ARM: add psci_arch_init() declaration for CONFIG_ARMV7_PSCI

2020-06-02T21:27:04Z

arch/arm/include/asm/system.h declares psci_arch_init(), but it is surrounded by #ifdef CONFIG_ARMV8_PSCI. psci_arch_init() is called for CONFIG_ARMV7_PSCI too. Add the missing function declaration. Signed-off-by: Masahiro Yamada

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

2020-05-18T18:54:24Z

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. Signed-off-by: Simon Glass

arm: caches: add DCACHE_DEFAULT_OPTION

2020-05-01T15:34:01Z

Add the new flags DCACHE_DEFAULT_OPTION to define the default option to use according the compilation flags CONFIG_SYS_ARM_CACHE_*. This new compilation flag allows to simplify dram_bank_mmu_setup() and can be used as third parameter (option=dcache option to select) of mmu_set_region_dcache_behaviour function.

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

2020-01-10T19:18:26Z

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. Signed-off-by: Rajesh Ravi Signed-off-by: Vladimir Olovyannikov

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

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
