goldfish: refactor goldfish platform configs On new virtual devices, the goldfish virtual bus can be replaced with autoprobing infrastructure like Device Tree. Refactor the goldfish kernel configs to better accommodate this. Move the goldfish platform into a menuconfig in the style of the chrome platform, and separate the goldfish bus into its own config option.

menuconfig GOLDFISH
bool "Platform support for Goldfish virtual devices"
platform: goldfish: Allow goldfish drivers for archs with IOMEM and DMA We don't need explicit dependency of Goldfish kconfig option on various architectures. Instead, the Goldfish kconfig option should only depend on HAS_IOMEM and HAS_DMA which is sufficient for all Goldfish devices.

depends on HAS_IOMEM && HAS_DMA
platform: goldfish: move the separate 'default' propery for CONFIG_GOLDFISH Currently, there are two entries for CONFIG_GOLDFISH. In arch/x86/Kconfig: config GOLDFISH def_bool y depends on X86_GOLDFISH In drivers/platform/goldfish/Kconfig: menuconfig GOLDFISH bool "Platform support for Goldfish virtual devices" depends on HAS_IOMEM && HAS_DMA While Kconfig allows multiple entries, it generally leads to tricky code. Prior to commit bd2f348db503 ("goldfish: refactor goldfish platform configs"), CONFIG_GOLDFISH was an alias of CONFIG_X86_GOLDFISH. After the mentioned commit added the second entry with a user prompt, the former provides the 'default' property that is effective only when X86_GOLDFISH=y. Merge them tegether to clarify how it has worked in the past 8 years.

Say Y here to get to see options for the Goldfish virtual platform.
This option alone does not add any kernel code.
Unless you are building for the Android Goldfish emulator say N here.

goldfish: add QEMU pipe driver A QEMU pipe is a very fast communication channel between the guest system and the emulator. Usage from the guest is simply something like; // connect to special device fd = open("/dev/qemu_pipe", O_RDWR); // tell which service we want to talk to (must be zero-terminated) write(fd, "pipeName", strlen("pipeName")+1); // do read()/write() through fd now ... // close channel close(fd); Signed-off-by: David 'Digit' Turner <digit@android.com> [Added support for parameter buffers for speed] igned-off-by: Xin, Xiaohui <xiaohui.xin@intel.com> Signed-off-by: Jiang, Yunhong <yunhong.jiang@intel.com> Signed-off-by: Nakajima, Jun <jun.nakajima@intel.com> [Ported to 3.6] Signed-off-by: Tom Keel <thomas.keel@intel.com> [Ported to 3.7, moved to platform/goldfish] Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
