Subject: [PATCH] target/arm: Init GIC CPU IF regs for A15/A7
Date: Sat, 30 May 2020 01:06:53 +0200	[thread overview]
Message-ID: <20200529230653.GD776951@os.inf.tu-dresden.de> (raw)

Initialize the CPU interface registers also
for Cortex-A15 and Cortex-A7 CPU models, in
the same way as done for 64bit CPU models.
This fixes usage of GICv3 in virtualization
contexts in 32bit configurations.
