Then in the linking stage define the location of the FPGA something like
this in Makefile:

LDFLAGS= -Wl,-Map,address@hidden \
        -Wl,--section-start=.eeprom=0x00810001 \
        -Wl,--section-start=.fpga1=0x6000 \
        -Wl,--section-start=.hsa2d=0x7000 \

Just use the __attribute__ to tag variables as section .sram and the
compiler will find places for them if you don't care about the order.

Oops, come to think of it "data-memory mapped" needs 0x800000 added as an offset so to indicate which memory space it belongs. Add 0x810000 for EEPROM as shown. Most of the above lands in FLASH code space.
