Author: marcel Date: Tue May 21 03:05:49 2013 New Revision: 250840 URL: http://svnweb.freebsd.org/changeset/base/250840 Log: Add basic support for FDT to i386 & amd64. This change includes: 1. 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. Obtained from: Juniper Networks, Inc.
