The rev 1.1 and newer SoC supports both 4K and 64K. If you > don't do anything in PBI, the default is 64K. [] yes. You are correct . Does this 64k alignment apply to > any other SoCs? > [] This patch only apply to ls1043a. and the other SOCs only support one kind of alignment style. For example, ls1046a align with 64k, ls1012a align with 4k. > York _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
