summary
Converts a hardware XSA into a Yocto multi‑config that generates Linux, bare‑metal (newlib/libzil), PMU firmware and MicroBlaze images in one coordinated build using Vivado/XSA/DTG++ and lopper+dt processor and then packages FSBL/PMU/uboot into flash images. Prototype works end‑to‑end but multiplies work: builds jump from ~6k to ~10–15k tasks, build time from ~1.5h to ~2.5h, disk usage ~2.5×. Outputs DTBs today (moving to DTS for debugging); supports vendor binaries and per‑domain toolchains.
