X-Received-From: 2607:f8b0:4864:20::642 Subject: [Qemu-devel] [PATCH for-3.2] RISC-V: Deprecate hifive_e and hifive_u machines X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Palmer Dabbelt , qemu-devel@nongnu.org Errors-To: qemu-devel-bounces+incoming=patchwork.ozlabs.org@nongnu.org Sender: "Qemu-devel" These machines had names that were too general: there are many E and U machines, and it's easy for users to get confused about which one is which. The one configuration that can faithfully match an existing ASIC-based board has been renamed to 'sifive-hifive1', we'll work through the emulation fidelity issues apparent in the other targets before adding machines for those.
