linux-yocto: bsp/beaglebone: support qemu -machine virt
While we don't normally do a dual h/w and virt BSP (since they
tend to have conflicting requirements over time). A minimal overhead
option to do this was submitted to linux-yocto. Since it has no
impact on the h/w reference, has SDK testing value and can serve
as a template on how to do this for other arm boards, it is worth
making the configuration available.
The original commit log follows:
[
If the kernel supports Qemu's virt machine, runqemu works almost for free.
The device tree for machine virt is included in Qemu, which simplifies
everything quite a bit.
This change adds ARCH_VIRT=y and some drivers to the beaglebone kernel
configuration which allows to:
This also works out of an eSDK. Whithout this feature usually two
different SDKs need to be compiled and maintained. One SDK is used for development
in Qemu, another one is used to develop for the real target hardware.
