This revision introduces CL_MAKE_RDONLY to propagate the request to make things

`mount -o bind,ro ...` suffers from a silent failure where the readonly

does not work when you want to define readonly bind mounts in fstab.

This driver allows programming the fpga from
device tree overlays.
This code is dependent on Pantelis Antoniou's current
work on Device Tree overlays, a method of dynamically
altering the kerel's live Device Tree. This patchset
was tested with Pantelis's and Grant Likely's stuff
From: Alan Tull
[resend with fixed email settings]
The idea of the framework is to provide consistent ways of
programming raw images into FPGA's.
Programming from device tree overlays is supported.
The core (fpga-mgr.c) does not include a userspace interface
and just exports kernel functions.
From: Alan Tull
Add basic sysfs interface. Only exports two files:
/sys/class/fpga_manager/fpga0/name
Name of low level driver.
/sys/class/fpga_manager/fpga0/status
status of fpga framework as returned by core
fpga-mgr.c's fpga_mgr_ops_framework_status
function or by the low level
From: Alan Tull
This core exports methods of doing operations on FPGAs.
EXPORT_SYMBOL_GPL(fpga_mgr_write);
Write FPGA given a buffer and count.
EXPORT_SYMBOL_GPL(fpga_mgr_firmware_write);
Request firmware and write that to a fpga
EXPORT_SYMBOL_GPL(fpga_mgr_status_get);
