[PATCH 0/2] TI K3 R5F remoteproc support on AM46x SoCs

[Suman Anna]

Hi All,

The following series enhances the K3 R5F remoteproc driver to add support
for the R5F clusters on the newer TI K3 AM64x SoC family. The AM64x SoCs
have 2 R5FSS clusters and no DSPs. Both clusters are capable of supporting
either the conventional Split-mode or a brand new "Single-CPU" mode.

The revised R5FSS IP has the following unique features:
 1. The new Single-CPU mode allows the Core1 TCMs to be combined with
    the Core0 TCMs effectively doubling the amount of TCMs available.
    This is same behavior as LockStep-mode on J7200 SoCs, but all other
    previous SoCs could only use the Core0 TCMs. This combined TCMs appear
    contiguous at the respective Core0 TCM addresses.
 2. TCMs are auto-initialized during module power-up, and the behavior
    is programmable through a SEC_MMR register bit. This is same as on
    J7200 SoCs, and is not present on earlier AM65x and J721E SoCs.

The series is based on 5.12-rc2, and can apply on top of the current
rproc-next branch as well.

regards
Suman
