Previously, tsi148_master_set() assumed the address contained in its
PCI bus resource represented the actual PCI bus address. This is a fine
assumption on some platforms. However, on platforms that don't use a
1:1 (CPU:PCI) mapping this results in the tsi148 driver configuring an
invalid master window translation.

This patch updates the vme_tsi148 driver to first convert the address
contained in the PCI bus resource into a PCI bus address before using
it.

This patch corrects a typo where "vme_base" was used instead of
"*vme_base". The typo resulted in an incorrect value being returned
to userspace (via vme_user).

It also removes the following compile warning on some platforms:

warning: cast from pointer to integer of different size

The ca91cx42 and tsi148 VME bridges use the width of reads and writes on the
PCI bus in part to control the width of the cycles on the VME bus. It is
important that we can control the width of cycles on the VME bus as some VME
hardware requires cycles of a specific width. The memcpy_toio() and
memcpy_fromio() functions do not provide sufficient control, so instead loop
using ioread functions.

In order to ensure the correct width cycles on the VME bus, the VME bridge
drivers implement an algorithm to utilise the largest possible width reads and
writes whilst maintaining natural alignment constraints. The algorithm
currently looks at the start address rather than the current read/write address
when determining whether a 16-bit width cycle is required to get to 32-bit
alignment.  This results in incorrect alignment,

The tsi148 driver can be configured to reserve a window for internal
use (as part of the error checking routine). The intialisation of this
window currently configures a set of attributes that are never used
as these are only ever used by the VME core and this window is not
advertised to the core.

The TSI148 driver provides an optional mechanism for ensuring that errors
resulting from posted transfers are caught whilst still relevant. To do this
errors are stored in a link list. If bus errors are not checked, this list
would grow until available memory had been exhausted.

Only store the errors in a link list if error detection is switched on.

The memcpy_fromio() and memcpy_toio() functions use the __memcpy() function,
at least on x86. This function carries out transfers smaller than 32 bits as
multiple 8 bit transfers, causing a single (aligned) 16 bit transfer to be
split into 2 8 bit transfers which may not be supported by the target VME
device.

The commit 53059aa0 fixed this for the
ca91cx42, however this was not fixed for the tsi148 at the time. This patch
uses the same algorithm to fix the tsi148.
