DRA7xx/AM57xx SoCs have two IPU and up to two DSP processor subsystems for offloading different computation algorithms. The IPU processor subsystem contains dual-core ARM Cortex-M4 processors, and is very similar to those on OMAP5. The DSP processor subsystem is based on the TI's standard TMS320C66x DSP CorePac core. Support has been added to the OMAP remoteproc driver through new DRA7xx specific compatibles for properly probing and booting all the different processor subsystem instances on DRA7xx/AM57xx SoCs - IPU1, IPU2, DSP1 & DSP2. A build dependency with SOC_DRA7XX is added to enable the driver to be built in DRA7xx-only configuration. The DSP boot address programming needed enhancement for DRA7xx as the boot register fields are different on DRA7 compared to OMAP4 and OMAP5 SoCs. The register on DRA7xx contains additional fields within the register and the boot address bit-field is right-shifted by 10 bits. The internal memory parsing logic has also been updated to compute the device addresses for the L2 RAM for DSP devices using relative addressing logic, and to parse two additional RAMs at L1 level - L1P and L1D. This allows the remoteproc driver to support loading into these regions for a small subset of firmware images requiring as such. The most common usage would be to use the L1 programmable RAMs as L1 Caches. The firmware lookup logic also has to be adjusted for DRA7xx as there are (can be) more than one instance of both the IPU and DSP remote processors for the first time in OMAP4+ SoCs.
