Building with CONFIG_INTEL_ACPIGEN fails on qemu-x86_64_defconfig

[Heinrich Schuchardt]

Hello Simon,

I wanted to look at ACPI tables using the acpi command on
qemu-x86_64_defconfig.

CONFIG_CMD_ACPI=y leads to build failure without CONFIG_ACPIGEN=y.

With both enabled no ACPI table is generated. Shouldn't there at least
be a board description?

If I additionally add CONFIG_INTEL_ACPIGEN=y, I end up with bunches of
errors. Isn't the emulated CPU an Intel one?

No clue why Chrome OS stuff is coming up: Chrome OS runs on different
platforms and not all Intel systems run Chrome OS.
