Just a concern. Technically, we have the same problem on e500, except on e500 we use multiple TLBs to map the memory. In theory, we need at most one TLB/BAT per DIMM slot, which means we would need four BATS on the MPC8641 HPCN. Do we want to tell customers that U-Boot/Linux only supports power-of-two sizes of DDR? -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
