TI provides a set of headers files and libraries useful in developing
firmware for real-time (PRU) cores embedded in some processors e.g.
AM3358. This package stages these files for any packages creating
PRU firmware.
Note: As per [1], use commit v4.0.2 to sync with common TI Linux
versions.

Changes v1 --> v2
* change from staging to host package (thanks Arnout & Thomas)
* match upstream name of pru-software-support (thanks Arnout)
* ensured config dependencies are propagated (thanks Arnout)
* added a hash file (thanks Arnout)
* various little clean-ups
Changes v2 --> v3
* add option to build examples too (suggested by Arnout & Thomas)
* depend on ti-cgt-pru as we need it to compile

+PRU Software Support
+====================
+Two different packages are provided from the TI PRU software support code base.
+1. The include files and rpmsg static library for the PRU are installed
+ alongside the host package for the PRU code generation tools package i.e.
+ $(TI_CGT_PRU_INSTALLDIR).
+2. A target package for all the examples installed to
+ /usr/share/pru-software-support/. Users wanting to test a specific example
+ should copy or link it to a directory where the kernel looks for firmware
+ e.g. (at the root command prompt on the target)
+
+ # cp /usr/share/pru-software-support/am335x/PRU_gpioToggle/gen/PRU_gpioToggle.out \
+ /lib/firmware/am335x-pru0-fw
+
+To get started with the PRU, have a look at the labs [1].
