yes it was added to 3.15-rc1. Try to rever this one a66a626 microblaze: Use asm-generic/io.h but the problem is probably here because you are not getting proper reaction from qemu model. a1715bb microblaze: Make timer driver endian aware 1aa1243 microblaze: Make intc driver endian aware I have tested it on the latest petalinux qemu and there shouldn't be any problem.
