Re: [Qemu-devel] [PATCH 0/6][RFC] AArch64 support for Versatile Express using KVM

["Mian M. Hamayun" <m.hamayun@virtualopensystems.com>]

At the time we started working on AArch64, we were not certain that our 
implementation would be published in near future. Now that this is 
cleared up we are more than happy to coordinate together.

Initially we thought about this aspect too, but in order to get started, 
we made the choice to continue using the already available A15 part as 
is. Obviously this is an RFC patch series and we would like to have your 
opinion on how we can proceed from here, based on the working solution 
that we have now, although we may have some differences from the real 
hardware.
