The Texas Instrument's Keystone 2 family of SoCs has 1 or more TMS320C66x DSP Core Subsystems (C66x CorePacs). Each subsystem has a C66x Fixed/Floating-Point DSP Core, with 32KB of L1P and L1D SRAMs, that can be configured and partitioned as either RAM and/or Cache, and 1 MB of L2 SRAM. The CorePac also includes an Internal DMA (IDMA), External Memory Controller (EMC), Extended Memory Controller (XMC) with a Memory Protection and Address Extension (MPAX) unit, a Bandwidth Management (BWM) unit, an Interrupt Controller (INTC) and a Powerdown Controller (PDC). A new remoteproc module is added to perform the device management of these DSP devices. The driver expects the firmware names to be of the form "keystone-dsp<X>-fw", where X is the corresponding DSP number, and uses the standard remoteproc core ELF loader. The support is limited to images only using the DSP internal memories at the moment. This remoteproc driver is also designed to work with virtio, and uses the IPC Generation registers for performing the virtio signalling and getting notified of exceptions. The driver currently supports the 66AK2H/66AK2K, 66AK2L and 66AK2E SoCs. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Sam Nelson <sam.nelson@ti.com> Signed-off-by: Andrew F.
