As the core now deals with the lack of a resource table, remove the dangling custom dummy implementations of find_rsc_table from drivers. Reviewed-By: Loic Pallardy <loic.pallardy@st.com> Tested-By: Loic Pallardy <loic.pallardy@st.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2018-01-15remoteproc: Merge rproc_ops and rproc_fw_opsBjorn Andersson1-15/+7
There are currently a few different schemes used for overriding fw_ops or parts of fw_ops. Merge fw_ops into rproc_ops and expose the default ELF-loader symbols so that they can be assigned by the drivers. To keep backwards compatibility with the "default" case, a driver not specifying the "load" operation is assumed to want the full ELF-loader suit of functions.

2017-01-18drivers: remoteproc: constify rproc_ops structuresBhumika Goyal1-1/+1
Declare rproc_ops structures as const as they are only passed as an argument to the function rproc_alloc. This argument is of type const, so rproc_ops structures having this property can be declared const too.

2016-10-18remoteproc: st_slim_rproc: add a slimcore rproc driverPeter Griffin1-0/+364
slim core is used as a basis for many IPs in the STi chipsets such as fdma and demux. To avoid duplicating the elf loading code in each device driver a slim rproc driver has been created. This driver is designed to be used by other device drivers such as fdma, or demux whose IP is based around a slim core. The device driver can call slim_rproc_alloc() to allocate a slim rproc and slim_rproc_put() when finished. This driver takes care of ioremapping the slim registers (dmem, imem, slimcore, peripherals), whose offsets and sizes can change between IP's. It also obtains and enables any clocks used by the device. This approach avoids having a double mapping of the registers as slim_rproc does not register its own platform device. It also maps well to device tree abstraction as it allows us to have one dt node for the whole device. All of the generic rproc elf loading code can be reused, and we provide start() stop() hooks to start and stop the slim core once the firmware has been loaded. This has been tested successfully with fdma driver. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
