boards/x86/acrn_ehl_crb: Enable SMP by default SMP is working now, make a 2-cpu configuration default for this device. Note that this requires changes to the default ACRN build configuration! In hybrid.xml, you need to specify multiple physical CPUs for the VM to uses, e.g.: <vm id="0"> ... <cpu_affinity> <pcpu_id>0</pcpu_id> <pcpu_id>1</pcpu_id> </cpu_affinity> </vm> Failing to build with this change will result in the system hanging at boot trying to start up a CPU that won't run.

boards/x86: add ACRN UOS sample board configuration Based on prior work by @dcpleung. It's suboptimal, but it provides a working starting point for ACRN work. The x86 board/SoC abstractions really need to be refactored to make this "board" (and other x86-based "boards", both extant and future) cleaner and easier to maintain. Punt. Signed-off-by: Charles E.

kconfig: Replace defconfig singe-symbol 'if's with 'depends on' Same deal as in commit eddd98f ("kconfig: Replace some single-symbol 'if's with 'depends on'"), for all symbols defined within defconfig files. See that commit for an explanation. Maybe 'if's were used originally to mirror the 'if's in the main Kconfig files, and then it got copied around by people assuming 'if' must work differently from 'depends on'. It doesn't match in every spot at least. Better to keep it simple and just consistently use 'depends on' when it's a single symbol/choice I think. Helps reinforce that 'if' isn't magic too. Verified by printing all Kconfig menu nodes (symbols, choices, menus, etc.) before and after the change and diffing (should show no difference).
