This is the setting in v2021.01 U-Boot and the dt nodes are synched with the kernel binding property names in commit 468ec2f3ef8f ("remoteproc: k3_r5: Sync to upstreamed kernel DT property names") merged in v2021.04-rc2. The modes for both the clusters got switched back to LockStep mode by mistake in commit 70e167495ab2 ("arm: dts: k3-j721e: Sync Linux v5.11-rc6 dts into U-Boot") also in v2021.04-rc2. This throws the following warning messages when early-booting the cores using default env variables, k3_r5f_rproc r5f at 5d00000: Invalid op: Trying to start secondary core 7 in lockstep mode Load Remote Processor 3 with data at addr=0x82000000 98484 bytes: Failed! k3_r5f_rproc r5f at 5f00000: Invalid op: Trying to start secondary core 9 in lockstep mode Load Remote Processor 5 with data at addr=0x82000000 98484 bytes: Failed! Fix this by switching back both the clusters to the expected Split-mode. Make this mode change in the u-boot specific dtsi file to avoid such sync overrides in the future until the kernel dts is also switched to Split-mode by default.
