Subject: [PATCH v5 6/9] target/riscv: tt-ascalon: Enable Svadu by removing Svade
Date: Thu,  7 May 2026 14:38:34 +1000	[thread overview]
Message-ID: <20260507043838.45652-7-npiggin@gmail.com> (raw)
In-Reply-To: <20260507043838.45652-1-npiggin@gmail.com>

Ascalon supports Svadu (hardware A/D bit updates).

QEMU makes Svadu and Svade mutually exclusive, remove Svade so
Ascalon comes up with Svadu working.
