+UART:
+-----
+ROM supports booting from MCU_UART0 via X-Modem protocol. The entire UART-based
+boot process up to U-Boot (proper) prompt goes through different stages and uses
+different UART peripherals as follows:

+R5 SPL | tispl.bin | MAIN_UART0 | Y-Modem
+A53 SPL | u-boot.img | MAIN_UART0 | Y-Modem

+(*) Note that in addition to X/Y-Modem related protocol timeouts the DMSC
+ watchdog timeout of 3min (typ.) needs to be observed until System Firmware
+ is fully loaded (from sysfw.itb) and started.

+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:
