2019-09-10mediatek: mt8183: Support coreboot configurationHung-Te Lin
When built for coreboot, we want to enable coreboot library to have better integration. For example, serial console should be initialized by coreboot_serial instead of hard-coded values. Most coreboot configuration will enable memory console, which needs larger XLAT_TABLES so MAX_XLAT_TABLES is increased; and to support that, TZRAM_SIZE also need to be enlarged.

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.

2019-07-24plat/mediatek/mt81*: Use new bl31_params_parse() helperJulius Werner
The Mediatek MT8173/MT8183 SoCs are prime candidates for switching to the new bl31_params_parse() helper, so switch them over. This will allow BL2 implementations on these platforms to transparently switch over to the version 2 parameter structure.

2019-02-07locks: linker variables to calculate per-cpu bakery lock sizeVarun Wadekar
This patch introduces explicit linker variables to mark the start and end of the per-cpu bakery lock section to help bakery_lock_normal.c calculate the size of the section. This patch removes the previously used '__PERCPU_BAKERY_LOCK_SIZE__' linker variable to make the code uniform across GNU linker and ARM linker.

2019-01-25plat/arm: Sanitise includesAntonio Nino Diaz
Use full include paths like it is done for common includes. This cleanup was started in commit d40e0e08283a ("Sanitise includes across codebase"), but it only cleaned common files and drivers. This patch does the same to Arm platforms. Change-Id: If982e6450bbe84dceb56d464e282bcf5d6d9ab9b 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.

2018-11-08Standardise header guards across codebaseAntonio Nino Diaz
All identifiers, regardless of use, that start with two underscores are reserved. This means they can't be used in header guards. The style that this project is now to use the full name of the file in capital letters followed by 'H'. For example, for a file called "uart_example.h", the header guard is UART_EXAMPLE_H. The exceptions are files that are imported from other projects: - CryptoCell driver - dt-bindings folders - zlib headers Change-Id: I50561bf6c88b491ec440d0c8385c74650f3c106e Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

2018-10-10Replace S-EL3 references by EL3John Tsichritzis
The "Secure" prefix (S-ELx) is valid only for S-EL0 and S-EL1 but is meaningless for EL3, since EL3 is always secure. Hence, the "S" prefix has been removed from wherever it was used as "S-EL3".

2018-07-18Fix types of arch.h definitionsAntonio Nino Diaz
Define the values as unsigned int or unsigned long long based on the actual size of the register. This prevents subtle issues caused by having a type that is too small. For example: #define OPTION_ENABLE 0x3 #define OPTION_SHIFT 32 uint64_t mask = OPTION_ENABLE << OPTION_SHIFT; Because OPTION_ENABLE fits in an int, the value is considered an int. This means that, after shifting it 32 places to the left, the final result is 0. The correct way to define the values is: #define OPTION_ENABLE ULL(0x3) #define OPTION_SHIFT U(32) In this case, the compiler is forced to use a 64 bit value from the start, so shifting it 32 places to the left results in the expected value.

2018-07-11Use ALIGN instead of NEXT in linker scriptsRoberto Vargas
Clang linker doesn't support NEXT. As we are not using the MEMORY command to define discontinuous memory for the output file in any of the linker scripts, ALIGN and NEXT are equivalent. Change-Id: I867ffb9c9a76d4e81c9ca7998280b2edf10efea0 Signed-off-by: Roberto Vargas <roberto.vargas@arm.com>
2018-06-14Make TF UUID RFC 4122 compliantRoberto Vargas
RFC4122 defines that fields are stored in network order (big endian), but TF-A stores them in machine order (little endian by default in TF-A). We cannot change the future UUIDs that are already generated, but we can store all the bytes using arrays and modify fiptool to generate the UUIDs with the correct byte order.

Fix switch statements to comply with MISRA rules
2018-03-27Clean usage of void pointers to access symbolsJoel Hutton
Void pointers have been used to access linker symbols, by declaring an extern pointer, then taking the address of it. This limits symbols values to aligned pointer values. To remove this restriction an IMPORT_SYM macro has been introduced, which declares it as a char pointer and casts it to the required type.

2018-02-27Add comments about mismatched TCR_ELx and xlat tablesAntonio Nino Diaz
When the MMU is enabled and the translation tables are mapped, data read/writes to the translation tables are made using the attributes specified in the translation tables themselves. However, the MMU performs table walks with the attributes specified in TCR_ELx. They are completely independent, so special care has to be taken to make sure that they are the same. This has to be done manually because it is not practical to have a test in the code. Such a test would need to know the virtual memory region that contains the translation tables and check that for all of the tables the attributes match the ones in TCR_ELx. As the tables may not even be mapped at all, this isn't a test that can be made generic. The flags used by enable_mmu_xxx() have been moved to the same header where the functions are. Also, some comments in the linker scripts related to the translation tables have been fixed.

2017-11-29Replace magic numbers in linkerscripts by PAGE_SIZEAntonio Nino Diaz
When defining different sections in linker scripts it is needed to align them to multiples of the page size. In most linker scripts this is done by aligning to the hardcoded value 4096 instead of PAGE_SIZE. This may be confusing when taking a look at all the codebase, as 4096 is used in some parts that aren't meant to be a multiple of the page size.
