I will do it now for clarity. Ok -- Vincent's patch was not in my Patchwork TODO and I had read patches 1/2 and 2/2 in Patchwork, but I had not read the cover letter thoroughly enough so I had missed the dependency. (Cc:ing Vincent and Tom) Vincent's patch series is delegated to Tom and marked "superseded" in Patchwork but I don't see any later, superseding, series. What can/should I make of it? > Regards, > Sricharan Amicalement, -- Albert. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
