5c16736a37 SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).
Main purpose of this is to delete
       *physical = address & 0x1fffffff;
at target-sh4/helper.c:449, using new mmio rule introduced by #5849
This masking is a nice trick to realize P4/A7 duality of SH registers.
But, IMHO, it is logically wrong.

Most of SH4 cpu control registers in P4 area(0xfc000000...0xffffffff) have
one more address called A7 which is usually P4 address with upper 3bits masked.
This is an address only appears in TLB's physical address part.

Current code use trick writing drivers as if they are really in A7
(that's why you see many *_A7 in hw/sh*.c), and using translation P4 to A7.

96e2fc41a9 SH4: Use qemu_irq in timer emulation.
* hw/sh.h (tmu012_init): Accept qemu_irq, not intc_source.
        * hw/sh7750.c (sh7750_init): Pass qemu_irq to tmu012_init.
        * hw/sh_intc.c (sh_intc_set_irq): New.
        (sh_intc_init): Allocate irqs.
        * hw/sh_intc.h (struct intc_desc): New field irqs.
        * hw/sh_timer.c (sh_timer_state): Use qemu_irq, not intc_source.
        (sh_timer_update): Use qemu_set_irq, not sh_intc_toggle_source.
        (sh_timer_init, tmu012_init): Adjust.
