Hi,

1)  I have a total of four memories: RAM, Flash, DDR and Shared. I initialised the flash and ram like the follows: 

 MemoryRegion *flash = g_new(MemoryRegion, 1);
  int flash_size = board->flash_size_kb * 1024;
  memory_region_init_ram(flash, NULL, "machine.flash", flash_size, &error_fatal);
  memory_region_add_subregion(system_memory, FLASH_LOCATION, flash);

same for the ram and others. Later sum-up all and give it to the setupMemory. Is it the right way to define the total system memory.

I tried to follow this https://github.com/qemu/qemu/blob/stable-4.2/docs/devel/memory.rst but I'm confused or don't know which to use .

2)  How do we test a machine in qemu. I tried to put my machine files(.c and .h) into the test any used "make check" it gave error like this 

"qemu-4.2.0/target/arm/kvm-consts.h:17:8: error: attempt to use poisoned "CONFIG_KVM"

 #ifdef CONFIG_KVM
        ^ "

I understood the qtest for devices but machine how do we test?
