Hi Lokesh,
The following series adds the support for the branch-only boot of an
application firmware on MCU R5F from R5 SPL after it has finished
launching the A72.
Most of the changes are just related to updating J7200 defconfigs or
dts nodes, as the core logic for R5 SPL branch-only boot is already
present. The boot media supported is _only_ SDCard just like with
J721E SoCs. Firmware images to be used are the non-ATCM images.
The series is on top of the previous "Early-boot support of R5FSS from
A72 U-Boot for J7200 SoCs" [1].
Following is the patch summary:
- Patch #1 updates the R5 SPL rproc env variables for J7200 SoCs given
the different firmware names used between J721E & J7200 SoCs. The
Main R5FSS variables are also left out, until the support for the
same is added to code.
- Patches #2 and #3 add and enable the FS_LOADER node and Kconfigs
regards
Suman

The R5 SPL on J7200 SoCs will be limited to booting just the
MCU R5FSS0 R5F core in LockStep-mode at present, so add the
two required environment variables 'addr_mcur5f0_0load' and
'name_mcur5f0_0fw' that are needed by the R5 SPL early-boot
logic. The firmware name used is also different from that on
J721E SoCs.

Add a generic fs_loader node to the K3 J7200 R5 common board dts
file and use it as the chosen firmware-loader so that it can be
used for loading various firmwares from a boot media/filesystem
in R5 SPL on K3 J7200 EVM.

Enable the FS_LOADER and associated configs in the j7200_evm_r5_defconfig
so that the R5 SPL can support the loading of firmware files from a boot
media/file system.

I realized I used underscore in the node name. Can you fix up the node name
while applying, or do you want me to send a v2?

Applied to u-boot-ti next branch.
