psci: Fix warnings when compiling with W=1

2019-07-24T18:15:38Z

This patch solves the following warnings: arch/arm/mach-stm32mp/psci.c: warning: no previous prototype for ‘psci_set_state’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_arch_cpu_entry’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_features’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_version’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_affinity_info’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_migrate_info_type’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_cpu_on’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_cpu_off’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_system_reset’ [-Wmissing-prototypes] warning: no previous prototype for ‘psci_system_off’ [-Wmissing-prototypes] Signed-off-by: Patrick Delaunay

arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A

2018-05-07T19:53:24Z

Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under armv7 folder. This led to a misconception of creating separate folders for armv7m and armv7r. There is no reason to create separate folder for other armv7 based architectures when it can co-exist with few Kconfig symbols. As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and can co exist in the same folder.

arm: make save_boot_params_ret prototype visible for AArch64

2017-11-21T22:57:22Z

The save_boot_params_ret() prototype (for those of us, that have a valid SP on entry and can implement save_boot_params() in C), was previously only defined for !defined(CONFIG_ARM64). This moves the declaration to a common block to ensure the prototype is available to everyone that might need it. Signed-off-by: Philipp Tomsich Tested-by: Andy Yan

armv8: layerscape: Enable falcon boot

2017-10-09T15:48:45Z

Add jump_to_image_linux() for arm64. Add "noreturn" flag to armv8_switch_to_el2(). Add hooks to fsl-layerscape to enable falcon boot. Signed-off-by: York Sun Reviewed-by: Simon Glass Reviewed-by: Łukasz Majewski Tested-by: Łukasz Majewski

arm: Support cache invalidate

2017-05-12T02:03:39Z

At present there is not operation to invalidate a cache range. This seems to be needed to fill out the cache operations. Add an implementation based on the flush operation. Signed-off-by: Simon Glass Reviewed-by: York Sun

armv8: mmu: Add a function to change mapping attributes

2017-03-14T15:44:03Z

Function mmu_change_region_attr() is added to change existing mapping with updated PXN, UXN and memory type. This is a break-before-make process during which the mapping becomes fault (invalid) before final attributres are set. Signed-off-by: York Sun

armv8: aarch64: Fix the warning about x1-x3 nonzero issue

2017-01-18T17:29:33Z

For 64-bit kernel, there is a warning about x1-x3 nonzero in violation of boot protocol. To fix this issue, input argument 4 is added for armv8_switch_to_el2 and armv8_switch_to_el1. The input argument 4 will be set to the right value, such as zero. Signed-off-by: Alison Wang Reviewed-by: Alexander Graf Tested-by: Ryan Harkin Tested-by: Michal Simek Reviewed-by: York Sun

armv8: fsl-layerscape: Support loading 32-bit OS with PSCI enabled

2016-11-22T19:40:24Z

As PSCI and secure monitor firmware framework are enabled, this patch is to support loading 32-bit OS in such case. The default target exception level returned to U-Boot is EL2, so the corresponding work to switch to AArch32 EL2 and jump to 32-bit OS are done in U-Boot and secure firmware together.
