- SCMI
- MHUv2
Currently, the main difference between TC0 (TARGET_PLATFORM=0) and TC1
(TARGET_PLATFORM=1) platforms w.r.t to TF-A is the CPUs supported. TC0 has
support for Cortex A510, Cortex A710 and Cortex X2, while TC1 has support for
Cortex A510, Cortex Makalu and Cortex Makalu ELP Arm CPUs.
Currently, the main difference between TC0 (TARGET_PLATFORM=0), TC1
(TARGET_PLATFORM=1), TC2 (TARGET_PLATFORM=2) platforms w.r.t to TF-A
is the CPUs supported as below:
- TC0 has support for Cortex A510, Cortex A710 and Cortex X2.
- TC1 has support for Cortex A510, Cortex Makalu and Cortex Makalu ELP.
- TC2 has support for Hayes and Hunter Arm CPUs.
