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.

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>

platform: add chrome platform directory It makes sense to split out the Chromebook/Chromebox hardware platform drivers to a separate subdirectory, since some of it will be shared between ARM and x86.

platform: Add Surface platform directory It may make sense to split the Microsoft Surface hardware platform drivers out to a separate subdirectory, since some of it may be shared between ARM and x86 in the future (regarding devices like the Surface Pro X). Further, newer Surface devices will require additional platform drivers for fundamental support (mostly regarding their embedded controller), which may also warrant this split from a size perspective. This commit introduces a new platform/surface subdirectory for the Surface device family, with subsequent commits moving existing Surface drivers over from platform/x86. A new MAINTAINERS entry is added for this directory. Patches to files in this directory will be taken up by the platform-drivers-x86 team (i.e. Hans de Goede and Mark Gross) after they have been reviewed by Maximilian Luz.

platform/x86: Kconfig: Remove unnecessary "if X86" drivers/platform/x86/Kconfig is wrapped in one big if X86_PLATFORM_DEVICES .. endif and X86_PLATFORM_DEVICES already has a "depends on X86" so the "if X86" in drivers/platform/Kconfig is not necessary and except for MIPS none of the other includes there has such an if. So let's remove it. While at it also move the x86/Kconfig include to the end of the file for alphabetical sorting.

platform: Add ARM64 platform directory Some ARM64 based laptops and computers require vendor/board specific drivers for their embedded controllers. Even though usually the most important functionality of those devices is implemented inside ACPI, unfortunately Linux doesn't currently have great support for ACPI on platforms like Qualcomm Snapdragon that are used in most ARM64 laptops today. Instead Linux relies on Device Tree for Qualcomm based devices and it's significantly easier to reimplement the EC functionality in a dedicated driver than to make use of ACPI code. This commit introduces a new platform/arm64 subdirectory to give a place to such drivers for EC-like devices. A new MAINTAINERS entry is added for this directory. Patches to files in this directory will be taken up by the platform-drivers-x86 team (i.e. Hans de Goede and Ilpo Järvinen) with additional review from Bryan O'Donoghue to represent ARM64 maintainers.

platform/raspberrypi: Destage VCHIQ interface Destage the VCHIQ interface driver to drivers/platform/raspberrypi. There is still the remaining TODO item of improving the documentation, which can be handled post destaging. Secondly, multimedia drivers like codec and ISP that rely on this interface need to be upstreamed. And lastly, the drivers that facilitate the shared memory between VideoCore and Linux, like the vc-sm-cma driver and vc_mem char driver also need to be upstreamed.
