Hi All,
I want suggestion on, How to boot multicore CPU from u-boot?
Modern SoC contain dual or qaud core same CPU core.Heterogeneous SoC contain ARM cortexAx+M3/4 or CortexAx+Renesas SH4 and many other combination.
As of now,I have two code to boot muticore CPU.
1)OMAP5 based SOC(DRA7 Dual core CortexA15) boot into AMP mode.Core0 boot u-boot and linux kernel.Core0 load RTOS/Baremetal to Core1 and start Core1.
2)Renesas R-CAR E2(CortexA7+SH4).Core0(CortexA7) boot u-boot and linux kernel.Core0(CortexA7) load RTOS to Core1(SH4) and start Core1(SH4).
Can we have common code or generic framework to boot other core from u-boot?
I have created framework for same but before submit it,I want your expert suggestion.
Similarly common framework to boot CPU in hypervisor mode.(I will disscuss in separate thread)
