I applied 14 patches and left 4 below that have open questions: http://patchwork.ozlabs.org/project/uboot/list/?series=105795 In the meantime, it looks that travis-ci complained some failures in my last run for the applied patches. I will redo the travis-ci and let you know the results. Regards, Bin _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
