Making Pi ServerReady: time for cheap Arm infrastructure be standards-compliant
summary
Project ports SBBR on Pi 4 by upstreaming a TianoCore UEFI payload and Trusted Firmware, adds PCIe/USB3 and onboard Ethernet so standard OS images (Debian, FreeBSD, ESXi-Arm, experimental Windows) boot. Key pain points are 1GB/3GB DMA limits, non‑ECAM PCIe layout and lack of PCI coherency; workarounds include a CPI DMA method and small Linux patches to unlock 4GB RAM and USB3. Repo, ACS reports and status pages show partial but working boots and ongoing upstream patches.
