Tsirkin" , Kevin Wolf , Max Reitz , Paolo Bonzini , Richard Henderson , Eduardo Habkost , Peter Maydell , Kirill Batuzov The patch moves "hw/ide/achi.h", "hw/ide/pci.h" and "hw/ide/internal.h" headers to corresponding folders inside "include" folder alike other Qemu headers. Signed-off-by: Efimov Vasily --- This patch only moves headers (with the exception of include path correction in 'ahci.c'). checkpatch.pl reports a lot of problems with legacy code in these headers but I think this patch is not the place to fix these problem --- hw/ide/ahci.c | 2 +- hw/ide/ahci.h | 405 ----------------------------- hw/ide/internal.h | 635 ---------------------------------------------- hw/ide/pci.h | 76 ------ include/hw/ide/ahci.h | 405 +++++++++++++++++++++++++++++ include/hw/ide/internal.h | 635 ++++++++++++++++++++++++++++++++++++++++++++++ include/hw/ide/pci.h | 76 ++++++ 7 files changed, 1117 insertions(+), 1117 deletions(-) delete mode 100644 hw/ide/ahci.h delete mode 100644 hw/ide/internal.h delete mode 100644 hw/ide/pci.h create mode 100644 include/hw/ide/ahci.h create mode 100644 include/hw/ide/internal.h create mode 100644 include/hw/ide/pci.h diff --git a/hw/ide/ahci.c b/hw/ide/ahci.c index 502d4f1..b1a7b65 100644 --- a/hw/ide/ahci.c +++ b/hw/ide/ahci.c @@ -30,7 +30,7 @@ #include "qemu/error-report.h" #include "sysemu/block-backend.h" #include "sysemu/dma.h" -#include "internal.h" +#include #include #include diff --git a/hw/ide/ahci.h b/hw/ide/ahci.h deleted file mode 100644 index bc777ed..0000000 --- a/hw/ide/ahci.h +++ /dev/null @@ -1,405 +0,0 @@ -/* - * QEMU AHCI Emulation - * - * Copyright (c) 2010 qiaochong@loongson.cn - * Copyright (c) 2010 Roland Elek - * Copyright (c) 2010 Sebastian Herbszt - * Copyright (c) 2010 Alexander Graf - * - * This library is free software; you can redistribute it and/or - * modify it under the terms of the GNU Lesser General Public - * License as published by the Free Software Foundation; either - * version 2 of the License, or (at your option) any later version. - * - * This library is distributed in the hope that it will be useful, - * but WITHOUT ANY WARRANTY; without even the implied warranty of - * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
