From fcf5ef2ab52c621a4617ebbef36bf43b4003f4c0 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Tue, 11 Oct 2016 08:56:52 +0200 Subject: Move target-* CPU file into a target/ folder We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.
