What exactly is > the problem? When I change a Minnowboard configuration (baytrail) to run in 64-bit mode, there are two conflicting definitions of misc_init_r(): arch/x86/cpu/x86_64/cpu.c board/intel/minnowmax/minnowmax.c On other CPU models, functions checkcpu() and print_cpuinfo() conflict with model-specific definitions for Tangier, Ivy Bridge, Broadwell, Quark. ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot

It looks like whatever you are going to add later needs actually a fully-established folder under arch/x86/cpu rather than (dirty) hacks here and there. -- Andy ShevchenkoIntel Finland Oy ___ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot

[U-Boot] [PATCH] x86: enable cpu-specific functions for x86_64 target
Add __weak prefix to the following functions to allow override: misc_init_r(), checkcpu(), print_cpuinfo().
