Hi Lokesh,
The following series cleans up the code related to booting of Main R5FSS0 Core0 from R5 SPL, and moves it to A72 U-Boot on J721E SoCs. This is no longer supported after the R5 SPL re-architecture that splits the System Firmware functionality onto two separate processors. This functionality has been merged post v2021.07 tag towards v2021.10-rc1. The Main R5FSS0 Core0 is already being booted on A72 U-Boot on J7200 SoCs, the other SoC family that follows this split system firmware architecture.
Following is the patch summary:
- Patch 1 skips the booting of Main R5FSS in R5 SPL and moves it to be supported on A72 U-Boot.
- Patches 2 and 3 cleanup the start_non_linux_remote_cores() code
- Patch 4 removes the Main R5F nodes from R5 SPL dtb
- Patch 5 disables the K3 R5F remoteproc driver to be built in R5 SPL (tiboot3.bin size reduces by about 5K).
Forgot to mention that patches are on top of your for-rc HEAD, commit cd096aa47423 ("configs: am335x_evm: Support GbE PHYs")
