Hi Paul!

Thanks for your interested in our Sourcery G++ Coldfire toolchains.

1. Are you running the assembler directly or through GCC?
2. Which version of the toolchain are you using? (m68k-elf-gcc --version)

The compiler does not accept -mcpu=5282, it only accepts 528x.
The assembler accepts -mcpu=5282.

Ufnortuantely the output of "m68k-elf-gcc --target-help" is sometimes
confusing since it includes help information for the assembler.

The 5281, 5282, 5283 are the same as 528x. I will file an internal issue
so that the compiler and assembler have similar options.

Cheers,
Carlos.
