2019-02-27Add support for pointer authenticationAntonio Nino Diaz
The previous commit added the infrastructure to load and save ARMv8.3-PAuth registers during Non-secure <-> Secure world switches, but didn't actually enable pointer authentication in the firmware. This patch adds the functionality needed for platforms to provide authentication keys for the firmware, and a new option (ENABLE_PAUTH) to enable pointer authentication in the firmware itself. This option is disabled by default, and it requires CTX_INCLUDE_PAUTH_REGS to be enabled.

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.

However, the system power domain level can be different for CSS platforms that use multi-threaded CPUs.

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>
2018-11-07Arm platforms: Fix DRAM address macrosSandrine Bailleux
On AArch32, ARM_DRAM1_BASE and ARM_DRAM1_SIZE constants are currently 32-bit values (because they are suffixed with UL and the value 0x80000000 fits in a unsigned long int, i.e. a 32-bit value). When summing them up, the result overflows the maximum value that can be encoded in a 32-bit value so it wraps around and does not result in the expected value. This patch changes the suffix of these constants into ULL so that they always are 64-bit values.

2018-10-26xlat: Fix compatibility between v1 and v2Antonio Nino Diaz
There are several platforms using arm_setup_page_tables(), which is supposed to be Arm platform only. This creates several dependency problems between platforms. This patch adds the definition XLAT_TABLES_LIB_V2 to the xlat tables lib v2 makefile. This way it is possible to detect from C code which version is being used and include the correct header. The file arm_xlat_tables.h has been renamed to xlat_tables_compat.h and moved to a common folder. This way, when in doubt, this header can be used to guarantee compatibility, as it includes the correct header based on XLAT_TABLES_LIB_V2. This patch also removes the usage of ARM_XLAT_TABLES_V1 from QEMU (so that is now locked in xlat lib v2) and ZynqMP (where it was added as a workaround).

This file is shared between FVP and all CSS platforms. While it may be true that some definitions can be common, it doesn't make sense conceptually. For example, the stack size depends on the platform and so does the SRAM size. After removing them, there are not enough common definitions to justify having this header, so the other definitions have been moved to the platform_def.h of FVP, board_css_def.h and arm_def.h.

Once BL31 has been initialized the memory can be remapped to RW data so that it can be used for secondary cores stacks. By moving code from .text to .text.init the size of the BL31 image is decreased by a page. Split arm_common.ld.S into two linker scripts, one for tzc_dram (arm_tzc_dram.ld.S) and one for reclaiming initialization code (arm_reclaim_init.ld.S) so that platforms can chose which memory regions they wish to include.

The definitions have been copied to each platform's platform_def.h. Juno was already using the ones in platform_def.h, so there have been no changes.
