From 878d68c0c357ff62120d5783d950f34ecd1065d9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 12 Jun 2017 06:21:31 -0600 Subject: dm: core: Add functions to obtain node's address/size cells The of_n_addr_cells() and of_n_size_cells() functions are useful for getting the size of addresses in a node, but in a few places U-Boot needs to obtain the actual property value for a node without walking up the stack. Add functions for this and just the existing code to use it. Add a comment to the existing ofnode functions which do not do the right thing with a flat tree. This fixes a problem reading PCI addresses.
