Subject: mcf_intc: Pass M68kCPU to mcf_intc_init()
X-Git-Tag: Tizen_Studio_1.3_Release_p2.3.1~900^2~59^2~783^2~15
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9a6ee9fd35483446fe14e083fa335358c86ba595;p=sdk%2Femulator%2Fqemu.git

mcf_intc: Pass M68kCPU to mcf_intc_init()

Store it in mcf_intc_state.
Prepares for passing it to m68k_set_irq_level().
