For 32-bit U-Boot, it is still -m32. Yes, what I'm trying to understand is 1. U-Boot is compiled _either_ 64-bit, _or_ 32-bit binary -- correct? 2. If above is correct then -m64 _enforces_ to compile it as 64-bit -- correct? Or I'm mistaken with the last and -m64 just adds a _preference_ to compile as 64-bit? -- With Best Regards, Andy Shevchenko _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
