This PR introduces some major features while also changing the project structure to be more flexible for multiple platforms (e.g. host tooling). Added features: 1. Pure Rust FSBL for the Zedboard. This first variant is simplistic. It is currently only capable of QSPI boot. It searches for a bitstream and ELF file inside the boot binary, flashes them and jumps to them. 2. DDR, QSPI, private CPU timer modules 3. Tooling to auto-generate board specific DDR and DDRIOB config parameters from the vendor provided ps7init.tcl file Changed project structure: 1. All target specific project are inside a dedicated workspace inside the `zynq` folder now. 2. All tool intended to be run on a host are inside a `tools` workspace 3. All other common projects are at the project root
