dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46Z

At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46Z

At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

remoteproc: elf_loader: fix program header parsing

2020-01-24T16:19:52Z

Fix an issue where some sections are never loaded : if p_type is different from PT_LOAD the phdr pointer must be incremented. Signed-off-by: Fabien Dessenne Acked-by: Suman Anna

remoteproc: stm32: track the coprocessor state in a backup register

2020-01-07T16:13:25Z

Update the dedicated backup register to track the coprocessor state and rely on that register to compute the .is_running() value (which expects a return value of 0 -not 1- if the processor is running). Signed-off-by: Fabien Dessenne Acked-by: Patrick Delaunay

remoteproc: elf_loader: Add elf resource table load support

2020-01-07T16:13:25Z

Add rproc_elf_load_rsc_table(), which searches for a resource table in an elf64/elf32 image, and if found, copies it to device memory. Add also the elf32 and elf64 variants of this API. Add a test for this. Signed-off-by: Fabien Dessenne Acked-by: Patrick Delaunay Reviewed-by: Lokesh Vutla

common: Move ARM cache operations out of common.h

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
