I guess it would be extremely useful for u-boot. It is being used by q-boot, a new minimal x86 firmware for QEMU. http://lwn.net/Articles/645455/ https://github.com/bonzini/qboot q-boot is able to give a minimal booting time, with the help of fw_cfg, by reading both the kernel and initrd image from fw_cfg. I guess ACPI support for both q-boot and qemu-x86 in u-boot can be implemented on similar lines.
