I had a further look at this, and I suspect we should stick to medlow for U-Boot, even for 64-bit. As U-Boot will be only running within the low 4GB memory space even for 64-bit. Adding medany seems unnecessary. Regards, Bin _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
