tlkd: support new TLK SMCs

2019-01-31T16:46:54Z

This patch adds support to handle following TLK SMCs: {TLK_SS_REGISTER_HANDLER, TLK_REGISTER_NS_DRAM_RANGES, TLK_SET_ROOT_OF_TRUST} These SMCs need to be supported in ATF in order to forward them to TLK. Otherwise, these functionalities won't work. Brief: TLK_SS_REGISTER_HANDLER: This SMC is issued by TLK Linux Driver to set up secure storage buffers. TLK_REGISTER_NS_DRAM_RANGES: Cboot performs this SMC during boot to pass NS memory ranges to TLK. TLK_SET_ROOT_OF_TRUST: Cboot performs this SMC during boot to pass Verified Boot parameters to TLK.

Sanitise includes across codebase

2019-01-04T10:43:17Z

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.

Standardise header guards across codebase

2018-11-08T10:20:19Z

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

spd: tlkd: support for "NS memory ranges" function ID

This patch adds support to receive function ID with NS world's memory ranges to provide the memory snapshot to TLK. Signed-off-by: Varun Wadekar

Migrate secure payload dispatchers to new SMC terminology

2017-05-04T20:23:06Z

Since Issue B (November 2016) of the SMC Calling Convention document standard SMC calls are renamed to yielding SMC calls to help avoid confusion with the standard service SMC range, which remains unchanged. http://infocenter.arm.com/help/topic/com.arm.doc.den0028b/ARM_DEN0028B_SMC_Calling_Convention.pd A previous patch introduced a new define for yielding SMC call type. This patch updates the secure payload dispatchers (except the TSPD) to use this new define and also migrates the code to use the new terminology.

Use SPDX license identifiers

2017-05-03T08:39:28Z

To make software license auditing simpler, use SPDX[0] license identifiers instead of duplicating the license text in every file. NOTE: Files that have been imported by FreeBSD have not been modified. [0]: https://spdx.org/ Change-Id: I80a00e1f641b8cc075ca5a95b10607ed9ed8761a Signed-off-by: dp-arm

Move defines in utils.h to utils_def.h to fix shared header compile issues

2017-04-29T15:30:05Z

utils.h is included in various header files for the defines in it. Some of the other header files only contain defines. This allows the header files to be shared between host and target builds for shared defines. Recently types.h has been included in utils.h as well as some function prototypes. Because of the inclusion of types.h conflicts exist building host tools abd these header files now. To solve this problem, move the defines to utils_def.h and have this included by utils.h and change header files to only include utils_def.h and not pick up the new types.h being introduced. Fixes ARM-software/tf-issues#461 Signed-off-by: Scott Branden Remove utils_def.h from utils.h This patch removes utils_def.h from utils.h as it is not required. And also makes a minor change to ensure Juno platform compiles. Change-Id: I10cf1fb51e44a8fa6dcec02980354eb9ecc9fa29

Resolve build errors flagged by GCC 6.2

2017-01-26T13:47:37Z

With GCC 6.2 compiler, more C undefined behaviour is being flagged as warnings, which result in build errors in ARM TF build. The specific issue that this patch resolves is the use of (1 << 31), which is predominantly used in case statements, where 1 is represented as a signed int. When shifted to msb the behaviour is undefined. The resolution is to specify 1 as an unsigned int using a convenience macro ULL(). A duplicate macro MAKE_ULL() is replaced.

Send power management events to the Trusted OS (TLK)

2015-09-30T05:08:28Z

This patch adds PM handlers to TLKD for the system suspend/resume and system poweroff/reset cases. TLK expects all SMCs through a single handler, which then fork out into multiple handlers depending on the SMC. We tap into the same single entrypoint by restoring the S-EL1 context before passing the PM event via register 'x0'. On completion of the PM event, TLK sends a completion SMC and TLKD then moves on with the PM process. Signed-off-by: Varun Wadekar

Pass arguments/results between EL3/S-EL1 via CPU registers (x0-x7)

2015-04-13T16:17:56Z

This patch removes the need for a shared buffer between the EL3 and S-EL1 levels. We now use the CPU registers, x0-x7, while passing data between the two levels. Since TLK is a 32-bit Trusted OS, tlkd has to unpack the arguments in the x0-x7 registers. TLK in turn gets these values via r0-r7. Signed-off-by: Varun Wadekar
