Write an assembly program for PIC18F87J94 which reads the content of a connected 25L1024 SPI EEPROM and writes it to the PIC's flash memory.

It's a bootloader like program which stays at the top of the PIC's flash memory. I fill up the external EEPROM in my project and call this function which reprograms the PIC's flash memory (e.g. firmware update). I can write it in mikroC but cannot relocate all the built in routines to the upper memory region.
