At the moment isa-bus.c is compiled unconditionally for all targets. However, some targets have never used legacy ISA devices. Many more targets have at least some machine types without ISA. These patches allow ISA bus to be disabled in the configuration, thus allowing cut down configurations for targets and machine types that don't have ISA. Actually turning off ISA will require more than this for most targets - there are a number of non-obvious dependencies on the ISA code. b19c1c0 "isa: remove isa_mem_base variable" already got rid of an important one (VGA depended on ISA). Patches 2/4 and 4/4 in this series remove some more. There are a number more though, for example CONFIG_IDE_CORE depends on ISA and the HMP "info irq" command depends on I8259 code. But, these patches patch should allow easier experimentation so we can chip away at those dependencies on legacy code in the future. Changes in v3: * Added comment to pci.mak about why it enables ISA Changes in v2: * Removed changes to HMP, since it would cause a regression for PReP * Added a cleanup of the dead CONFIG_ISA_MMIO variable * Clearer explanation of the situation in commit messages David Gibson (4): Cleanup leftover CONFIG_ISA_MMIO Split serial-isa into its own config option Allow ISA bus to be configured out Split ISA and sysbus versions of m48t59 device default-configs/alpha-softmmu.mak | 1 + default-configs/arm-softmmu.mak | 2 +- default-configs/i386-softmmu.mak | 1 + default-configs/mips-softmmu.mak | 1 + default-configs/mips64-softmmu.mak | 1 + default-configs/mips64el-softmmu.mak | 1 + default-configs/mipsel-softmmu.mak | 1 + default-configs/moxie-softmmu.mak | 1 + default-configs/pci.mak | 2 + default-configs/ppc-softmmu.mak | 2 +- default-configs/ppc64-softmmu.mak | 2 +- default-configs/ppcemb-softmmu.mak | 1 + default-configs/sh4-softmmu.mak | 1 + default-configs/sh4eb-softmmu.mak | 1 + default-configs/sparc-softmmu.mak | 1 + default-configs/sparc64-softmmu.mak | 2 +- default-configs/unicore32-softmmu.mak | 1 + default-configs/x86_64-softmmu.mak | 1 + hw/char/Makefile.objs | 3 +- hw/isa/Makefile.objs | 2 +- hw/timer/Makefile.objs | 3 + hw/timer/m48t59-internal.h | 82 ++++++++++++ hw/timer/m48t59-isa.c | 180 +++++++++++++++++++++++++++ hw/timer/m48t59.c | 228 +++------------------------------- 24 files changed, 305 insertions(+), 216 deletions(-) create mode 100644 hw/timer/m48t59-internal.h create mode 100644 hw/timer/m48t59-isa.c -- 2.5.0
