Thanks a lot! Julien,  now I can see console messages when booting domU.

I noticed that you have changed the gic mmio address to 0x10481000.
I figured that this gic (actually vgic) is emulated by
"xen/arch/arm/vgic.c" and according to the source code,
the virtual mmio address is defined as following:

    #define VGIC_DISTR_BASE_ADDRESS (GIC_BASE_ADDRESS+GIC_DR_OFFSET)

which is the same physical gic mmio address (plus GIC_DR_OFFSET).
So we have to use this (0x10481000) value, right?


Sincerely,
Thomas
