ppc64: add e6500

[Qemu-devel] [PATCH for-2.11 0/4] ppc64: add e6500

Posted by KONRAD Frederic 6 years, 8 months ago

Hi,

Those are some patches to add basic e6500 support for the moment e5500 with a
correct MMU configuration and supported instructions.
Some (maybe a lot of) things are missing (ie: the thread support) but it is
enough to boot a propietary OS on my side.

The first two patches are fixes when using MAV 2.0 MMU.
The two last patches introduces the e6500.

This can be cloned here:
https://github.com/FredKonrad/qemu.git branch e6500

Thanks,
Fred

Looks sane as best as my minimal knowledge of e500 goes.  Applied to
ppc-for-2.11.  Alex, if you (or anyone with knowledge of this
platform) has objections, I'll reconsider.

I think it's good enough. We're missing a *lot* of e6500 features, but 
if this is useful to Frederic, I don't see a good reason to hold it back.
