The Meerkat96 board, based on the NXP i.MX7D SoC, is a member of
96Boards community and complies with all Consumer Edition board
specifications.
https://www.novtech.com/products/meerkat96.htmlhttps://www.96boards.org/product/imx7-96/
The initial supported/tested devices include:
- Debug serial
- SD
- USB Host (with Ethernet)
With these support, it's good enough for loading Linux Kernel from SD or
Ethernet over USB.

Add support to boot the MCU domain R5F Core0 remoteproc at U-boot prompt
on the AM65x EVM boards by using the 'boot_rprocs' and other env variables
defined in the common environment file k3_rproc.h, and updating the
'DEFAULT_RPROCS' macro.
The default configuration is to use the MCU R5F in Split mode, so both
the R5F Core0 and Core1 are started before loading and booting the Linux
kernel using the following firmware:
MCU R5FSS0 Core0 (Split) : 0 /lib/firmware/am65x-mcu-r5f0_0-fw
MCU R5FSS0 Core1 (Split) : 1 /lib/firmware/am65x-mcu-r5f0_1-fw
The MCU R5FSS was initially running the R5 SPL in LockStep mode with ATCM
disabled, and is actually shutdown to enable it to be reconfigured and
booted by either A53 U-Boot or Linux kernel in remoteproc mode and using
ATCM.
The MCU R5FSS would need to be reconfigured for Lockstep mode through
DT if a fault-tolerant/safety application were to be run on the cluster
with the DEFAULT_RPROCS macro updated to remove the Core1 firmware.

Add support to boot some remoteprocs at U-boot prompt on the J721E EVM
boards by using the 'boot_rprocs' and other env variables defined in the
common environment file k3_rproc.h, and updating the 'DEFAULT_RPROCS'
macro.
The list of R5F cores to be started before loading and booting the Linux
kernel are as follows, and in this order:
Main R5FSS0 (Split) Core1 : 3 /lib/firmware/j7-main-r5f0_1-fw
Main R5FSS1 (LockStep) : 4 /lib/firmware/j7-main-r5f1_0-fw
The MCU R5FSS0 and Main R5FSS1 are currently in LockStep mode, so the
equivalent Core1 rprocs (rproc #1 and #5) are not included. The Main
R5FSS0 Core0 (rproc #2) is already started by R5 SPL, so is not included
in the list either.
The DSP cores are started in the following order before loading and
booting the Linux kernel:
C66_0: 6 /lib/firmware/j7-c66_0-fw
C66_1: 7 /lib/firmware/j7-c66_1-fw
C71_0: 8 /lib/firmware/j7-c71_0-fw
The order of the rprocs to boot can be changed at runtime if desired by
overwriting the 'rproc_fw_binaries' environment variable at U-boot prompt.

Add a new file include/environment/ti/k3_rproc.h that defines
common environment variables useful for booting various remote
processors from U-Boot. This file is expected to be included in
the board config files with the EXTRA_ENV_RPROC_SETTINGS added
to CONFIG_EXTRA_ENV_SETTINGS and DEFAULT_RPROCS macro overwritten
to include the actual list of processors to be booted.
The 'boot_rprocs' variable just needs to be added to the board's
bootcmd to automatically boot the processors, and runtime control
can be achieved through the 'dorprocboot' variable.
The variables are currently defined to use MMC as the boot media,
and can be expanded in the future to include other boot media.
The immediate usage is intended for K3 J721E SoCs.

U-Boot binary has grown in such a way that it goes beyond the reserved
area for the environment variables.
Running "saveenv" causes U-Boot to hang because of this overlap.
Fix this problem by increasing the CONFIG_ENV_OFFSET size.
Also, in order to prevent this same problem in the future, use
CONFIG_BOARD_SIZE_LIMIT, which will detect the overlap in build-time.
CONFIG_BOARD_SIZE_LIMIT does not accept math expressions, so declare
CONFIG_ENV_OFFSET with its direct value instead.
