This PR introduces some major features while also changing the project structure to be more flexible for multiple platforms (e.g. host tooling). It also includes a lot of bugfixes, renamings for consistency purposes and dependency updates. 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. QSPI flasher for the Zedboard. 3. DDR, QSPI, DEVC, private CPU timer and PLL configuration 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 Major bugfixes: 1. SPI module: CPOL was not configured properly 2. Logger flush implementation was empty, implemented properly now.
