plat/arm: Fix header dependencies

2019-01-15T14:19:50Z

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

plat/arm: Use `mov_imm` macro to load immediate values

CSS: Changes for SDS framework

2017-09-06T14:32:20Z

This patch does the required changes to enable CSS platforms to build and use the SDS framework. Since SDS is always coupled with SCMI protocol, the preexisting SCMI build flag is now renamed to `CSS_USE_SCMI_SDS_DRIVER` which will enable both SCMI and SDS on CSS platforms. Also some of the workarounds applied for SCMI are now removed with SDS in place. Change-Id: I94e8b93f05e3fe95e475c5501c25bec052588a9c Signed-off-by: Soby Mathew

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

Rework type usage in Trusted Firmware

2016-07-18T16:52:15Z

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

Support for varying BOM/SCPI protocol base addresses in ARM platforms

2016-02-15T11:00:57Z

Current code assumes `SCP_COM_SHARED_MEM_BASE` as the base address for BOM/SCPI protocol between AP<->SCP on all CSS platforms. To cater for future ARM platforms this is made platform specific. Similarly, the bit shifts of `SCP_BOOT_CONFIG_ADDR` are also made platform specific. Change-Id: Ie8866c167abf0229a37b3c72576917f085c142e8

CSS: Put secondary CPUs in a pen when booting an EL3 payload

2015-11-26T21:32:04Z

By default, only the primary CPU is powered on by SCP on CSS platforms. Secondary CPUs are then powered on later using PSCI calls. However, it is possible to power on more than one CPU at boot time using platform specific settings. In this case, several CPUs will enter the Trusted Firmware and execute the cold boot path code. This is currently not supported and secondary CPUs will panic. This patch preserves this behaviour in the normal boot flow. However, when booting an EL3 payload, secondary CPUs are now held in a pen until their mailbox is populated, at which point they jump to this address. Note that, since all CPUs share the same mailbox, they will all be released from their holding pen at the same time and the EL3 payload is responsible to arbitrate execution between CPUs if required.

Allow CSS to redefine function `plat_arm_calc_core_pos`

2015-10-27T02:11:55Z

Currently all ARM CSS platforms which include css_helpers.S use the same strong definition of `plat_arm_calc_core_pos`. This patch allows these CSS platforms to define their own strong definition of this function. * Replace the strong definition of `plat_arm_calc_core_pos` in css_helpers.S with a utility function `css_calc_core_pos_swap_cluster` does the same thing (swaps cluster IDs). ARM CSS platforms may choose to use this function or not. * Add a Juno strong definition of `plat_arm_calc_core_pos`, which uses `css_calc_core_pos_swap_cluster`.

Reorganise PSCI PM handler setup on ARM Standard platforms

2015-10-20T13:11:04Z

This patch does the following reorganization to psci power management (PM) handler setup for ARM standard platform ports : 1. The mailbox programming required during `plat_setup_psci_ops()` is identical for all ARM platforms. Hence the implementation of this API is now moved to the common `arm_pm.c` file. Each ARM platform now must define the PLAT_ARM_TRUSTED_MAILBOX_BASE macro, which in current platforms is the same as ARM_SHARED_RAM_BASE. 2. The PSCI PM handler callback structure, `plat_psci_ops`, must now be exported via `plat_arm_psci_pm_ops`. This allows the common implementation of `plat_setup_psci_ops()` to return a platform specific `plat_psci_ops`. In the case of CSS platforms, a default weak implementation of the same is provided in `css_pm.c` which can be overridden by each CSS platform. 3. For CSS platforms, the PSCI PM handlers defined in `css_pm.c` are now made library functions and a new header file `css_pm.h` is added to export these generic PM handlers. This allows the platform to reuse the adequate CSS PM handlers and redefine others which need to be customized when overriding the default `plat_arm_psci_pm_ops` in `css_pm.c`.

PSCI: Add documentation and fix plat_is_my_cpu_primary()

2015-08-13T22:48:07Z

This patch adds the necessary documentation updates to porting_guide.md for the changes in the platform interface mandated as a result of the new PSCI Topology and power state management frameworks. It also adds a new document `platform-migration-guide.md` to aid the migration of existing platform ports to the new API. The patch fixes the implementation and callers of plat_is_my_cpu_primary() to use w0 as the return parameter as implied by the function signature rather than x0 which was used previously.
