GPLv2 doesn't allow additional restrictions to be imposed on any
code, so this wording needs to be removed from these files.Signed-off-by: Stephen Neuendorffer

Both the buffer-based and fifo-based icap cores have a status
register. Previously, this was only used internally to check whether
transactions have completed. However, the status can be useful to the
main driver as well. This patch exposes these status functions to the
main driver along with some masks for the differnet bits.Signed-off-by: Stephen Neuendorffer

This fixes various items pointed out during a review of the hwicap driver.
Primarily, reversed memcpy calls, re-entrancy issues, and mutex conversion
have been addressed. There are also fixes to comments to use the kerneldoc
format, as well as some sparse annotations.Signed-off-by: Stephen Neuendorffer

This includes code for new fifo-based xps_hwicap in addition to the
older opb_hwicap, which has a significantly different interface. The
common code between the two drivers is largely shared.Significant differences exists between this driver and what is
supported in the EDK drivers. In particular, most of the
architecture-specific code for reconfiguring individual FPGA resources
has been removed. This functionality is likely better provided in a
user-space support library. In addition, read and write access is
supported. In addition, although the xps_hwicap cores support
interrupt-driver mode, this driver only supports polled operation, in
order to make the code simpler, and since the interrupt processing
overhead is likely to slow down the throughput under Linux.Signed-off-by: Stephen Neuendorffer
