The GNU triplet for the carl9170 firmware toolchain

Hi,

Having been working on the same for ath9k_htc, I'm looking into making a 
Debian package for carl9170 so it gets built from source on Debian 
infrastructure. I'm trying to identify the ideal cross triplet to use for 
packaging the cross tools.

I see the toolchain Makefile builds Binutils and GCC with --target=sh-elf, but 
the README also specifies that an SH-2 toolchain is needed. Does sh-elf imply 
sh1-elf, and would it be preferable (or different) to use sh2-elf instead, or 
is it an alias for sh2-elf?

Debian already has sh4-* tools, so I'd like the parallelism of sh2-elf, but I 
wonder if this is a different ABI. config.sub seems equally happy to recognize 
either sh-elf or sh[1234]-elf.

Thanks,
John
