psci: arm: remove armv7 function psci_save_target_pc

2018-05-07T15:52:55Z

This function is no more used, and replaced by psci_save which save also context id as requested by PSCI requirements. Even if the context id is not used by Linux, it should be saved and restored in r0 when the CPU_ON is performed. Signed-off-by: Patrick Delaunay

arm: psci: save context id for cpu_on PSCI command

2018-05-07T15:45:15Z

Save and use the 3rd parameter of PSCI CPU_ON request: context_id. The context_id parameter is only meaningful to the caller. U-Boot PSCI preserves a copy of the value passed in this parameter. Following wakeup from a powerdown state, U-BOOT PSCI places this value in R0 when it first enters the OS. NB: this context id is not (yet?) used by Linux but it is mandatory to be PSCI compliant. update armv7 psci functions: - psci_save_target_pc(): keep for backward compatibility with current platform (only save PC and force context id to 0) => should be removed when all platform migrate to the new API - psci_save(): new API to use by ARMv7 platform with PSCI, save pc (= entry_point_address) and context_id Signed-off-by: Patrick Delaunay Reviewed-by: Stephen Warren Reviewed-by: Masahiro Yamada

ARMv8: Add basic PSCI framework

2016-12-15T19:57:44Z

This patch introduces a generic ARMv8 PSCI framework, with all functions returning a dummy ARM_PSCI_RET_NI (Not Implemented), then it is up to each platform to implement their own functions based on this framework. Signed-off-by: Hongbo Zhang Reviewed-by: Tom Rini Reviewed-by: York Sun

armv7: psci: make v7_flush_dcache_all public for all psci code

2016-09-14T21:07:29Z

The v7_flush_dcache_all function will be called by ls102xa platform system suspend, it is necessary to make it a public call instead of a local one, but changing the LENTRY to ENTRY isn't enough, because there is another one using the same name, so this one gets a psci_ prefix.

arm/PSCI: Fixed the backward compatiblity issue

2016-08-02T16:47:49Z

Appended the compatible strings of old version PSCI to the latest version supported. And there are some psci functions' property must be added to DT only for psci version 0.1, including cpu_on, cpu_off, cpu_suspend, migrate. Note, ARMv8 Secure Firmware Framework doesn't support PSCI ver 0.1. Signed-off-by: Hou Zhiqiang Reviewed-by: York Sun

ARMv7: PSCI: ls102xa: check target CPU ID before further operations

2016-07-26T16:02:44Z

ARMv7: PSCI: add PSCI v1.0 functions skeleton

2016-07-26T16:02:39Z

This patch adds all the PSCI v1.0 functions in to the common framework, with all the functions returning "not implemented" by default, as a common framework all the dummy functions are added here, it is up to every platform developer to decide which version of PSCI and which functions to implement.

ARM: PSCI: Make psci_get_cpu_stack_top local to armv7/psci.S

2016-07-15T13:54:58Z

Now that we have a secure data section for storing variables, there should be no need for platform code to get the stack address. Make psci_get_cpu_stack_top a local function, as it should only be used in armv7/psci.S and only by psci_stack_setup. Signed-off-by: Chen-Yu Tsai Signed-off-by: Hans de Goede
