[PATCH 0/6] Shrinking DT memory usage

2017-10-05 Thread Rob Herring
On kernels with a minimal config and a RAM target in the 100s of KB, DT is quite a hog of runtime memory usage. How much is dependent on how many nodes and properties in the DT which have a corresponding struct device_node and struct property in the kernel. Just skipping disabled nodes saves a lo
