common: Move ARM cache operations out of common.h

2019-12-02T23:24:58Z

These functions are CPU-related and do not use driver model. Move them to cpu_func.h Signed-off-by: Simon Glass Reviewed-by: Daniel Schwierzeck Reviewed-by: Tom Rini

remoteproc: k3_arm64: Enable DM_FLAG_DEFAULT_PD_CTRL_OFF

2019-10-15T14:40:03Z

Enable DM_FLAG_DEFAULT_PD_CTRL_OFF for arm64 remote core so that pd can be enabled after loading the image. Signed-off-by: Lokesh Vutla Reviewed-by: Simon Glass

remoteproc: Introduce K3 C66 and C71 remoteproc driver

2019-10-11T14:07:34Z

Certain SoCs with K3 architecture have integrated a C66 Corepac DSP subsystem and an advanced C71 DSPs. Introduce a remoteproc driver that that does take care of loading an elf to any of the specified DSPs and start it. Signed-off-by: Lokesh Vutla Signed-off-by: Suman Anna

remoteproc: Introduce K3 remoteproc driver for R5F subsystem

2019-10-11T14:07:34Z

SoCs with K3 architecture have an integrated Arm Cortex-R5F subsystem that is comprised of dual-core Arm Cortex-R5F processor cores. This R5 subsytem can be configured at boot time to be either run in a LockStep mode or in an Asymmetric Multi Processing (AMP) fashion in Split-mode. This subsystem has each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - TCMA and TCMB. Add a remoteproc driver to support this subsystem to be able to load and boot the R5 cores primarily in LockStep mode or split mode. Signed-off-by: Lokesh Vutla Signed-off-by: Suman Anna

remoteproc: tisci_proc: Add helper api for controlling core power domain

2019-10-11T14:07:34Z

Power domain for the remote cores needs to be handled in a right sequence as mandated by the spec. Introduce tisci helper apis that can control power-domains of remote cores. TISCI clients can use this api and control the remote cores power domain instead of hooking it to power-domain layer. Signed-off-by: Lokesh Vutla

remoteproc: elf_loader: Introduce rproc_elf_get_boot_addr() api

2019-10-11T14:07:34Z

Introduce rproc_elf_get_boot_addr() that returns the entry point of the elf file. This api auto detects the 64/32 bit elf file and returns the boot addr accordingly. Signed-off-by: Lokesh Vutla

remoteproc: elf_loader: Introduce a common elf loader and checker functions

2019-10-11T14:07:34Z

Introduce a common remoteproc elf loader and checker functions that automatically detects the 64 bit elf file or 32 bit elf file and loads/checks the sections accordingly. Signed-off-by: Lokesh Vutla Reviewed-by: Fabien Dessenne

remoteproc: elf-loader: Add 64 bit elf loading support

2019-10-11T14:07:34Z

The current rproc-elf-loader supports loading of only 32 bit elf files. Introduce support for loading of 64 bit elf files in rproc-elf-loader. Signed-off-by: Lokesh Vutla Reviewed-by: Fabien Dessenne

remoteproc: elf_loader: Always check the validity of the image before loading

2019-10-11T14:07:34Z

rproc_elf32_load_image() rely on user to send a valid address for elf loading. Instead do a sanity check on the address passed by user. This will help all rproc elf users to not call sanity_check explicitly before calling elf_loading. Signed-off-by: Lokesh Vutla Reviewed-by: Fabien Dessenne

remoteproc: ops: Add elf section size as input parameter to device_to_virt api

2019-10-11T14:07:33Z

Introduce a new parameter "size" that accepts size of the region to remoteproc ops callback device_to_virt(). This can enforce more checks on the region that device_to_virt() is dealing with. Signed-off-by: Lokesh Vutla Tested-by: Fabien Dessenne Reviewed-by: Fabien Dessenne
