When converting lines like : - cpu_register_physical_memory_offset(0x1f800000, 0x1000, - sh7750_io_memory, 0x1f800000); - cpu_register_physical_memory_offset(0xff800000, 0x1000, - sh7750_io_memory, 0x1f800000);
I'm tempted to do : + memory_region_init_alias(&s->iomem_1f8, "memory-1f8", + &s->iomem, 0x1f800000, 0x1000); + memory_region_add_subregion(sysmem, 0x1f800000, &s->iomem_1f8); + + memory_region_init_alias(&s->iomem_ff8, "memory-ff8", + &s->iomem, 0xff800000, 0x1000); + memory_region_add_subregion(sysmem, 0xff800000, &s->iomem_ff8); but I'm affraid to loose some information contained in the offset different from the base address (0xff800000 != 0x1f800000). What is the current recommendation regarding such conversions ?
