drivers/remoteproc: remove depends on CONFIG_EXPERIMENTAL The CONFIG_EXPERIMENTAL config item has not carried much meaning for a while now and is almost always enabled by default. As agreed during the Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

remoteproc: add framework for controlling remote processors Modern SoCs typically employ a central symmetric multiprocessing (SMP) application processor running Linux, with several other asymmetric multiprocessing (AMP) heterogeneous processors running different instances of operating system, whether Linux or any other flavor of real-time OS. Booting a remote processor in an AMP configuration typically involves: - Loading a firmware which contains the OS image - Allocating and providing it required system resources (e.g. memory) - Programming an IOMMU (when relevant) - Powering on the device This patch introduces a generic framework that allows drivers to do that. In the future, this framework will also include runtime power management and error recovery. Based on (but now quite far from) work done by Fernando Guzman Lugo <fernando.lugo@ti.com>. ELF loader was written by Mark Grosen <mgrosen@ti.com>, based on msm's Peripheral Image Loader (PIL) by Stephen Boyd <sboyd@codeaurora.org>. Designed with Brian Swetland <swetland@google.com>.

remoteproc/omap: add a remoteproc driver for OMAP4 Add a remoteproc driver for OMAP4, so we can boot the dual-M3 and and DSP subsystems. Use the omap_device_* API to control the hardware state, and utilize the OMAP mailbox to interrupt the remote processor when a new message is pending (the mailbox payload is used to tell it which virtqueue was the message placed in). Conversely, when an inbound mailbox message arrives, tell the remoteproc core which virtqueue is triggered. Later we will also use the mailbox payload to signal omap-specific events like remote crashes (which will be used to trigger remoteproc recovery) and power management transitions. At that point we will also extend the remoteproc core to support this.

mailbox/omap: move the OMAP mailbox framework to drivers The mailbox hardware (in OMAP) uses a queued mailbox interrupt mechanism that provides a communication channel between processors through a set of registers and their associated interrupt signals by sending and receiving messages. The OMAP mailbox framework/driver code is moved to be under drivers/mailbox, in preparation for adapting to a common mailbox driver framework. This allows the build for OMAP mailbox to be enabled (it was disabled during the multi-platform support). As part of the migration from plat and mach code: - Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers. - mailbox.h under plat-omap/plat/include has been split into a public and private header files. The public header has only the API related functions and types. - The module name mailbox.ko from plat-omap is changed to omap-mailbox.ko - The module name mailbox_mach.ko from mach-omapX is changed as mailbox_omap1.ko for OMAP1 mailbox_omap2.ko for OMAP2+ Cc: Tony Lindgren <tony@atomide.com> [gregkh@linuxfoundation.org: ack for staging part] Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Omar Ramirez Luna <omar.ramirez@copitl.com> Signed-off-by: Suman Anna <s-anna@ti.com>

remoteproc/wkup_m3: add a remoteproc driver for TI Wakeup M3 Add a remoteproc driver to load the firmware and boot a small Wakeup M3 processor present on TI AM33xx and AM43xx SoCs. This Wakeup M3 remote processor is an integrated Cortex M3 that allows the SoC to enter the lowest possible power state by taking control from the MPU after it has gone into its own low power state and shutting off any additional peripherals. The Wakeup M3 processor has two internal memory regions - 16 kB of unified instruction memory called UMEM used to store executable code, and 8 kB of data memory called DMEM used for all data sections. The Wakeup M3 processor executes its code entirely from within the UMEM and uses the DMEM for any data. It does not use any external memory or any other external resources. The device address view has the UMEM at address 0x0 and DMEM at address 0x80000, and these are computed automatically within the driver based on relative address calculation from the corresponding device tree IOMEM resources. These device addresses are used to aid the core remoteproc ELF loader code to properly translate and load the firmware segments through the .rproc_da_to_va ops.
