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
