2023-01-31T14:46:39+00:00

The RESET2 hook is a PSCI v1.1 functionality, rename the macro accordinly.
Add missing handler for the RESET2 hook, so it can be implemented by U-Boot.

arm: Don't include common.h in header files

2020-05-18T18:54:24+00:00

It is bad practice to include common.h in other header files since it can
bring in any number of superfluous definitions. It implies that some C
files don't include it and thus may be missing CONFIG options that are set
up by that file. The C files should include these themselves.

Update some header files in arch/arm to drop this.

arm: cpu: armv8: add support for arm psci reset2.

2020-01-10T19:18:26+00:00

Current U-Boot has only support for psci reset.
Adding support for arm psci reset2 allows passing of reset level
and other platform sepcific parameters like strap settings
to lowlevel psci implementation.

psci: arm: remove armv7 function psci_save_target_pc

2018-05-07T15:52:55+00:00

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.

arm: psci: save context id for cpu_on PSCI command

2018-05-07T15:45:15+00:00

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

ARMv8: Add basic PSCI framework

2016-12-15T19:57:44+00:00

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.

armv7: psci: make v7_flush_dcache_all public for all psci code

2016-09-14T21:07:29+00:00

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

2016-08-02T16:47:49+00:00

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.
