Subject: [PATCH 1/3] target/ppc: Fix MPCxxx FPU interrupt address
Date: Wed,  8 Dec 2021 09:30:27 -0300	[thread overview]
Message-ID: <20211208123029.2052625-2-farosas@linux.ibm.com> (raw)
In-Reply-To: <20211208123029.2052625-1-farosas@linux.ibm.com>

The Floating-point Unavailable and Decrementer interrupts are being
registered at the same 0x900 address. The FPU should be at 0x800
instead.

Verified on MPC555, MPC860 and MPC885 user manuals.
