You didn't mention lpj in the commit message. Did you get the number from kernel log? LS1012A is a single core SoC. How much time do you save by setting lpj?

I don't exactly remember how much but I think it was couple of 10's of milliseconds > > York ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
