Subject: [PULL 04/38] ppc: Drop support for POWER9 and POWER10 DD1 chips
Date: Wed, 13 Mar 2024 02:58:15 +1000	[thread overview]
Message-ID: <20240312165851.2240242-5-npiggin@gmail.com> (raw)
In-Reply-To: <20240312165851.2240242-1-npiggin@gmail.com>

The POWER9 DD1 and POWER10 DD1 chips are not public and are no longer of
any use in QEMU. Remove them.
