[IA64-SGI] pcdp: add PCDP pci interface support
Resend 2 with changes per Bjorn Helgaas comments. Changes from original: + Change globals to vga_console_iobase/vga_console_membase and make them unconditional. + Address style-related comments. Patch to extend the PCDP vga setup code to support PCI io/mem translations for the legacy vga ioport and ram spaces on architectures (e.g. altix) which need them. Summary of the changes: drivers/firmware/pcdp.c drivers/firmware/pcdp.h ----------------------- + add declaration for the spec-defined PCI interface struct (pcdp_if_pci) as well as support macros. + extend setup_vga_console() to know about pcdp_if_pci and add a couple of globals to hold the io and mem translation offsets if present. arch/ia64/kernel/setup.c ------------------------ + tweek early_console_setup() to allow multiple early console setup routines to be called. include/asm-ia64/vga.h ---------------------- + make VGA_MAP_MEM vga_console_membase aware Signed-off-by: Mark Maule <maule@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
