The J2 Core is an open hardware cpu implementing the SH-2 instruction
set, with the addition of barrel shift instructions and an atomic
compare-and-swap instruction. This patch adds a cpu model option -mj2
to the sh target. Presently all it does is enable use of the barrel
shift instructions (and t
