers instead of duplicating the license text in every file.

Many asserts depend on code that is conditionally compiled based on the DEBUG define. This patch modifies the conditional inclusion of such code so that it is based on the ENABLE_ASSERTIONS build option.

Due to incorrect conditional compilation checks, bakery locks were excluded from the CCN driver and the power controller driver for FVP when BL32 was built as the EL3 Runtime Software in AArch32 mode. This patch corrects the same. Change-Id: Ib1f163d9167a5c38e4d622232c4835cad9c235aa Signed-off-by: Soby Mathew <soby.mathew@arm.com>

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>

This patch reworks type usage in generic code, drivers and ARM platform files to make it more portable. The major changes done with respect to type usage are as listed below: * Use uintptr_t for storing address instead of uint64_t or unsigned long. * Review usage of unsigned long as it can no longer be assumed to be 64 bit. * Use u_register_t for register values whose width varies depending on whether AArch64 or AArch32. * Use generic C types where-ever possible. In addition to the above changes, this patch also modifies format specifiers in print invocations so that they are AArch64/AArch32 agnostic. Only files related to upcoming feature development have been reworked. Change-Id: I9f8c78347c5a52ba7027ff389791f1dad63ee5f8

This patch adds the API `ccn_get_part0_id` to query the PART0 ID from the PERIPHERAL_ID 0 register in the CCN driver. This ID allows to distinguish the variant of CCN present on the system and possibly enable dynamic configuration of the IP based on the variant. Also added an assert in `ccn_master_to_rn_id_map()` to ensure that the master map bitfield provided by the platform is within the expected interface id.

Currently, `ccn_snoop_dvm_domain_common()` is responsible for providing a bitmap of HN-F and HN-I nodes in the interconnect. There is a request node (RN) corresponding to the master interface (e.g. cluster) that needs to be added or removed from the snoop/DVM domain. This request node is removed from or added to each HN-F or HN-I node present in the bitmap depending upon the type of domain. The above logic is incorrect when participation of a master interface in the DVM domain has to be managed. The request node should be removed from or added to the single Miscellaneous Node (MN) in the system instead of each HN-I node. This patch fixes this by removing the intermediate `ccn_snoop_dvm_domain_common()` and instead reads the MN registers to get the needed node Id bitmap for snoop(HN-F bitmap) and DVM(MN bitmap) domains. Additionally, it renames `MN_DDC_SET_OFF` to `MN_DDC_SET_OFFSET` to be inline with other macros. Change-Id: Id896046dd0ccc5092419e74f8ac85e31b104f7a4

This patch adds a device driver which can be used to program the following aspects of ARM CCN IP: 1. Specify the mapping between ACE/ACELite/ACELite+DVM/CHI master interfaces and Request nodes. 2. Add and remove master interfaces from the snoop and dvm domains. 3. Place the L3 cache in a given power state. 4. Configuring system adress map and enabling 3 SN striping mode of memory controller operation. Change-Id: I0f665c6a306938e5b66f6a92f8549b529aa8f325
