This adds support for slave serial programming, in addition to the previously supported slave SelectMAP mode. There are two ways that this can be used: -Using the clk and wdata callbacks in order to write image data one bit at a time using pure bit-banging. This works, but is rather painfully slow with typical image sizes. -By specifying the wbulkdata callback instead, the image loading process can be offloaded to SPI hardware. In this mode the clk and wdata callbacks do not need to be specified. This allows the image to be loaded much faster, taking only a few seconds with even relatively large images. Slave serial programming has been tested on the Kintex-7 series of FPGAs. Signed-off-by: Robert Hancock <hancock@sedsystems.ca> Signed-off-by: Michal Simek <michal.simek@xilinx.com>
