+### Resource allocator v4 + +A new revision of resource allocator v4 is now added to coreboot that +supports mutiple ranges for allocating resources. Unlike the previous +allocator (v3), it does not use the topmost available window for +allocation. Instead, it uses the first window within the address space +that is available and satisfies the resource request. This allows +utilization of the entire available address space and also allows +allocation above the 4G boundary. The old resource allocator v3 is +still retained for some AMD platforms that do not conform to the +requirements of the allocator. + ### Add significant changes here
