From 26e8bed611222c4e2b9408a8d5a405158e491a98 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Fri, 17 Dec 2021 17:57:17 +0100 Subject: [PATCH] ppc: Mark the 'taihu' machine as deprecated MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The PPC 405 CPU is a system-on-a-chip, so all 405 machines are very similar, except for some external periphery. However, the periphery of the 'taihu' machine is hardly emulated at all (e.g. neither the LCD nor the USB part had been implemented), so there is not much value added by this board. The users can use the 'ref405ep' machine to test their PPC405 code instead.
