Some ARM aarch64 Cortex-family processors only supports

config ARCH_SET_VMPIDR_EL2

bool "Set VMPIDR_EL2 at EL2 stage"
|

---help---
|
|
VMPIDR_EL2 holds the value of the Virtualization Multiprocessor ID.
|
|
From architecture manual of AArch64, the behave is:
|
|
-reading register MPIDR_EL1 in EL2, it's return real MPIDR_EL1
|
|
-reading register MPIDR_EL1 in EL1, it's return VMPIDR_EL2
|
|
So since NuttX for SMP is running at EL1 to read MPIDR_EL1 for
|
|
identify CPU id, it's need to set VMPIDR_EL2 to MPIDR_EL1 for
|
|
every CPU at boot EL2 stage.
|
|
For some platform, the bootloader or hypervisor will do that at
|
|
the EL2 stage, but not all.
|
|
ARM FVP and VDK should set it since these platform will boot
|
|
without BootLoader.

---help---
|

The aarch64 have EL0~El3 execute level and NS/S (security state),
|
|
the NuttX should be execute at EL1 in NS(ARmv8-A) or S(ARmv8-R)
|
|
state. but booting NuttX have different ELs and state while with
|
|
different platform, if NuttX runing at wrong ELs or state it will
|
|
not normal anymore. So we need to print something in arm64_head.S
|
|
to debug this situation.
|
|
Enabling this option will need to implement arm64_earlyprintinit and
|
|
arm64_lowputc functions just you see in qemu_lowputc.S.
|
|
by default, UART dev will be used. You can also logging the booting
|
|
message through rewriting fake arm64_lowputc with other debug
|
|
method (eg semihosting , ARM debug channel etc)
|
|
if you not sure, keeping the option disable.
