[MIPS] Change PCI host bridge setup/resources

PCI host bridge setup for SNI RM machines with PCI is quite broken, now
that Linux does it's resource setup own its own. It will use IO addresses,
which are needed by the EISA config detection and assigns PCI memory
addresses, which overlap with ISA legacy addresses (video ram). Below
is a patch, which changes the way how the PCI memory addresses are
used and sets the minimum IO address to give enough IO space for
8 EISA slots). This patch needs the other PCI resource change, I've
posted.

Thomas Bogendoerfer [Sun, 8 Apr 2007 11:28:44 +0000]
[MIPS] Register PCI host bridge resource earlier

PCI based SNI RM machines have their EISA bus behind an Intel PCI/EISA
bridge. So the PCI IO range must start at 0x0000. Changing that will
break the PCI bus, because i8259.c already has registered it's IO
addresses before the PCI bus gets initialized. Below is a patch,
which will register the PCI host bridge resources inside
register_pci_controller(). It also changes i8259.c to use insert_region(),
because request_resource() will fail, if the IO space of the PIT hanging
of the PCI host bridge (maybe passing the resource parent to
init_i8259_irqs() is a cleaner fix for that).

[AVR32] Reserve framebuffer memory in early_parse_fbmem()

With the current strategy of using the bootmem allocator to allocate
or reserve framebuffer memory, there's a slight chance that the
requested area has been taken by the boot allocator bitmap before we
get around to reserving it.

By inserting the framebuffer region as a reserved region as early as
possible, we improve our chances for success and we make the region
visible as a reserved region in dmesg and /proc/iomem without any

Fix the I/O access macros so that they work with externally connected

* Use a set of macros to define I/O port- and memory operations

* Implement at32ap-specific port mangling (with build-time
