util/qemu: Revise q35 configs
Add an NVMe drive and be more conservative with hotplug-capable PCIe ports. QEMU treats everything as hotpluggable by default, so devices can be added at runtime. However, this leads to unrealistic resource allocations with PCIEXP_HOTPLUG enabled. Tested recent allocator changes with QEMU/Q35 config and: $ make qemu QEMU_EXTRA_CFGS=util/qemu/q35-alpine.cfg Change-Id: I23746b642329356c6767b04ec177cd9411e3adb9 Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: https://review.coreboot.org/c/coreboot/+/67026 Reviewed-by: Felix Singer <service+coreboot-gerrit@felixsinger.de> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Lean Sheng Tan <sheng.tan@9elements.com>
