Introduction:
-------------
The J721e family of SoCs are part of K3 Multicore SoC architecture platform
targeting automotive applications. They are designed as a low power, high
performance and highly integrated device architecture, adding significant
enhancement on processing power, graphics capability, video and imaging
processing, virtualization and coherent memory support.
The device is partitioned into three functional domains, each containing
specific processing cores and peripherals:
1. Wake-up (WKUP) domain:
- Device Management and Security Controller (DMSC)
2. Microcontroller (MCU) domain:
- Dual Core ARM Cortex-R5F processor
3. MAIN domain:
- Dual core 64-bit ARM Cortex-A72
- 2 x Dual cortex ARM Cortex-R5 subsystem
- 2 x C66x Digital signal processor sub system
- C71x Digital signal processor sub-system with MMA.
More info can be found in TRM: http://www.ti.com/lit/pdf/spruil1
Boot Flow:
----------
Boot flow is similar to that of AM65x SoC and extending it with remoteproc
support. Below is the pictorial representation of boot flow:

- Here DMSC acts as master and provides all the critical services. R5/A72
requests DMSC to get these services done as shown in the above diagram.
