Re: [PATCH v5 0/5] Power11 support for QEMU [PSeries]

[Aditya Gupta]

Hello Nick & Cedric,

Based on your comments on considering the pseries for 9.1, and having to 
wait for skiboot parts for powernv, I have split the patch series into 
pseries and powernv.

There might be little delay in posting the powernv part, where I am 
still looking into having power11's instance_init.

Also, I have applied Harsh's patch that should simplify the rest of the 
patches.


Thanks,

Aditya Gupta
