Alison,
Does Ryan have your 32-bit kernel image? I think kernel 32-bit doesn't support spin table. Please work with Ryan if your PSCI patch is required for the test.

Hi York/Alison,
Sorry for not having had time to look at this earlier.

To support loading a 32-bit OS, the execution state will change from AArch64 to AArch32 when jumping to kernel.
The architecture information will be got through checking FIT image, then U-Boot will load 32-bit OS or 64-bit OS automatically.

Changes in v7:
- Move the call for armv8_switch_to_el2_m into this patch.
Reviewers,
May I have your comment please? I intend to merge this set when the merge window opens.
I've just tested these two patches on ARM's FVP Foundation and AEMv8 models and ARM's Juno board.
In all cases, with this patchset, the kernel fails to start. I see a continuous reboot, where the kernel starts then immediately resets:
-------------------------------------------------- Starting kernel ...
resetting ... --------------------------------------------------
So I wouldn't want to see these patches merged.
Regards, Ryan.
