According to serial_class_init(), TYPE_SERIAL is an internal class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's move the latter into its own module which makes the dependencies more obvious and the code more tidy. The includes and the dependencies have been converted mechanically except in the hw/char directories which were updated manually. The result was compile-tested. Now, only hw/char makes direct use of TYPE_SERIAL: # grep -r -e "select SERIAL" | grep -v SERIAL_ hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL # grep -r -e "/serial\\.h" include/hw/char/serial-mm.h:#include "hw/char/serial.h" hw/char/serial-pci-multi.c:#include "hw/char/serial.h" hw/char/serial.c:#include "hw/char/serial.h" hw/char/serial-isa.c:#include "hw/char/serial.h" hw/char/serial-pci.c:#include "hw/char/serial.h" Tested-by: Andrew Jeffery Reviewed-by: Mark Cave-Ayland Signed-off-by: Bernhard Beschow --- include/hw/arm/aspeed_soc.h | 2 +- include/hw/char/mchp_pfsoc_mmuart.h | 2 +- include/hw/char/serial-mm.h | 52 +++++++++ include/hw/char/serial.h | 19 ---- hw/arm/allwinner-a10.c | 2 +- hw/arm/allwinner-h3.c | 2 +- hw/arm/allwinner-r40.c | 2 +- hw/arm/aspeed_ast2400.c | 2 +- hw/arm/aspeed_soc_common.c | 2 +- hw/arm/kzm.c | 2 +- hw/arm/msf2-soc.c | 2 +- hw/arm/musicpal.c | 2 +- hw/arm/npcm7xx.c | 2 +- hw/arm/pxa2xx.c | 2 +- hw/char/omap_uart.c | 2 +- hw/char/serial-mm.c | 157 ++++++++++++++++++++++++++++ hw/char/serial.c | 126 ---------------------- hw/display/sm501.c | 2 +- hw/hppa/machine.c | 2 +- hw/loongarch/virt.c | 2 +- hw/microblaze/petalogix_ml605_mmu.c | 2 +- hw/mips/boston.c | 2 +- hw/mips/jazz.c | 2 +- hw/mips/loongson3_virt.c | 2 +- hw/mips/malta.c | 2 +- hw/mips/mipssim.c | 2 +- hw/openrisc/openrisc_sim.c | 2 +- hw/openrisc/virt.c | 2 +- hw/ppc/e500.c | 2 +- hw/ppc/ppc405_uc.c | 2 +- hw/ppc/ppc440_bamboo.c | 2 +- hw/ppc/sam460ex.c | 2 +- hw/ppc/virtex_ml507.c | 2 +- hw/riscv/virt.c | 2 +- hw/sparc64/niagara.c | 2 +- hw/sparc64/sun4u.c | 2 +- hw/xtensa/xtfpga.c | 2 +- hw/arm/Kconfig | 20 ++-- hw/char/Kconfig | 4 + hw/char/meson.build | 1 + hw/display/Kconfig | 2 +- hw/hppa/Kconfig | 2 +- hw/loongarch/Kconfig | 2 +- hw/microblaze/Kconfig | 2 +- hw/mips/Kconfig | 10 +- hw/openrisc/Kconfig | 4 +- hw/ppc/Kconfig | 10 +- hw/riscv/Kconfig | 2 +- hw/sparc64/Kconfig | 1 + hw/xtensa/Kconfig | 2 +- 50 files changed, 276 insertions(+), 206 deletions(-) create mode 100644 include/hw/char/serial-mm.h create mode 100644 hw/char/serial-mm.c diff --git a/include/hw/arm/aspeed_soc.h b/include/hw/arm/aspeed_soc.h index 624d489e0d..689f52dae8 100644 --- a/include/hw/arm/aspeed_soc.h +++ b/include/hw/arm/aspeed_soc.h @@ -39,7 +39,7 @@ #include "hw/misc/unimp.h" #include "hw/misc/aspeed_peci.h" #include "hw/fsi/aspeed_apb2opb.h" -#include "hw/char/serial.h" +#include "hw/char/serial-mm.h" #include "hw/intc/arm_gicv3.h" #define ASPEED_SPIS_NUM 2 diff --git a/include/hw/char/mchp_pfsoc_mmuart.h b/include/hw/char/mchp_pfsoc_mmuart.h index b0e14ca355..a7b8b1b08b 100644 --- a/include/hw/char/mchp_pfsoc_mmuart.h +++ b/include/hw/char/mchp_pfsoc_mmuart.h @@ -29,7 +29,7 @@ #define HW_MCHP_PFSOC_MMUART_H #include "hw/sysbus.h" -#include "hw/char/serial.h" +#include "hw/char/serial-mm.h" #define MCHP_PFSOC_MMUART_REG_COUNT 13 diff --git a/include/hw/char/serial-mm.h b/include/hw/char/serial-mm.h new file mode 100644 index 0000000000..62a8489d69 --- /dev/null +++ b/include/hw/char/serial-mm.h @@ -0,0 +1,52 @@ +/* + * QEMU 16550A UART emulation + * + * Copyright (c) 2003-2004 Fabrice Bellard + * Copyright (c) 2008 Citrix Systems, Inc. + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in + * all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
