[meta-xilinx] Options for automatically generating BOOT.BIN file for ZC702 using Yocto

[Mike Looijmans]

Basically, the same method as the other boards. You can use the 
u-boot-zynq-spl.bb recipe from meta-topic as an example, it builds the 
reference design using XPS, exports the SDK files which the u-boot 
recipe picks up to build the bootloader. I'm working on a better method 
to get the ps7_init.[ch], but as it is now, it doesn't need any manual 
actions, and no external tools like bootgen (well, you need XPS or 
Vivado to build the logic) to create a complete image from scratch. It 
also doesn't need an FSBL.

Best would be to have only the MIO and DDR configuration in the 
bootloader, and leave the rest for the kernel to configure. There is no 
pinmux support yet, but since everything you need is publicly available, 
anyone with some kernel hacking skill should be able to cook something 
up. By far the simplest starting point would be "if a device is 
initialized by the kernel, but not configured, assume it should be 
connected to the EMIO".
