On Octal DTR capable flashes like Micron Xcella the writes cannot start or end at an odd address in Octal DTR mode. Extra 0xff bytes need to be appended or prepended to make sure the start address and end address are even. 0xff is used because on NOR flashes a program operation can only flip bits from 1 to 0, not the other way round. 0 to 1 flip needs to happen via erases.
