2024-06-27commonlib/device_tree: Improve node and property allocation speedJulius Werner
Now that the device tree code has been made available in libpayload, we should reintroduce the node and property allocation optimization for libpayload's memory allocator that was originally dropped when porting this code from depthcharge to coreboot. On a Qualcomm SC7180 unflattening a normal ChromeOS kernel device tree, this saves roughly ~145ms. The total scratch space used is about ~1350 nodes and ~5200 properties, so we leave a little room to grow with the constants hardcoded here.
