Hi, Alex,
As there is strong objection to remove the codes about switching
to EL1, I think we have to remain it, do you agree?
If it is remained, I think your suggestion about *always*
jumping to ep for both switching to AArch64 and AArch32 modes will make the
code hard to realize and very complicated. So I prefer to keep the process in
v4 patches. What is your opinion?
Best Regards,
Alison Wang

As CONFIG_ARMV8_SWITCH_TO_EL1 is not used now, this patch is to remove
CONFIG_ARMV8_SWITCH_TO_EL1 and the corresponding functions.

I'll CC the maintainers for ZynqMP and Exynos as well, but from my side this
patch is a great step forward.

I am against this patch. The reason is simple. We are using this option for
testing to make sure that hyperviser and OS
behaves correctly when they start from different level.
Thanks,
Michal
