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.

2019-01-04Sanitise 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.

2018-10-23tzc: Fix MISRA defectsAntonio Nino Diaz
The definitions FAIL_CONTROL_*_SHIFT were incorrect, they have been fixed. The types tzc_region_attributes_t and tzc_action_t have been removed and replaced by unsigned int because it is not allowed to do logical operations on enums. Also, fix some address definitions in arm_def.h. Change-Id: Id37941d76883f9fe5045a5f0a4224c133c504d8b Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>
2018-04-09DMC500: Add platform support to set system interface countAmit Daniel Kachhap
Some low end platforms using DMC500 memory controller do not have CCI(Cache Coherent Interconnect) interface and only have non-coherent system interface support. Hence this patch makes the system interface count configurable from the platforms. Change-Id: I6d54c90eb72fd18026c6470c1f7fd26c59dc4b9a Signed-off-by: Amit Daniel Kachhap <amit.kachhap@arm.com>

2016-04-12Use unsigned long long instead of uintptr_t in TZC400/DMC500 driversYatharth Kochar
Currently the `tzc400_configure_region` and `tzc_dmc500_configure_region` functions uses uintptr_t as the data type for `region_top` and `region_base` variables, which will be converted to 32/64 bits for AArch32/AArch64 respectively. But the expectation is to keep these addresses at least 64 bit. This patch modifies the data types to make it at least 64 bit by using unsigned long long instead of uintptr_t for the `region_top` and `region_base` variables. It also modifies the associated macros `_tzc##fn_name##_write_region_xxx` accordingly. Change-Id: I4e3c6a8a39ad04205cf0f3bda336c3970b15a28b
2016-03-31Add ARM CoreLink DMC-500 driver to program TrustZone protectionVikram Kanigiri
The ARM CoreLink DMC-500 Dynamic Memory Controller provides the programmable address region control of a TrustZone Address Space Controller. The access permissions can be defined for eight separate address regions plus a background or default region. This patch adds a DMC-500 driver to define address regions and program their access permissions as per ARM 100131_0000_02_en (r0p0) document. Change-Id: I9d33120f9480d742bcf7937e4b876f9d40c727e6
