[Skiboot] [PATCH 01/22] xive: introduce header files for the registers
Cédric Le Goater
clg at kaod.org
Wed Sep 4 03:03:52 AEST 2019
This is moving the definitions of the registers of the P9 XIVE
interrupt controller and the P9 XIVE internal structures in a specific
header file and moving the definitions related to the thread interrupt
context area to a common file.
