Upon registering a FPGA Manager low level driver, FPGA Manager core overwrites the platform drvdata pointer. Prior to this commit zynq-fpga falsely relied on this pointer to still be valid at remove() time. Reported-by:

Ensure device and driver lifetime from of_fpga_mgr_get() to fpga_mgr_put(). * Don't put_device() in of_fpga_mgr_get, do it in fpga_mgr_put(). (still do put_device if there is an error). * Do module_get on the low level driver. * Don't need to module_get(THIS_MODULE) since we won't be allowed to unload the fpga manager core without unloading low level driver first. * Remove unnedessary null check for node pointer.

This patch is more of a personal preference, rather than a fix for a problem. The current implementation used a combination of both 'cat' and 'sed' to generate an unsorted list of kernel modules separated by while space. The proposed implementation uses 'sort' and 'sed' to generate a sort list of kernel modules separated by while space.

'loadkeys -h' no longer prints the version number across all distros, despite the claim to do so in the manpage, which I found to be the case on a Debian Linux system. The proposed implementation utilises the output of 'loadkeys -V' to acquire the version of both 'Kbd' and 'Console-tools'.

Gentoo Linux Debian 6.0.10 Oracle Linux Server release 7.1 Which results in zero ouput generated. The proposed implementation relies on 'ldconfig' to locate the libraries in question.

Rely on regex to find the version number, rather than rely on numerical input to be found in a particular input field. Proposed implementation also eliminates the necessity to invoke 'head' + 'awk'. The '-v' flag either seems to have been deprecated in some distros, e.g. Gentoo, or is an alias for '--version' in others. The proposed implementation uses the latter flag only. Signed-off-by:

The current implementation has been found not to work across all distros. The proposed implementation relies on 'sed' to both output the string 'Linux C Library' as well as to open '/proc/self/maps' without having to use output redirection.

The current implementation relies on 'fdformat' to output the version of 'util-linux'. This does not seem to be reliable any longer, as 'fdformat' does not seem to come preinstalled in all ditros these days. The proposed implementation uses 'mount' to output both the version of 'util-linux' and 'mount' proper, as 'mount' is also a part of the 'util-linux' package.

This change adds functionality to operate on reserved SRAM partitions described in device tree file. Two partition properties are added, "pool" and "export", the first one allows to share a specific partition for usage by a kernel consumer in the same manner as it is done for the whole SRAM device, and "export" property provides access to some SRAM area from userspace over sysfs interface. Practically it is possible to specify both properties for an SRAM partition, however simultaneous access from a kernel consumer and from userspace is not serialized, but still the combination may be useful for debugging purpose. The change opens the following scenarios of SRAM usage: * updates in a particular SRAM area specified by offset and size are done by bootloader, then this information is utilized by the kernel, * a particular SRAM area is rw accessed from userspace, the stored data is persistent on soft reboots, * a device driver secures SRAM area for its purposes, * etc. Note, strictly speaking the added optional properties describe policy of SRAM usage, rather than hardware, but here the policy mostly resembles flash partitions in devicetree, which is undoubtedly a very popular option but it does not describe hardware.
