commit 8d9eb0d6d59a5d7028c80a30831143d3e75515a7 upstream.
qfprom has different address spaces for read and write. Reads are always done from corrected address space, where as writes are done on raw address space. Writing to corrected address space is invalid and ignored, so it does not make sense to have this support in the driver which only supports corrected address space regions at the moment.
