The leading zeroes were removed from the addresses. With this a newer barebox doesn't find the nodes to fixup in an old device tree and an older barebox doesn't find the nodes in a new device tree. To fix this we create new names of the nodes based on things that hopefully don't change: We iterate up to a node which is MMIO space mappable and get a name that starts with "[adr]". For the remaining parts of a node we add "" when the hierarchy level has a "reg" property and only as last fallback we add "{nodename}" in curly brackets. This name is safe against node name changes and also against adding a new hierarchy level in the device tree (when for example a bus level is added). This series aims for v2018.01.1 Sascha Hauer (2): of: Add function to find the same node in another tree of: mtd: partition: Use reproducible node names for fixup drivers/of/base.c | 63 ++++++++++++++++++++++++++++++++++++++++++++++++++ drivers/of/partition.c | 5 +++- include/of.h | 5 +++- 3 files changed, 71 insertions(+), 2 deletions(-) -- 2.15.1 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
