[Qemu-devel] [PATCH v2 01/10] ppc: Update SPR definitions

[Cédric Le Goater]

From: Benjamin Herrenschmidt <address@hidden>

Add definitions for additional SPR numbers and SPR bit definitions
that will be relevant for subsequent improvements to POWER8 emulation

Also fix the definition of LPIDR which was incorrect (and is different
for server and embedded).
