TODO:
- I vaguely recall that one of the early platform we
supported add
the memory starting in high memory (> 1TB). I need to check
whether the new layout will be fine.
I think we have some Juno with some memory like that, tell me if you
need help here.
Would you be able to check the memory layout and confirm?
I checked and the Juno we have as the high memory a lot lower than that:
RAM: 0000000880000000 - 00000009ffffffff
No idea why it was a lot higher in my mind.
I have only encountered one board with the memory over 512GB. I can't
remember whether it is AMD Seattle or X-Gene.
So I found the answer. This was AMD Seattle where the memory start at
512GB. So I will map Xen starting at 2TB (so there is a bit of slack).
Cheers,
