Devices whose interrupt-parent property points to a beripic device will have their interrupt allocation, activation, and setup operations routed through the IC rather than down the traditional bus hierarchy. This driver largely abstracts the underlying CPU away allowing the PIC to be implemented on CPU's other than BERI. Due to insufficient abstractions a small amount of MIPS specific code is currently required in fdt_mips.c and to implement counters.

The current implementation requires that device declarations have an interrupt-parent node and that it point to a device that has registered itself as a interrupt controller in fdt_ic_list_head and implements the fdt_ic interface.

Common headers for fdt.h and ofw_machdep.h under x86/include with indirections under i386/include and amd64/include. 2. New modinfo for loader provided FDT blob. 3. Common x86_init_fdt() called from hammer_time() on amd64 and init386() on i386. 4. Split-off FDT specific low-level console functions from FDT bus methods for the uart(4) driver. The low-level console logic has been moved to uart_cpu_fdt.c and is used for arm, mips & powerpc only. The FDT bus methods are shared across all architectures. 5. Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and the fdt_pic_table[] arrays. Both are empty right now. FDT addresses are I/O ports on x86. Since the core FDT code does not handle different address spaces, adding support for both I/O ports and memory addresses requires some thought and discussion. It may be better to use a compile-time option that controls this.
