[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
