Bernhard, 

How did you adapt the templet files so they could compile under gcc?
Specifically the assembly files. I'm trying to use the modified templet
files provided by Arrow for their M5282ARB board, but the assembler 
gives errors like;

mcf5xxx.S:72: Error: operands mismatch -- statement `move.l sp,al' ignored

Also what goes the -r option mean in 

m68k-elf-gcc -r -o mcf5xxx.o mcf5xxx.s

Thanks for any help.

I didn't used that file for the 5282 pre-bootloader. I adopted
boot.S from the 5272 pre-bootloader, instead.

"-o" would add startfiles and libc (which is
certainly not what you want in this context),
so you need to add "-r" to prevent that.

it's "a1"(a-one) or "al", do you have typing mistake

"-r(elocation)" means object file mcf5xxx.o will be able to be relocated
