...
This fixes up all of the smaller arches that had __dev* markings for
their platform-specific drivers.
CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Get rid of an unused variable in pcibios_fixup_device_resources() which leads
to the following warning:
arch/mn10300/unit-asb2305/pci.c: In function 'pcibios_fixup_device_resources':
arch/mn10300/unit-asb2305/pci.c:324:24: warning: unused variable 'region' [-Wunused-variable]
Whilst we're at it, merge the two integer variable declarations into one line.

Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus
resource fixups. This fixes the problem of "early" and "header" quirks
seeing incorrect root bus resources.

No functional change; this converts loops that iterate from 0 to
PCI_BUS_NUM_RESOURCES through pci_bus resource[] table to use the
pci_bus_for_each_resource() iterator instead.
This doesn't change the way resources are stored; it merely removes
dependencies on the fact that they're in a table.

Insert PCI root bus resources for the MN10300-based ASB2305 development
kit motherboard. This is required because the CPU's window onto the PCI
bus address space is considerably smaller than the CPU's full address
space and non-PCI devices lie outside of the PCI window that we might want
to access.
Without this patch, the PCI root bus uses the platform-level bus
resources, and these are then confined to the PCI window, thus making
platform_device_add() reject devices outside of this window.
We also add a reservation for the PCI SRAM region.

Use the generic pci_enable_resources() instead of the arch-specific code.
Unlike this arch-specific code, the generic version:
- checks PCI_NUM_RESOURCES (11), not 6, resources
- skips resources that have neither IORESOURCE_IO nor IORESOURCE_MEM set
- skips ROM resources unless IORESOURCE_ROM_ENABLE is set
- checks for resource collisions with "!r->parent"

Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.
This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305. The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.
