There is no sense in sending a bitstream we know will not work, and with the variety of options for bitstream generation in Xilinx tools it is not terribly clear what the correct input should be. This is particularly important for Zynq since auto-correction was removed from the driver and the Zynq hardware only accepts a bitstream format that is different from what the Xilinx tools typically produce. Worse, the hardware provides no indication why the bitstream fails, it simply times out if the input is wrong. The best option here is to have the kernel print a message informing the user they are using a malformed bistream and programming failure isn't for any of the myriad of other reasons.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
