Are you expecting Tom Rini to apply it to the main U-Boot repo? Ahh, one of those fuzzy gray areas... the patch is to main.c, I mostly focus on files in the libfdt subdirectory. I can apply it via the FDT repo. Tom Rini, do you have any preference? The merge window closed May 11 and the original patch was emailed on May 14... is it a candidate to go into the July 15 release? It is a simple patch arguably fixing a bug, but it did miss the window. Thanks, gvb ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
