arm: dts: k3-j721e-mcu: Add MCU domain R5F cluster node The J721E SoCs have 3 dual-core Arm Cortex-R5F processor (R5FSS) subsystems/clusters. One R5F cluster (MCU_R5FSS0) is present within the MCU domain, and the remaining two clusters are present in the MAIN domain (MAIN_R5FSS0 & MAIN_R5FSS1). Each of these 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. These subsystems have 64 KB each Tightly-Coupled Memory (TCM) internal memories for each core split between two banks - ATCM and BTCM (further interleaved into two banks). There are some IP integration differences from standard Arm R5 clusters such as the absence of an ACP port, presence of an additional TI-specific Region Address Translater (RAT) module for translating 32-bit CPU addresses into larger system bus addresses etc. Add the DT node for the MCU domain R5F cluster/subsystem, the two R5 cores are added as child nodes to the main cluster/subsystem node. The cluster is configured to run in LockStep mode by default, with the ATCMs enabled to allow the R5 cores to execute code from DDR with boot-strapping code from ATCM. The inter-processor communication between the main A72 cores and these processors is achieved through shared memory and Mailboxes.

arm: dts: k3-j721e-mcu-wakeup: Add HyperBus Controller node Add DT node for HyperBus Memory Controller in the FSS. On J721e, its not possible to use OSPI0 and HBMC simultaneously as they are muxed within the Flash Subsystem hence disable HBMC by default as keep OSPI enabled. Bootloader will fixup DT when it detects HyperFlash instead of OSPI. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Reviewed-by: Stefan Roese <sr@denx.de>
