pci-iomap.c was (apparently, mistakenly) reintroduced as part of
commit 83c2dc15ce824450e7044b9f90cd529c25747ae0
MN10300: Handle cacheable PCI regions in pci_iomap()
probably as side-effect of forward-porting the patch
from an old kernel.
It's not really needed: the generic pci_iomap does the right thing here.
The new file isn't compiled so it's safe to drop.

Handle cacheable PCI regions in pci_iomap(). If IORESOURCE_CACHEABLE is set
then we AND away the 0x20000000 "flag".

The pci_iomap variant that arch/mn10300/unit-asb2305/pci-iomap.c
uses differs from the generic one in that it does
not use ioremap_nocache for PCI addresses.
However, it turns out that PCI addresses are
automatically noncached, so switching to ioremap_nocache
and to the generic implementation is safe.

Almost all implementations of pci_iomap() in the kernel, including the generic
lib/iomap.c one, copies the content of a struct resource into unsigned long's
which will break on 32 bits platforms with 64 bits resources.
This fixes all definitions of pci_iomap() to use resource_size_t. I also
"fixed" the 64bits arch for consistency.

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.
