+## Make coreboot ARM (L)BBR compliant
+The ARM [BBR](https://developer.arm.com/documentation/den0044/f/), Base Boot
+Requirements is a firmware specification describing how ARM64 servers and
+hyperscalers should load an operating system. The main purpose of this
+specification is to boot Operating systems like Linux without
+[devicetree](https://www.kernel.org/doc/html/latest/devicetree/usage-model.html)
+but using SMBIOS, ACPI and UEFI runtime services.
+
+Currently coreboot has no support for SMBIOS or ACPI.
+coreboot also does not support runtime services by design.
+The mandated UEFI runtime services seem only useful to provide Linux both
+SMBIOS & ACPI.
+
+So the scope of this project would be:
+* Port the QEMU aarch64 sbsa-ref machine to coreboot
+* Implement SMBIOS on ARM64
+* Implement ACPI on ARM64
+* Investigate how to provide minimal UEFI runtime services, e.g. in a payload
+  or better find an (upstreamable) way in Linux on how to pass ACPI & SMBIOS without
+  UEFI runtime services
+
+### Requirements
+* Hardware knowledge: Nothing (target is emulated)
+* coreboot knowledge: Know how tables are generated/injected and passed to
+  Payloads
+* Linux knowledge: Being able to compile and debug it. Some knowledge on the
+  boot process is certainly helpful.
