Make 2 different projects for that.

Upload buffer at the start of flash address, 0x08000000, and bootloader to your desired offset location in flash. Don't forgot to set vector table offset to your main project.That's all. Search for IAP example from ST

Others just use the IAP examples as a starting point, and if necessary learn how GNU/GCC allows code placement using Linker Scripts (.LD), or how an IDE presents that in a menu/option format.
