[U-Boot] [PATCH 0/2] Disable K3_SYSTEM_CONTROLLER on K3 Arm64 cores
Hi Lokesh, Tom,
The K3 System Controller remoteproc driver is only needed on R5 SPL, and need not be enabled or built for the K3 Arm64 U-Boot/SPL targets. The following 2 patches are minor cleanup patches disabling the same for K3 Arm64 U-boot/SPL targets on both AM65x and J721E SoCs.
regards Suman

The K3 System Controller driver is used for loading and starting the System Firmware, and is used only on R5 SPL. It need not be enabled and built for the A53 U-Boot and SPL, so disable it from both the GP and HS AM65x A53 defconfigs.
While at this, also remove the unneeded CONFIG_SPL_REMOTEPROC and CONFIG_CMD_REMOTEPROC as no remoteprocs are now loaded from A53 SPL.

This is a result of using savedefconfig, I prefer it this way since it allows other developers adding options to do it cleanly. If and when a REMOTEPROC is enabled, the savedefconfig with corresponding options should automatically bring this back.

Indeed, if savedefconfig is taking it out, it's not being built today OR it's already default y and being built.

ohh okay. I didn't know it was a result of savedefconfig as you mentioned it is explicitly removed. Patch as such looks good to me.
