Hi Simon, Magnus,
This patch series enables SMP support on the R-Car V3M SoC, by adding
the second Cortex-A53 CPU core. It also adds the performance monitor
unit, and links it to both CPU cores.
Changes compared to v1:
- Adjust GIC_CPU_MASK_SIMPLE(),
- Use symbolic core clock and power domain indices,
- Move the pmu node from the soc subnode to the root node, as it
doesn't have registers.
Note that the PSCI implementation on Eagle may be a preliminary version
with some familiar quirks:
- SMP bringup works, and both CPUs can be used,
- Offlining CPU0 crashes the system,
- CPU1 can be offlined, but trying to bring it online again crashes
the system, too.
I'm confident these will be fixed in future firmware versions, just like
on H3/Salvator-X. Note that
git@github.com:renesas-rcar/arm-trusted-firmware.git does not have
support for R-Car V3M, V3H, and D3.
Thanks!
