pre-calibration is meant for qca4019 which contains only caldata whereas calibration file is used by ar9888 and qca99x0 that contains both board data and caldata. So by definition both pre-cal-file and cal-file can not coexist. Keeping them in shared memory (union), is breaking boot sequence of qca99x0. Fix it by storing both binaries in separate memories. This issue is reported in ipq8064 platform which includes caldata in flash memory.
