[U-Boot] [PATCH 00/17] More Ethernet initialization rework
by Ben Warren 31 Aug '08

31 Aug '08

Hello, This patch set moves initialization of most Ethernet controllers to board or CPU code. A few of the more complicated ones remain, but the goal is to implement this on all controllers. Notes: 1. I obviously wasn't able to test many of these. I compiled what I could with the tools on hand, but there's a chance for some breakage. 2. Many, many boards are affected by this. I didn't copy the individual board maintainers because, well, that would be a lot of work :) Each patch lists the boards that are modified directly. 3. I've tried to design this so that people can still choose different PCI-based Ethernet controllers with a simple CONFIG change. I appreciate feedback on this implementation. regards, Ben

[U-Boot] libfdt: Fix bugs in fdt_get_path()
by Jerry Van Baren 31 Aug '08

31 Aug '08

FYI, I propose to pick this up for the *NEXT* release of u-boot ("Yellow Submarine" ;-). My reasoning is that (1) the current window closes today, which makes me uncomfortable WRT putting in changes today and (2) this appears to be a latent bug (at worst, a misleading error message); I have not seen evidence that it is causing problems at the moment. Best regards, gvb David Gibson wrote: > The current implementation of fdt_get_path() has a couple of bugs, > fixed by this patch. > > First, contrary to its documentation, on success it returns the length > of the node's path, rather than 0.
